Diagnosis: Relatively small, fairly rigid, R to 7 cm; disc small, rays moderately long, slender, tapering. Abactinal plates close-set, forming a tight reticulation, very spinose. Abactinal surface with three radial rows per ray of very tightly packed spinose plates forming conspicuous lines; similar rows of tightly packed or fused plates at ray arcs, forming internal septa; color in life red with lighter radial lines. Description: Relatively small, R to 6 cm (Holotype R = 5.7 cm), r to 1.2 cm, R:r 5–6: 1 (Figs. 14 & 15); disc small, rays moderately long, slender, sub-cylindrical, tapering to blunt tips. Abactinal surface (Fig. 16) thick, semi-rigid; abactinal plates relatively small, close set, forming a tight reticulation some plates very close set or fused into linear series, lacking papular areas between, forming three distinct lines on rays, similar linear series of plates at ray arcs, forming internal septa; plates crowned with 9–35 spinelets tipped with 3–8 very sharp thorns; papular areas rather small, with 1–3 papulae; madreporite small, circular, spinose, located about half way between anus and edge of disc, at the end of the ray arc linear plate series. Superomarginals slightly larger than abactinal plates, inferomarginals about twice high as high as long; twice as large as abactinal plates and bearing 40–50 spine tipped spinelets; a single series of intermarginals extends about 1 / 3 to 1 / 2 of R; a primary actinal inter-radial series extends about 90 % of R, a second series extends about 1 / 4 to 1 / 2 of R. Adambulacrals (Fig. 17) with a single deep furrow spine and 14–17 actinal spines, one to three longer and somewhat compressed spine(s) at furrow edge, and 13–15 smaller distally grading spines behind. Oral plates (Fig. 18) five marginal and four to six suboral spines; in addition there are two to four thick, blunt, triangular, teeth deep in the furrow near the distal edge of the plate. Color in life (Fig. 19), red abactinally, with pale red to yellow-orange radial lines; orally yellow-orange. Dried specimens retain the lined pattern. Distribution: Found throughout the Aleutians from Fox Islands Avatanak Island, (54 º 05.188 N, 165 º 22.839 W) (leg. R.N. Clark, 12 June, 2008; scuba 6 m) to Near Islands, Attu Island, Chichagof Harbor (52 º 55.861 N, 173 º 15.295 E) (leg. R.N. Clark, 4 June, 2008; scuba 7 m) (Type locality) at depths of 6– 25 m. Also present at Bering Island, Commander Islands, Russia (55 º 11 ' 44 " N, 165 º 59 ' E) (per. com. Ken Vicknair, April, 2008), and along the Kamchatka, Russia coast (www.sanamyan.com). Henricia lineata is a member of the Aleutian Province, but the extent of its amphi-Pacific distribution requires further investigation. Habitat: Subtidal boulders and bedrock covered with the thick encrusting coralline red algae Clathromorphum. Etymology: Named for the brilliant red stripes on the rays. Remarks: This species has long been confused with the similar Henricia multispina Fisher, 1910 (Fig. 20), under the mistaken identification of Henricia spiculifera (H.L. Clark, 1901). This latter species has not been identified since Clark' s time. Clark's description differs on various points from that of H. multispina, and the type was from the vicinity of Puget Sound, Washington. An attempt to locate the type of H. spiculifera was unsuccessful, and it is presumed lost. It is therefore recommended that this name be treated as nomen inquirendum until the type or material from near the type locality that fits the original description can be located. Henricia lineata may be distinguished from H. multispina by 1) the prominent series of close-set aboral plates forming distinctive lines on the abactinal surface; 2) much smaller aboral plates; 3) relatively shorter, thicker, blunt-tipped rays, those of H. multispina are much more slender and pointed at the tips; and 4) dark reddish color, compared to white or pale lavender for H. multispina.Published as part of Clark, Roger N. & Jewett, Stephen C., 2010, A new genus and thirteen new species of sea stars (Asteroidea: Echinasteridae) from the Aleutian Island Archipelago, pp. 1-36 in Zootaxa 2571 on pages 10-12, DOI: 10.5281/zenodo.29423

LACM 2011 - 159.001; genetic sample LACM 2011 - 159.002 Alaska, Aleutian Islands, Amchitka Island, SE side, W of Makarius Bay (51 ° 23.16 N, 179 ° 11.02 E). Diagnosis.Star of moderate size; R to 9 cm, R:r 6–9 (Fig. 1). Five rays, relatively long; abactinal ossicles 2–4 lobed, with single spines; spines relatively short, stout, truncated bearing numerous fine vertical ridges; superomarginal and inferomarginal ossicles bear a single thick, blunt spine, similar to abactinal spines; all spines wreathed with numerous crossed pedicellariae. Tube feet, in four rows. Color in life reddish with lighter mottlings abactinally, actinal surface straw colored. Description. Moderate sized star R to 9 cm, r = 1 cm, R:r 9.1 (Holotype, Fig. 1). Disc small, five rays, fairly long, tapering, relatively soft. Skeleton relatively open; papular areas relatively large, bearing 3–6 papulae, obscured by wreaths of pedicellariae on spines in live individuals; bearing scattered large straight pedicellaria to 1.25 mm long (Figs. 2–3) on papular areas; pedicellariae broadened distally, and bearing four “teeth” per valve. Carinal ossicles 2–4 lobed, bearing single spines, dorsolateral ossicles single spined, also 2–4 lobed, but forming a more open meshwork (Fig. 4), and bearing small, irregular accessory plates; spines relatively short, thick truncated, with strong vertical ridges continuing onto the dorsal surface; encircled by a fleshy wreath of small, crossed pedicellariae up to 0.25 mm in length (Figs. 4–5). Madreporite small, about 3.5 mm in diameter, roughly circular with irregular ridges. Superomarginal ossicles 4 lobed and inferomarginal ossicles 3–4 lobed (Fig. 6), typically bearing single (rarely two) pedicellariae-wreathed spines, longer and more slender than those of the carinal and dorsolateral series. Actinal ossicles (Fig. 6) in a single nearly complete series, and bearing a single spine. Adambulacral ossicles (Figs. 7–8) bearing single spines on proximal five, then alternating one and two, (two spines in a vertical series), the proximal spine about ¾ as long and thick as the distal spine; actinal and adambulacral spines with a partial wreath on distal side of variously sized straight pedicellariae 0.25 to 0.75 mm. Oral ossicles narrow, bearing two rather slender spines with partial wreaths of pedicellariae similar to those of the actinal and adambulacral series. Tube feet in four rows. Color in life: dorsal surface reddish with dark and pale mottlings; spines and madreporite white; oral surface straw colored (Fig. 9–11). Paratype (Fig. 10) agrees with the holotype in all respects, but is smaller, R = 6 cm, r = 1 cm, R:r 6.1 and has somewhat stouter rays. Distribution. The distribution of L. tatei sp. nov., as well as L. stolacantha (Fig. 12) is the central Aleutian Islands, Andreanof and Rat Islands (approx. 176 ° W to 178 ° E) (Fig. 13). Leptasterias tatei sp. nov. was found at Adak (Holotype, Fig. 1; in situ, Fig. 9), Amchitka (Paratype, Fig. 10), and Hawadax (formerly Rat) (in situ, Fig. 11; not collected) islands. Additional specimens were photographed at Adak as well, but not collected. Habitat. Found on cobble, boulder and bedrock substrate encrusted with the coralline algae Clathromorphum nereostratum, at depths of 8–16 m, and temperatures of 3.8 ° to 5.0°C. Etymology. The name honors Mr. Paul Tate. For more than 40 years he worked throughout the Aleutian Islands, first as a biologist for the Alaska Department of Fish and Game in Dutch Harbor, later as the Captain of the research vessel Norseman. Remarks. Leptasterias tatei sp. nov. resembles L. stolacantha Fisher, 1930 (Fig. 12), but differs in 1) its larger size, 2) having thicker spines, 3) wreaths of fewer and larger crossed pedicellariae, to 0.25 mm in length, and scattered large straight, pedicellariae to 1.25 mm, as opposed to 0.13 mm and 0.37 mm, respectively in L. stolacantha, 4) the superomarginal and inferomarginal ossicles bear single spines in L. tatei sp. nov., as opposed to two (sometimes three) in L. stolacantha. Additionally, the spines of L. stolacantha are slender and needle-like. The color of live L. stolacantha also differs in being uniformly tan or light brown. Although its thick, truncated abactinal spines and large, straight pedicellariae clearly distinguish Leptasterias tatei sp. nov. from all other Aleutian species, it bears some resemblance to four congeners described by Dyakonov (1950) from the western part of the Okhotsk Sea, chiefly near Sakhalin Island. Leptasterias fisheri Dyakonov, 1929 differs from L.tatei sp. nov. by having the aboral spines arranged in more or less longitudinal rows; L. tatei sp. nov. has random arrangement. Leptasterias tatei sp. nov. is distinguished from Leptasterias hirsuta Dyakonov, 1938 by the truncate tips of the aboral spines, and single spines on the inferomarginals. The spines of L. hirsuta have rounded tips. Also, L. hirsuta has diverse types of straight pedicellariae scattered aborally that are smaller than those of L. tatei sp. nov. Leptasterias tatei sp. nov. differs from Leptasterias orientalis Dyakonov, 1929 in having only a single row of actinal ossicles. Leptasterias orientalis has two rows of actinal ossicles (ventolaterals in Dyakonov), and the spines on the inferomarginals change from one to two at about mid-ray. Also, the aboral spines of L. orientalis are long and very fine (acicular). Leptasterias tatei sp. nov. differs from Leptasterias subarctica Dyakonov, 1938 in having smaller actinal ossicles than inferomarginal ossicles; the actinals of L. subarctica are notably larger than the inferomarginals. Also, L. tatei sp. nov. has profuse wreaths of crossed pedicellaria around the aboral spines; the wreaths of L. subarctica are much sparser.Published as part of Clark, Roger N. & Jewett, Stephen C., 2015, A new sea star of the genus Leptasterias (Asteroidea: Asteriidae) from the Aleutian Islands, pp. 579-584 in Zootaxa 3941 (4) on pages 580-583, DOI: 10.11646/zootaxa.3941.4.6, http://zenodo.org/record/24451

Diagnosis: Relatively small, fairly rigid, R to 5.3 cm (Holotype R = 4.5 cm), r to 10 cm, R:r 5–5.3; disc small, rays moderately long, slender, tapering. Abactinal plates small, close-set; some plates may form a single fine, faint medial line or ridge on the rays. Adambulacral plates with 19–24 fairly stout, compressed spines. Description: Relatively small, R to 5.3 cm, r to 1.0 cm, R:r 5–5.3; disc small, rays moderately long, slender, tapering to fairly blunt tips (Figs. 21 & 22). Abactinal plates very small, close-set (Fig. 23); pseudopaxillae round on disc, becoming triangular on rays, forming a tight reticulation, some apical plates often very close-set, nearly coalescing, forming a single very fine line or ridge at apex of ray; plates crowned with 37–60 fine, divergent, thorn-tipped spinules, about 0.25 to 0.30 mm in length; usually 3 slender thorns per spinule; papular areas rather small, with 2 –3 papulae; madreporite small, circular, irregularly radially spinose, located about 1 / 3 of the distance between the anus and the edge of the disc. Superomarginals 2 or 3 times as large as abactinal plates; inferomarginals about 1 / 3 third larger than superomarginals, and bearing 60–70 thorny spinules; first intermarginal series about 1 / 2 as large as inferomarginals at base of rays, grading smaller aborally, extending about 40–50 % of R, second series ends just pass the base of the rays; actinal interradial series extending 75–80 % of R. Adambulacrals (Fig. 24) with a single deep furrow spine, and 19–24 actinal spines, one (or two) large, thick, blunt spines at edge of furrow, backed by 2–3 similar spines, followed by a group of 16–20 smaller spines behind (usually arranged in 3 rows). Oral plates (Fig. 25) with 3–4 thick, blunt marginal spines, and 6–9 similar, sub-oral spines; in addition there are two to four thick, blunt, triangular, teeth deep in the furrow near the distal edge of the plate. Color in life (Fig. 26) uniformly bright red. Distribution: Found from Fox Islands, Avatanak Island (54 º 05.188 N, 165 º 22.839 W) (leg. R.N. Clark, 12 June, 2008) to Andreanof Islands, Atka Island, Crescent Bay, point at W end (leg. R.N. Clark & Robert Lauth, 8 July, 1997) at depths of 0– 12 m. Henricia uluudax appears to be an endemic Aleutian species. Habitat: Intertidal and shallow subtidal, on cobbles and boulders encrusted with coralline red algae. Frequently in kelp beds [Eualaria (Alaria) fistulosa and Nereocystis luetkeana]. Etymology: The name is the Aleut native word for red; (pronounced ō lō thux). Remarks: Henricia uluudax is very similar superficially to H. lineata, but may be distinguished by 1) the lack light colored lines of coalescing plates; 2) more numerous abactinal spinules, 37–60, compared to 18–41; 3) more numerous inferomarginal spines, 60–70, opposed to 28–36; and 4) more numerous adambulacral spines, 19–24 compared to 15–17. The spinose nature of this form led Fisher (1911) to consider this an "extreme variant" of H. multispinosa, and Verrill thought it to be (at least in part) H.L. Clark's Cribrella spiculifera. It differs from the similar appearing H. vermilion by 1) the slender body; 2) differently shaped abactinal plates; 3) much more slender, divergent pseudopaxillar spinules, which bear (usually) just 3 long thorns, those of H. vermilion are pointed and bear numerous thorns, 4) the much more numerous adambulacral spines, 19– 24 as opposed to 7–10 in H. vermilion; and 5) presence of extensive intemarginal series. From the southern H. leviuscula, it differs in having slender, divergent, 3 -pronged abactinal spinules, and an intermarginal series extending to about 50 % of R, H. leviuscula lacks an intermarginal series. True H. leviuscula is not known to occur north of extreme southeastern Alaska (Doug Eernisse, pers. comm., March, 2009). This species is part of a complex of several very similar appearing Henricia in the Aleutians.Published as part of Clark, Roger N. & Jewett, Stephen C., 2010, A new genus and thirteen new species of sea stars (Asteroidea: Echinasteridae) from the Aleutian Island Archipelago, pp. 1-36 in Zootaxa 2571 on pages 12-14, DOI: 10.5281/zenodo.29423

Walters argument of Gordon Hirabayashi's case in the Supreme Court. Baldwin quotes Joseph Conard's letter (chs_ms3580_0196) warning of Walters' poor performance representing Hirabayashi in the Circuit Court of Appeals at San Francisco. Baldwin writes: "I should think it would be wise now, in the event of an adverse decision which is expected, to see that somebody else than Mr. Walters argues the case in the Supreme Court. We should be very glad to make recommendations if you wish."The ACLU-Northern California case file records contain legal documents and correspondence pertaining to the case Ex parte Mitsuye Endo (1944), in which the United States Supreme court unanimously ruled that the federal government could not indefinitely detain United States citizens who were loyal to the government.

Diagnosis: Relatively small star; R to 7 cm; disc small, rays relatively stout to moderately long R:r 4.5– 5.8; rays with three rather faint, fine, longitudinal lines of close-set plates; skeleton thin, abactinal plates small, rounded, bearing 17–35 spinelets. Length inferomarginals about 1.5 to 2 times width. Adambulacrals, with 30–40 + spines. Color, uniformly crimson. Description: Relatively small, fairly soft star Holotype (Figs. 65–69), R 6 cm, r 1.1 cm, R:r 5.4 R:r range 4.1 –6.8; disc small, rays relatively stout to moderately long, tapering to slender, tips. Abactinal plates small, forming a fine-meshed reticulum, some plates very close set or fused into linear series, lacking papular areas between, forming three fine, lines on rays (Fig. 67; paxillae mostly round, bearing (usually) 17–35 (exceptionally up to nearly 50) spinelets tipped with 3–5 very sharp thorns; papular areas small, with 1–2 papulae; madreporite very small, circular, with irregular, radially spinose ridges, located closer to the anus than to the edge of the disc. Superomarginals about three times as large as adjacent actinolateral plates, and bearing about 35–40 thorn tipped spinelets; inferomarginal plates about twice (or less) as high as long, only slightly (+/- 1 / 3) larger than superomarginals, and bearing 43–56 thorn tipped spinelets; intermarginal plates irregular at base of rays, extending along rays in two series, about 60 % and 40 % of R, respectively. Adambulacrals (Fig. 68) with a single small spine deep in the furrow and 35–45 spines on the actinal surface, proximal 5–8 very large, thick, blunt, often somewhat compressed followed by 37–40 + much smaller, finer spines in a group, or 4–5 rows. Oral plates (Fig. 69) with 5 thick, blunt marginal and 20–25 suboral spines. Color (Fig. 70) in life uniformly crimson. Distribution: Henricia insignis is found throughout the central Aleutians, from the Islands of Four Mountains, Chuginadak Island (52 º 48.289 N, 169 º 42.526 W) (AKALE 06-0010) to Rat Islands, Kiska Island (51 º 54.869 N, 177 º 26.865 ’E) (AKALE 07-0017) at depths of 0– 210 m. Habitat: Boulders and bedrock in shallow water (<20 m), covered with the thick encrusting coralline red algae Clathromorphum. In deeper waters, it is found on sand and cobble bottoms dominated by sponges and hydrocorals. Etymology: The name is from the Latin and means remarkable, in reference to its brilliant red coloration. Remarks: As with its congeners Henricia lineata and H.uluudax, H.insignis was thought by earlier workers (Fisher, 1911, Verrill, 1914) to be a variety or hybrid of H. multispina (see remarks under H. lineata). This species appears to be one of the varieties mentioned by Fisher (1911: 288). Henricia insignis may be distinguished from the similar H. lineata by 1) thinner skeleton, uniformly red coloration and more sharply tapering rays; 2) lack of distinctive light colored radial stripes on rays; 3) more open reticulation; 4) two rows of intermarginal plates, compared to one row in H. lineata; and 5) much more numerous adambulacral spines 35–45 + opposed to 14–17 in H. lineata. The two species are frequently found in the same habitat. Henricia insignis superficially resembles H. uluudax, but differes in 1) much thinner skeleton; 2) smaller abactinal plates, bearing much fewer spinules, 17–35 compared to 37–60; and 3) much more numerous adambulacral spines 35–45 + opposed to 19–25 in H. uluudax. From H. multispina it may be distinguished by 1) the relatively shorter rays (R:r 4.5 to 5.8 compared to 5.8–7.2 for H. multispina; 2) fewer abactinal spinules 17–35 opposed to 50–100 + in H. multispina; 3) intermarginal plates extending in two series, 40–60 % of R, in H. multispina the intermarginals absent, or restricted to a few irregular plates at base of rays; 4) shorter inferomarginal plates, length 1.5 to 2 times width, compared to 2.5 to 3 times in H. multispina; and 5) coloration, brilliant red in H. insignis, lavender to white in H. multispina (typically lavender on disc and upper portion of rays, fading to white on ray extremities). The adambulacral spine numbers are very similar, though H. insignis usually has a few more.Published as part of Clark, Roger N. & Jewett, Stephen C., 2010, A new genus and thirteen new species of sea stars (Asteroidea: Echinasteridae) from the Aleutian Island Archipelago, pp. 1-36 in Zootaxa 2571 on pages 24-26, DOI: 10.5281/zenodo.29423

No full textIncludes bibliographical references and index.Book fair 2013.xvii, 1080 p. :Edited by renowned protein scientist and bestselling author Roger L. Lundblad, with the assistance of Fiona M. Macdonald of CRC Press, this fourth edition of the Handbook of Biochemistry and Molecular Biology represents a dramatic revision -- the first in two decades -- of one of biochemistry's most referenced works. This edition gathers a wealth of information not easily obtained, including information not found on the web." "Offering a molecular perspective not available 20 years ago, it provides physical and chemical data on proteins, nucleic acids, lipids, and carbohydrates. Presented in an organized, concise, and simple-to-use format, this popular reference allows quick access to the most frequently used data. Covering a wide range of topics, from classical biochemistry to proteomics and genomics, it also details the properties of commonly used biochemicals, laboratory solvents, and reagents." "Just a small sampling of the wealth of information found inside the handbook" : "Buffers and buffer solutions" -- "Heat capacities and combustion levels" -- "--Reagents for the chemical modification of proteins" -- "Comprehensive classification system for lipids" -- "Biological characteristics of vitamins" -- "A huge variety of UV data" -- "Recommendations for nomenclature and tables in biochemical thermodynamics" -- "Guidelines for NMR measurements for determination of high and low pka values" -- "Viscosity and density tables" -- "Chemical and physical properties of various commercial plastics" -- "Generic source-based nomenclature for polymers" -- "Therapeutic enzyme

Whorls at all stages rounded, suture deeply impressed. Apex extended by addition of one very extended early teleoconch whorl. Axial and, spiral sculpture usually lacking or composed of a few very faint, irregular spiral cords, pillar straight or slightly concave. Canal of moderate length, final lip thickened, but not flaring. Operculum relatively large, but not filling aperture, nucleus terminal.</p> <p> <b>Type species:</b> <i>Laevisipho galaxaios</i> <b>n. sp.</b> (HD).</p> <p> <b>Remarks:</b> This genus differs from the similar smooth shelled genus <i>Golikovia</i> Habe & Sato, 1973, by 1) nuclear whorls, which are extended as in <i>Beringius</i>, and 2) lack of spiral cords on early teleconch whorls. The nuclear whorls of <i>Golikovia</i> are not extended, and the early teleconch whorls have several spiral cords. Differs from other smooth or nearly smooth <i>Neptunea</i> (<i>s. l.</i>) by the extended protoconch which lacks any spiral cords or angulation.</p> <p> Two species are recognized, <i>Laevisipho galaxios</i>, and <i>L. kessleri</i>, both endemic to the central Aleutian Islands.</p>Published as part of <i>Mclean, James H. & Clark, Roger N., 2023, Seven new genera and thirty-four new species of buccinoid gastropods (Neogastropoda: Buccinidae) from the Aleutian Islands, Alaska, pp. 151-201 in Zootaxa 5351 (2)</i> on page 185, DOI: 10.11646/zootaxa.5351.2.1, <a href="http://zenodo.org/record/8391375">http://zenodo.org/record/8391375</a>
