Remarks and additions to description. The new species herein described, Exogone yagan, share the lack of spiniger-like chaetae with E. anomalochaeta, an Antarctic species. For this reason, we examined specimens deposited in the MNCNM, collected and reported by San Martín & Parapar (1997). These specimens agree with the previous descriptions, except for the absence of dorsal cirri on chaetiger 2 (Figs 4A, 5A); this character is described in the previous descriptions but in Benham 1921, fig. 11, the drawing shows dorsal cirri on chaetiger 2; at that time, the importance of the presence or absence of dorsal cirri on chaetiger 2 was not known to separate species of Exogone, and usually they were figured although not present. The compound chaetae are all thick, with distally enlarged shafts and numerous distal and subdistal spines (Figs 4C, E, G), and very short, almost included inside the distal, spinose part of the shafts, named as “gomphotric chaetae” by Benham 1921, 1927. The dorsal simple chaetae are the typical of the genus (Figs 4B, F, 5B, C, E), but some in the mid-body are distally enlarged, and having a spatulate appearance (Fig. 4D). Apparently, this species lacks ventral simple chaetae, since they have not been described by any author and we have not found these in the material examined. Barroso et al. (2017) recently redescribed this species in bases of material collected in Brazil between 749 and 1050 m depth. These specimens agree well with the Antarctic specimens, except by having ventral simple chaetae and longer proventricle (3.5–5 segments instead of 2–3 segments); it is possible that they could belong to two different species, but would be necessary more detailed studies to separate them.

Ocular dominance and subjective color perception: a study using the Fechner-Benham Visual Illusion
No full textPast research has demonstrated differences in visual processing between the dominant, or preferred eye, and the non-dominant, or less preferred eye. Researchers have accounted for these differences according to either physiological mechanisms (Porac & Coren, 1976) or behavioral preferences (Mapp, Ono, & Barbeito, 2003). The behavioral preferences account can be eliminated by examining how the eyes process visual illusions which are not expected to be influenced by prior experiences. One particular illusion, the Fechner-Benham Color Illusion, involves disks featuring black and white designs which, when rotated, produce the illusion of various subjective colors within the disks (Rosenblum, Anderson, & Purple, 1981). It was hypothesized that when viewing the Fechner-Benham Illusion with the nondominant eye, participants would exhibit longer latencies for the onset of color andwould report fewer colors compared to viewing with the dominant eye and with binocular vision. The underlying physiological mechanisms that are often regarded in subjective color perception are either described high in the visual information hierarchy, in a neurophysiological site, thus eliminating the retinal level (Rhollec & Vi�not, 1999;Robinson, 1896). Or, antagonistically, they are described as taking place within theretina in terms of an uneven distribution of photoreceptor cells (Jarvis, 1977).College Honors

Polycirrus hamiltoni Benham. Smallest 1921
No full textPolycirrus hamiltoni Benham, 1921 Fig. 29a–f Polycirrus hamiltoni Benham, 1921: 94, pl. 9, fig. 101–106. Type locality. Macquarie Island, Antarctica. Material examined. SYNTYPES: 3, AM W611, Australian Antarctic Expedition, Australia, Macquarie Island, Garden Bay, intertidal 54°30ʹ S, 158°57ʹ E (smallest syntype illustrated here). Additional material examined. 8 specimens, AM W824, Australia, Macquarie Island, 54°30ʹ S, 158°57ʹ E. Description. Syntypes mainly well preserved with body wall intact, yellowish in colour, 2 complete and 1 incomplete individuals forming type series. Complete individuals 10 mm long (without tentacles), 1 mm wide for 50 segments and 15 mm long (without tentacles) and 1.2 mm wide for 65 segments. Posteriorly incomplete specimen (illustrated here and separated in a microvial from other syntypes) 10 mm long (without tentacles which are missing) and 1 mm wide for 37 segments. Dorsum anteriorly tessellated. Venter anteriorly with mid-ventral groove and discrete ventro-lateral pads; pads more-or-less smooth, extending from segment 3 to 12. Mid-ventral groove from segment 2 (Fig. 29a). Buccal tentacles numerous of two types, (1) cylindrical, thickened distally and distinctly grooved and (2) cylindrical, uniformly thin and weakly grooved, both arising at junction between prostomium and upper lip. Prostomial ridge distinctly curved, extending laterally along anterodorsal base of upper lip. Upper lip trefoiled with lateral blindly-ending enclosed diverticula, margin of medial lobe convoluted (slightly); oral surface glandular, ciliated, with grooves leading to mouth. Inner lower lip oblong, raised, ridged; outer region flat, shield-like, subtriangular and pointing toward mouth, ridged and grooved, extending posteriorly to segment 3. Achaetous segments visible dorsally but obscured by expanded outer lower lip ventrally. Notochaetigerous segments 30–34, extending to segments 32–36. Notopodia digitiform anteriorly and moreor-less rectangular posteriorly, prechaetal lobe low, postchaetal lobe digitiform, longer than prechaetal initially, though lobes becoming equal posteriorly (Fig. 29b). Notochaetae within a chaetiger consisting of two types (chaetigers 4, 16 examined), hirsute, subdistally expanded (slightly), posteriorly same form as those anteriorly; secondary notochaetae in all chaetigers pinnate (Fig. 29c, d). Neurochaetae beginning on segment 9. Neuropodial tori erect pinnules, differ along body (uncini arranged in C-shaped row in posterior tori). Uncini with short neck and straight to convex base (Type 1), teeth above main fang arranged in double transverse series (MF:1:∞) enlarged median tooth above main fang present, subrostral process absent (Fig. 29e, f). Nephridial papillae present, globular. Pre-gular membrane nephridial papillae present on segment 4 only. Postgular membrane nephridial papillae present, extending from segment 5 to 8; situated at ventral base of notopodia (Fig. 29a). Pygidium simple rosette. Comments. The specimens described here and labelled as syntypes are not the same as those described by Benham (1921). The size and chaetiger numbers do not match. Further, Benham states in his original description that one of the specimens is a mature female, whereas (AM W611) contains two mature males; however, in all other respects the material fits Benham's description and is accepted here as representing syntype material. It is likely that the syntypes were designated after Benham (1921) described the species P. hamiltoni.Published as part of Glasby, Christopher J. & Hutchings, Pat, 2014, Revision of the taxonomy of Polycirrus Grube, 1850 (Annelida: Terebellida: Polycirridae), pp. 1-117 in Zootaxa 3877 (1) on pages 58-60, DOI: 10.11646/zootaxa.3877.1.1, http://zenodo.org/record/494837
Chunk and permeate III: the Dirac delta function
