cleft obliquely ascending ; the length of the maxilla is one 
third that of the head ; a narrow band (?) of small teeth in 
each jaw and on the vomer; tongue large; only the floor of 
the mouth pigmented. 
Gills ; gill-opening a small circular aperture just beneath 
the root of the pectoral fin. 
Skin thin and perfectly smooth and scaleless ; it is pro- 
tected by a thick coat of mucus. 
Two clavate cephalic tentacles, the first being rather more 
than twice the length of the second, situated close together 
immediately behind the interorbital space, with luminous 
organs imbedded in their enlarged tips. Second dorsal and 
anal placed far back on the tail, almost in contact with the 
caudal, which is pointed and in length a little more than one 
fourth of the total ; all the rays of the vertical fins simple ; 
pectorals very short, pointed ; ventrals absent. 
Colours : — Body and fins jet-black ; in spirit the tip of the 
cephalic tentacles become white. Pharyngo-branchial and

About forty specimens from Station 96 (98-102 fathoms), 
many of them being females with mature ovaries. It is 
remarkable that the largest specimen barely reaches a length 
of 7 inches. 
The original description of the vomerine teeth is Cc il n’en 
existe qu’un petit tas, n and in these Indian specimens the 
vomerine teeth are inconspicuous, obsolescent, or even in some 
cases absent. The intestine is long and convoluted, and there 
are five large pyloric caeca. The stomachs of the dissected 
specimens contained Scopeli. 
Colours in the fresh state : — Head pink, dorsal half of body 
pink, with large scattered black spots, ventral half silvery 
white ; pectoral interradial membrane dark olive-green, pec- 
toral appendages and ventrals pink ; first dorsal fin with a 
large black patch from second to sixth spines ; second dorsal 
with a longitudinal row of black spots.
