commonly taken in eastern central Pacific west of 150° W, but whether because of nonoccur- 

 rence or lack of collecting effort is not known. 



Lampanyctus omostigma 



Gilbert, 1908 



Fig. 177 — Lampanyctus omostigma, 60.0 mm. From Wisner (1963a, p. 17, fig. 2). 



Description 



D. 14 (13-15); A. 18 (16-20); P. 13 (12-14); AO 5 (4)6 + 8-9 (7-10), total 13-14 (12-15); gill 

 rakers 4 (3-5) + 1 + 10-11 (9-12), total 15-16 (13-18); vertebrae 36 (35-38). 



PLO and VLO slightly below, SAOn and upper Pol touching, lateral line. VO^ elevated and 

 displaced forward to at least its diameter before a vertical from VO,. AOa series about evenly 

 spaced, markedly curved. Last 3 Pre evenly spaced in a straight, steeply oblique line. Two or 

 three AOp over anal base. Pectoral fin usually reaches to about middle of AOa series. In- 

 fracaudal gland with 8(7-9) luminous scales, nearly filling infracaudal space. 



Size: To about 65 mm. 



Least depth of capture: At surface at night. 



Distribution: L. omostigma appears to have distribution very similar to that of L. par- 

 vicauda (Fig. 176). It is sparsely collected in the central Pacific, but the reason for the paucity 

 of occurrence is not clear.
