126 Messrs. J. Wood-Mason and A. Alcock on 



Entire body and head, including the snout, jaws, and eyes 

 up to the corneal margin, covered with small, adherent, ctenoid 

 scales ; no lateral line. 



The dorsal fin begins above the middle of the upper eje ; 

 its longest rays, which are just in advance of the middle of 

 the fin, are a'little more than two fifths of the bjdy-height in 

 length and not quite so long as the corresponding anal rays. 

 The distance from the tip of the snout to the origin of the 

 anal fin is about equal to the body-height. The length of 

 the caudal is contained about 7-^ times in the total. The 

 ventrals are separated from the anal by an interval equal to 

 the length of tlie snout. 



Colours in the fresh state : — Left side warm brown, with 

 seven complete rather broad cross bands. 



Two specimens, nearly 4 inches long, from Station 115, 

 188 to 220 fathoms.

A small specimen was taken at Station 118, in 180 5 

 fathoms ; it agrees very closely with Argyropelecus hemi- 

 gymnus, Cocco, from which it differs most conspicuously in 

 having the luminous spots in a continuous unbroken series 

 from the head almost to the base of the caudal ; the tail also 

 is not so abruptly constricted off from the abdomen. 



This, so far as I know, is the first record of Argyropelecus 

 from the Indo-Pacific.
