BMNH 1916.3.20.29, 35 mm TL, 77°15' S, 166°00' E, McMurdo Sound, R / V Terra Nova , Stn. 332, 16 January 1912, 0–550 m. Material examined . NMNZ P.043482, ripe female, 69 mm TL, 61 mm SL, 76°46.02' S, 167°49.75' E, S. of Franklin Is., Ross Sea, R / V Tangaroa , Stn. IPY / CAML TAN 0802 /070, 15 February 2008, 724– 754 m. Diagnosis . (Slightly modified from Andriashev, 2003). V 51–55 (8–9+43–46), P 12–16, radials 2 (1+0+0+1). No teeth in either jaw; pharyngeal teeth absent. All gill rakers black speckled. Orobranchial cavity dark (blackish speckled), peritoneum and anterior part of stomach black. Head 24–26%, preanal length 36–40% SL. Distribution. Circumantarctic at depths from 5– 850 m. Comparisons . This species is unique among all other known Southern Ocean species in its lack of dentition. If this is noted in examination, it cannot be mistaken for any other known species. In addition, Andriashev (2003:381) noted that its pattern of radial arrangement is not that of a Paraliparis (2+0+1), but rather of a Careproctus (1+0+0+1); this, in combination with the absence of a ventral sucking disk, is also uniquely diagnostic. However, the figure of the pectoral girdle (Fig. 75 herein) included by Andriashev (op. cit.) shows three radials; R3 is small and not mentioned in the figure legend (Fig. 203). In the text (2003:382) Andriashev states that pectoral girdles of ten specimens were studied, and of those, three were anomalous, and the girdle illustrated, from paratype ZIN 46830, is one of those. In the original description of P. edentatus it was incorrectly thought to be normal and thus included in the figure (Andriashev, 1986:Fig. 30). Duhamel et al. (2010) synonymized Edentoliparis with Paraliparis on the basis of genetic data. : Published as part of Stein, David L., 2012, Snailfishes (Family Liparidae) of the Ross Sea, Antarctica, and Closely Adjacent Waters 3285, pp. 1-120 in Zootaxa 3285 on page 107, DOI: 10.5281/zenodo.283120 : {"references": ["Regan, C.
