Gymnoscopelus (Nasolychnus) fraseri 



Fraser-Brunner, 1931 



Fig. 200 — Gymnoscopelus IN. I fraseri, holotype, 63.0 mm. From Fraser-Brunner 



(1931,p. 224, fig. 4). 



Description 



The following counts are taken from both Fraser-Brunner (1931) and Andriashev (1962). 



D. 16-18; A. 20; P. 13; AO 10 + 7; gill rakers 7-9-^1 + 17-19, total 26-28. No data 

 available on numbers of vertebrae or scales in lateral line. {Note: Fraser-Brunner listed 20 

 rays in both the dorsal and anal fins. ) 



The following description is taken from Fraser-Brunner (1931). PLO much nearer lateral 

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

 PVOi.2 form a nearly vertical line. Five PO, only the last elevated; 5 VO, none elevated. SAO 

 series in a nearly vertical, straight line; SAO, only slightly above level of last VO; SAO3 1.0 to 

 1.5 diameters below lateral line. AOp-Prc series well separated. Pre 3+1, the last widely 

 separate and elevated. 



Size: Only two sizes given, that of holotype and 6.95 mm for a questionable specimen 

 reported by Andriashev. 



Least depth of capture: A specimen from Antarctic waters, provisionally identified as G. 

 (N.) fraseri by Andriashev, was taken at surface at night; others from to 1000 m. 



Distribution: Taken mostly in Antarctic waters, but the holotype was taken in Gulf of 

 Guinea at 03°18' S, 05°17' E. 



Gymnoscopelus (Nasolychnus) piabilis 



(Whitley, 1931) 



Description 



D. 18-19; A. 18; P. 13-14; AO 7-8 + 8-9, total 15-17; gill rakers 9-10 + 1 + 18-19, total 

 28-30; vertebrae 42. (Note: In a key to identification of G. fraseri and G. piabilis (communi- 

 cated to Andriashev by Bolin) the gill rakers for G. piabilis were given as 9-10 + 1 + 19-22, 

 total 29-33.) 



PLO less than its diameter below lateral line; PLO and PVO1.2 in a nearly straight line 

 inclined somewhat forward. VLO midway between lateral line and pelvic origin. Five PO, the 

 last slightly elevated; 5 VO, the last slightly below level of rest. SAO series almost equally 

 spaced in a nearly vertical, slightly angulate line; SAO, a little above level of last VO; SAO,^ 

 its diameter below lateral line. Pre 3 (4?) + 1, the last widely separate and elevated. 



Size: To 122 mm. 



Least depth of capture: No information. The holotype was found stranded on a beach at 

 Macquarie Island (Whitley, 1931). 



Distribution: Poorly known; mostly taken in Antarctic waters.
