(8) Body, head, and bases of fins covered with small scales, of which there 

 are about twenty-seven rows between the dorsal fin and the vent. Lateral line 

 very indistinct, apparently not continued halfway along the tail. 



(9) Dorsal and anal fins confluent with the caudal : the longest dorsal rays 

 are about two-fifths the greatest body height. 



(10) The distance of the 1st anal ray from the base of the pectoral is 

 slightly more than the length of the head. 



(11) Each pectoral consists of two portions, — a normal, pointed, upper 

 portion which is a little longer than the head, and a lower portion consisting of 

 eight or nine free filamentous rays the longest of which (2nd and 3rd) are 



from l| times to twice the length of the head. 



(12) Each ventral consists of two entirely separate rays, the inner and 

 lono"er of which is equal to the length of the head behind the middle of the eye. 



(13) There are a few extremely short almost rudimentary pyloric caeca. 

 Colours in spirit, yellowish brown : gill-membranes, pectoral fins and their 



free filaments, ventrals, and outer part of dorsal and anal fins, black. 



The largest specimen is 10 inches long. 



In the Indian Museum are 4 specimens from the Andaman Sea, 669 fathoms, 

 and the Arabian Sea, 406 and 740 fathoms, (besides a specimen from the Atlantic, 

 presented by the Smithsonian Institution). 



Distribution : West Indies and Atlantic coasts of the United States : Atlantic 

 coasts of Morocco and north-west Africa: Arabian Sea. At considerable depths.

Differs from Dicrolene intronigra only in the following particulars, which 

 are numbered to correspond with the paragraphs relating to the diagnosis of 

 that species : — 



(1) The length of the head is about two-ninths of the total. 



(4) The major diameter of the eye is not quite two-ninths the length of 

 the head. 



(8) Scales in 34 or 3-5 rows between the dorsal fin , and the vent: the 

 lateral line ends in the last third of the tail. 



(10) The distance of the 1st anal ray from the base of the pectoral is 

 equal to the length of the head without the snout.
