Gymnoscopelus (Gymnoscopelus) nichoisi 



(Gilbert, 1911) 



Fig. 196 — Gymoscopelus (G.) nichoisi, 141.0 mm. From Andriashev (1962, p. 270, 



fig. 32). 



Description 



D. 18 (17-19); A. 19-20; P. 13-14; AO 10 (9-11) + 7 (6-9), total 17-18 (19); gill rakers 10-11 

 + 1 + 21-24, total 32-36; vertebrae 43-44 (42-45). 



Photophores relatively large, light in color. PLO about midway between lateral line and 

 pectoral origin; VLO 1.0 to 1.5 times nearer pelvic origin than to lateral line. A line through 

 PV0,.2 passes well behind PO^, nearly through PO.^. Six PO, the last notably elevated, the 

 rest on same level; 5 (4 or 6) VO, none elevated. SAO series straight or in slightly obtuse angle. 

 SAOi.2 interspace slightly less than that of SA02..i. SAO, nearly on level of last VO. AOp-Prc 

 series usually continuous, except when 9 Pre are present. 



Size: To 148 mm. 



Least depth of capture: No information. 



Distribution: Antarctic waters of Pacific and Indian Oceans (about 62° to 70° S). 



Gymnoscopelus (Gymnoscopelus) bolini 



Andriashev, 1962 



Description 



Two specimens reported by Andriashev ( 1962, p. 272), the holotype (46.0 mm) and 

 paratype (33.0 mm). The counts are given in that order. 



D. 19, 21; A. 21, 21; P. about 13; AO 10 + 7-6, 12-10 + 7 (6?); gill rakers 6 + 1 + 14, 7 + 1 + 

 16, total 21-24; vertebrae 43. 



PLO nearer lateral line than to pectoral origin; VLO midway between lateral line and 

 pelvic origin. A line through PVOi.j passes through PO2. Five PO, the last elevated. Five VO,
