Protaspis gemmifera Larsen and Patterson 1990
No full textProtaspis gemmifera Larsen and Patterson, 1990 (fi gures 22i, 23f -h) Description. Cell outline oval or roundish, 9-16 Mm long and 9-11 Mm wide, dorso-ventrally fl attened. Cell surface is rather warty. Two fl agella insert subapically in an indistinct ventral furrow. The anterior fl agellum is as long as the cell and the posterior fl agellum is about 1.3-3 times the cell length. The posterior fl agellum inserts in an antero-posterio r line of the anterior fl agellum and trails behind the cell. The nucleus is situated anteriorly below the fl agellar insertion, has caps and is roundish. Reserve material may be present as oval or rod shaped bodies. Glides very fast with the anterior fl agellum. Produces pseudopodia from the ventral furrow. Sometimes commonly observed. Description based on observations of 33 cells. Remarks. Generally, our observations agree with the original description of Larsen and Patterson (1990) although they did not refer to the warty surface. Protaspis gemmifera was recorded from Brazil and North Atlantic by Larsen and Patterson (1990) and Patterson et al. (1993), respectively. Cell lengths were previously reported as 10-17 Mm (Larsen and Patterson, 1990; Patterson et al., 1993). Nuclear caps were not seen in any of the cells described by Patterson et al. (1993) but this character may have been overlooked because the nuclear caps may be di ffi cult to see in fast moving cells. Some cells did not have reserve materials in the posterior end of the cell, and reserve materials may not be useful as a diagnostic character although we have not seen the distinctive rod-shaped reserve materials in any species other than this one. Protaspis gemmifera resembles P. verrucosa Larsen and Patterson, 1990 in general appearance and length, but it has been distinguished by the longitudinal ventral furrow in P. verrucosa and the presence of nuclear caps in P. gemmifera. Figure 60b in Larsen and Patterson (1990), which is the type micrograph for P. verrucosa, shows some similarity to our cells in fi gure 23h. We are not sure whether these two species are clearly distinguishable. Protaspis gemmifera is probably detritivorous (Patterson et al., 1993). The organism referred to as P. simplex by Tong et al. (1998) has probably been illustrated by pictures of P. gemmifera, but having consulted original records, we can con fi rm that both species were present. The genus contains nine species: P. gemmifera Larsen and Patterson, 1990, P. glans Skuja, 1939, P. major Skuja, 1939, P. metarhiza Skuja, 1939, P. obovata Skuja, 1948, P. obliqua Larsen and Patterson, 1990, P. simplex Vørs, 1992, P. tegere Larsen and Patterson, 1990 and P. verrucosa Larsen and Patterson, 1990. The boundaries among many species are not clear (table 2), and this genus needs more attention.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 54
Petalomonas poosilla Larsen and Patterson 1990
No full textPetalomonas poosilla Larsen and Patterson, 1990 (fi gures 14g, h, 16e -g) Description. We describe two populations of cells. Population 1: small cells; ovate, 5-9 Mm long, 3-5 Mm wide, dorso-ventrally fl attened. This species may or may not have up to three dorsal ridges and the ridges may or may not be well developed. The organism may also have two fi ne ventral ridges which are di ffi cult to observe. The right ventral ridge runs beneath the reservoir along the cell. With one fl agellum as long as the cell. The reservoir is in the right side of the cell and the nucleus is in the left side. Moves by gliding. Common. Population 2: Larger cells; cell outline oblong-oval, 10-12 Mm long and 5-6 Mm wide, dorso-ventrally fl attened. It has four ridges extending along the cell: two indistinct dorsal ridges located at the lateral margins of the cell; two fi ne ventral ridges, the right one of which runs beneath the reservoir. One fl agellum is about as long as the cell or slightly longer. The ovate reservoir is anteriorly situated in the right-hand side of the cell and the nucleus in the left-hand side of the cell. Often co-occurs with the smaller cell. Remarks. Larsen and Patterson (1990) provided a new name for P. pusilla Skuja, 1948 (P. poosilla) because under the principle of co-ordination of the ICZN, P. pusilla Skuja, 1948 is a homonym of P. mediocanellata var. pusilla Klebs, 1893 (Lemmermann, 1913)—which we refer to as P. minuta (see P. minuta above). Petalomonas poosilla and P. minuta resemble each other in shape and appearance, but can be distinguised by the presence of what we regard as a longitudinal groove in P. minuta. Petalomonas poosilla was originally described under the name P. pusilla (5-12 Mm long) from freshwater sites (Skuja, 1948) and has since been found in marine sites in Australia, Brazil, Danish Wadden Sea, Fiji, Gulf of Finland; Hawaii and NE Canada (Lackey and Lackey, 1970; Larsen, 1987; Larsen and Patterson, 1990; Vørs, 1992a; Patterson and Simpson, 1996; Tong et al., 1998). We observed cells (in the small population) which are similar in size and outline to P. poosilla as described by Larsen and Patterson (1990). This species has been described without ridges or grooves (Skuja, 1948; Larsen and Patterson, 1990). Cells assigned to this species have been described more recently as having ridges (Patterson and Simpson, 1996; Schroeckh and Patterson, unpubl.). We suspect that this species has previously been under-described and regard the latter descriptions as more accurate than the former. The ventral face of this species is very similar to that of P. minor, described here, in having two fi ne ventral ridges and in the position of the ridges, but the two species can be distinguished by cell shape and the dorsal fl ange in P. minor. Petalomonas poosilla and P. minuta resemble each other in shape and appearance, but can be distinguised by the presence of what we regard as a longitudinal groove in P. minuta. This species resembles P. cantuscygni (see Cann and Pennick, 1986) from which it can be distinguished by never having fewer than six dorsal ridges. We have observed larger cells about 10-12 Mm long, but they consistently had four discrete ridges on both sides of the cell. The two populations often co-occur. Although these may represent a separate species, we have been unable to establish morphological discontinuities by which single cells could be easily identi fi ed when comparisons are made. Further studies are required to establish the status of the two populations.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on pages 523-52
Ploeotia pseudanisonema Larsen and Patterson 1990
No full textPloeotia pseudanisonema Larsen and Patterson, 1990 (fi gures 17e, 19a, b) Description. Cell outline oblong or elliptical, about 20 Mm long and 10 Mm wide, fl attened. With several longitudinal narrow grooves extending along the cell. The left half of the cell is thicker than the right half. The anterior fl agellum is about 1.5 times the cell length, and the posterior fl agellum is about 4 times the cell length, emerges as a hook from the fl agellar canal and is stronger than the anterior fl agellum. The posterior fl agellum lies in a ventral groove and tapers towards the tip of the fl agellum. The nucleus is located near the middle of the cell and the reservoir is in the left ventral side. The ingestion organelle is well developed. Cell glides quickly and may jerk backwards—like Anisonema. One cell observed. Remarks. Larsen and Patterson (1990) fi rst described this species from marine sites in Australia, Brazil, Fiji and Hawaii, and this species has also been reported from other locations in Australia by Ekebom et al. (1996), Patterson and Simpson (1996) and Tong et al. (1998). Previously reported lengths range from 10 to 19 Mm. Generally, our observations agree with the description by Larsen and Patterson (1990). This species is similar to P. longi ®lum Larsen and Patterson, 1990 in having a long trailing fl agellum and in size, but is distinguished by general appearance and one ventral groove in P. longi ®lum. Also, P. pseudanisonema resembles P. punctata Larsen and Patterson, 1990 in general appearance and in having a long posterior fl agellum, but it is distinguished because small internal bodies in P. punctata line the dorsal ridges. Ploeotia pseudanisonem a is similar to Anisonema obliquum Roskin, 1931 and A. trepidum Larsen, 1987 in general appearance and length (Roskin, 1931; see Larsen, 1987), but is distinguished by the presence of an ingestion organelle.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 53
Oligosoma notosaurus Patterson & Daugherty 1990
No full textOligosoma notosaurus (Patterson & Daugherty, 1990) A full description of O. notosaurus is contained in Patterson & Daugherty (1990). For the current study we reexamined all of the specimens included in the original description apart from the holotype, which has been lost from the Te Papa collection.Published as part of Chapple, David G., Bell, Trent P., Chapple, Stephanie N.

World War I record of service for Daniel W. Patterson, signed 20 February 1926.
No full textQuestionnaire with information about Daniel Walter Patterson's service in World War I, 1917-1919, signed by Patterson on 20 February 1926.Questionnaire originally part of a survey of Norwich University alumni conducted by a “Norwich in the World War” committee consisting of Charles N. Barber (chairman), Carl V. Woodbury, K.R.B. Flint, and Gustaf A. Nelson. Data from these questionnaires may have been used in a chapter of "Vermont in the world war, 1917-1919" by Harold P. Sheldon (1928)
Petalomonas minor Larsen and Patterson 1990
No full textPetalomonas minor Larsen and Patterson, 1990 (fi gures 14d, 16a -d) Description. Cell outline ovate-rhomboid, 6-11 Mm long, 4-8 Mm wide. A distinct, longitudinal dorsal keel lies to the right of the midline. Two fi ne ventral ridges may be seen towards the posterior end. The dorsal face is slightly concave between the longitudinal dorsal keel and the lateral margin of the cell. With one fl agellum about the same length as the cell inserting in a reservoir located in the right side of the cell. The nucleus is in the left side. Glides with the fl agellum directed forwards. Commonly observed. Descriptions based on observations of 28 cells. Remarks. Larsen and Patterson (1990) fi rst described this species from marine sites in tropical Australia and Fiji. They reported lengths ranging from 7 to 9 Mm. Generally, our observations are in accordance with observations of Larsen and Patterson (1990), but the species described here has two fi ne ventral ridges not reported by Larsen and Patterson (1990). They could easily have been overlooked. The species resembles P. poosilla (see below) in having two fi ne ventral ridges and in length, but it can be distinguished by its dorsal keel and cell shape. In having one distinct dorsal keel, the species is similar to a few other species in the genus Petalomonas such as P. lata Christen, 1962, P. steinii Klebs, 1893 and P. variablilis Christen, 1962 (see Huber-Pestalozzi, 1955; Christen, 1962b). It can be recognized from all of these by its small size.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on page 52
Ploeotia discoides Larsen and Patterson 1990
No full textPloeotia discoides Larsen and Patterson, 1990 (fi gures 17b, 18e -g) Description. Cell outline oval or elliptical, 11-13 Mm long, 7-8 Mm wide, dorsoventrally fl attened. Dorsally with two lateral grooves and one median groove, and ventrally with two lateral grooves which can be di ffi cult to see. The reservoir is located anteriorly in the left side of the cell and is roundish. The anterior fl agellum is about the length of the cell and the posterior fl agellum is about 1.5-2 times the length of the cell. The ingestion organelle reaches almost to the posterior end of the cell. Rarely observed. Observations based on six cells. Remarks. This species was fi rst described by Larsen and Patterson (1990) from Brazil and cell length was previously reported to be 10-12 Mm. Ploeotia discoides resembles P. tenuis in having three longitudinal dorsal grooves, but it is distinguished by its lack of ventral grooves, fl atness, roundish reservoir, and by its smaller size (Larsen and Patterson, 1990). The ventral grooves are very hard to see and may be absent in some cells. The differences between P. discoides and P. tenuis are not great and future work may demonstrate that there is no unambiguous discontinuity between the two taxa.Published as part of Lee, Won Je & Patterson, David J., 2000, Heterotrophic flagellates (Protista) from marine sediments of Botany Bay, Australia, pp. 483-562 in Journal of Natural History 34 on pages 527-52
