times in the lengtli of the head. The interorbital width is slightly 

 less than half the length of the head, and the width of the mouth is 

 nearly two and a half times the length of the head. The edge of the 

 rostral flap is entire ; on it as well as all over the snout there are 

 numerous conical warts with pointed denticles. There is a narrow 

 groove in front of the paired nostrils, the anterior nostril being 

 fleshy and tubular. There are four barbels ; those of the rostral pair 

 are longer than half the diameter of the eye ; those of the maxil- 

 lary pair are partially concealed by the over-turned lower lip and 

 are three-fourths of the diameter of the e5'e Both the lips are 

 overturned to form a suctorial disk, the lower lip being more 

 broken up. The margin of the lower jaw is mounted with a hard 

 horny covering and there is a narrow transverse groove at 

 the anterior edge of the opercle in the lower three-fourths. 

 Dorsal V 7. The first two spines are very small, almost like 

 scales ; the last spine is the longest and is less than the length of 

 the head by one length of the diameter of the eye. It is strongly 

 serrated with a double row of thirt}^ teeth in each series. The upper 

 edge of the dorsal is cut almost straight ; it is equidistant between 

 the anterior orbital and the root of the caudal; in front of it 

 there are sixty-four scales. The pectoral is less than two-thirds 

 of the distance between the bases of the pectoral and ventral, 

 and is slightly shorter than the length of the dorsal. The length 

 of the ventral is equal to five-sixths of the interval between the 

 bases of the ventral and anal. Anal II 5. The first branched ray 

 is the longest ; it is as long as the ventral and does not reach the 

 root of the caudal. The caudal is deeply divided, and the caudal 

 peduncle is one and a one-third times as long as deep. The head 

 is smooth and the portion of the bod}^ behind the opercle and below 

 the lateral line is scaleless and smooth down to half the length of 

 the pectoral fin. The scales are minute and thickset over the rest 

 of the body, those over the sheath enclosing the vent and the 

 base of the anal being one and a half times as large as those in the 

 middle of the body. There are 113 scales in the lateral line, 

 ^ in the transverse series, 14 between the lateral line and the 

 ventral fin, and 42 round the caudal peduncle. 



Colour. — The head and scaleless portion of the lower part of 

 the side just behind the opercle are bluish grey, the rest of the 

 body black with a deep bluish tint. The ventral and lower side 

 of the paired fins is dull white, the rest of the fins grey with 

 irregular dark blotches on the caudal. 



One specimen numbered F. ^^ in the Museum register, 

 measuring 202 mm. with the caudal, from Yembung, iioo ft., 

 collected by Mr. S. W. Kemp. The species is named after Captain 

 A. L. M. Molesworth of the 8th Gurkha Rifles.
