length of the head : two diameters apart. Gill-cleft contracted : three 

 gills. The skin is loose and glandular, and round the edge of the disk 

 and along the sides of the tail there is a scanty fringe of cutaneous 

 filaments. The dorsal spines are simple filaments, the first two of 

 which stand close together on the snout : the third is about twice 

 the length of the second and as long as the cephalic disk in the 

 after half of Avhich it arises. The second part of the spinous dorsal 

 is represented by a single filament about two eye-lengths long, arising 

 near the hinder limit of the cephalic disk. 



Colours in spirit: very dark sepia mottled with black: tongue 

 dusky. Length 4. 25 inches. 



Loc. Station 151, off Colombo, 142 to 400 fms. 



This species is very closely related to Lophius mtitilus, mihi (J. A. 

 S. B., Part II of 1893 ; and Zoology of the R. I. M. S. ' Investigator', 

 Fishes, Part II, pi. X, fig. 2), from which it chiefly differs in having the 

 second part of the spinous dorsal fin represented by a single well- 

 developed spine, instead of by two hidden rudiments.

Body remai-kably thin and depressed. The greatest leno-th of the 

 cephalic disk, which is half the total, caudal included, is only four-fifths 

 of its greatest breadth. 



The spines on the dorsal integument, with the exception of those 

 along the rostral and supra-orbital margin and those on the edo-e of the 

 disk and along each side of the tail, are mere spicules, quite different 

 from the large stellate spines of the other species ; and the ventral inte- 

 gument is thick, soft and glandular, and is absolutely smooth. The 

 cleft of the mouth is two-fifths the breadth of the wide disk. 



Eyes large, their diameter being between one-seventh and one-eio-ht 

 the length of the cephalic disk : interorbital space very slightly con- 

 cave. 



The caudal fin is half the length of the tail, or one-fourth the total, 

 itself included, and is equal in length to the pectorals : the long narrow 

 ventrals are just over two-thirds the length of the pectorals. 



Colours in spirit : upper surface smoky blue becoming hyaline 

 round the edge of the disk, under surface hyaline, finely and closely 

 speckled with silver : dorsal fin blackish : pectorals and caudal broadly 

 and darkly banded in the distal half, and often milk-white at tip : 

 numerous fine jet black filaments on the upper surface of the disk : 

 a black ring round the orbit.
