Infracaudal luminous glands of females from the eastern Pacific appear to differ consider- 

 ably from those of North Atlantic specimens. Those from the eastern Pacific bear no more than 

 4 small scales, 2 in line on each side of the median in the space between last AOp and first Pre; 

 this pattern differs notably from the cluster of 7 scales shown for the North Atlantic form by 

 Nafpaktitis (1968, p. 14, fig. 4A). The supracaudal glands of males from both oceans are quite 

 similar. 



Size: To 48 mm (largest of 60 specimens). 



Least depth of capture: All specimens before me were taken in tows to 500 m or more. 



Distribution: This species is apparently confined to the extreme southeastern Pacific 

 Ocean (Fig. 81). I have seen no other specimen among thousands of diaphid fishes from other 

 areas of the Pacific. Craddock and Mead (1970) reported the capture of 120 specimens in the 

 southeastern area at about 31°-34° S, 88°-93° W.
