is distinguished from its congeners by the following combination of characters: pelvic fins present or (rarely) absent; branchiostegal rays 6; no occipital pores; lateral line with ventral and mediolateral branches, ventral originating behind posteriormost postorbital pore, mediolateral originating on vertical through pectoral fin margin or somewhat anterior to margin when fin appressed; gill rakers blunt and triangular except in specimens over about 320 mm SL; vertebrae 20-27 + 71-86 = 92-113.

Remarks. This species was thoroughly redescribed on the basis of 76 specimens, including four syntypes, by Anderson (1988). All of these possessed the typical, rudimentary pelvic fins of most zoarcids. The new Weddell and Ross seas material adds no further data except the following: Pelvic fins are absent in RUSI 54819, MNHN 1990-635, one (105 mm SL) in ISH 16/91, 28 in RUSI 54825 and one (217 mm SL) in RUSI 54821. The other in ISH 16/91, ISH 9/91, MNHN 1990-633, 1990-634, two (205, 214 mm SL) in RUSI 54821 and four (202-228 mm SL) in RUSI 54825 have regressed, nipple-like pelvic fins as described for
