Size: To about 50 mm. 



Least depth of capture: At surface at night. 



Distribution: Probably circumglobal between 30° and 40° S. The localities of the few 

 specimens examined in this study are shown in Fig. 72. Craddock and Mead (1970) reported (as 

 questionable) 172 specimens (21-49 mm) from the southeastern Pacific Ocean between about 

 3 1° and 34° S, west of 77° W. I have seen one specimen (25 mm SL) from 25° S, 155° W. 



Gonichthys venetus 



Becker, 1964 



Description 



D. 11 (10-12); A. 20 (19-21); P. 14 (13-16); AO 5-6 (4-7) + 12 (10-14), total 18 (16-19); gill 

 rakers (including rudiments) 4 (3-5) +1 + 8 (6-9), total 13 (11-14); vertebrae 40-41. 



Lateral line incomplete, the last 3 or 4 scales not perforated (see discussion below). 

 Greatest body depth at vertical of pectoral origin, rather than at dorsal origin. 



Size: To about 40 mm. 



Least depth of capture: At surface at night. 



Distribution: Known from northerly of New Zealand and from about 20°-30° S, 80°-110° W 

 (Fig. 72). A possible subspecies (see below) occurs in equatorial waters south and southeasterly 

 of Hawaii (designated by solid squares in Fig. 72). 



Gonichthys cocco 



(Cocco, 1829) 



Description 



D. 11-12; A. 20 (19-21); P. 13 (11-14); AO 6 (5-7) + 12-13 (11-14), total 18 (17-19); gill 

 rakers (including all rudiments) 4-5 (6) + 1 + 7 (6), total 12 (11-13); vertebrae 40-41. 



Lateral line incomplete, the last perforated scale lying under, or slightly before or behind, 

 base of adipose fin. Five to 6 AOp over anal base. 



Size: To 36 mm. 



Least depth of capture: At surface at night. 



Distribution and discussion: The placing of G. cocco, known primarily from the North 

 Atlantic Ocean, in the southeastern Pacific Ocean is based principally on the finding of 36 

 specimens from five localities (Fig. 72) that have the first externally visible lateral line pore 

 (and perforated scale) before a vertical from origin of adipose fin, a diagnostic character cited 

 by Bolin (1959) and Becker (1964a). In general, the counts for the southeastern Pacific speci- 

 mens agree well with those giv€n by Bolin for the North Atlantic specimens, except that the 

 numbers of rays in the anal fin average 2 less in the southeastern Pacific, and are similar to 

 the count for G. venetus (see above).
