the mouth. In the male a well-developed crest on the occiput, and 

 a fringed tentacle above the orbit twice as long as the eye ; another 

 short one at the anterior nostril. In the female no crest on the 

 neck, a fringed tentacle about as long as the eye above the orbit, 

 and another short one at the anterior nostril. Teeth, canines absent. 

 Fins : the anterior portion of the dorsal fin much lower than the 

 posterior, the two parts being divided by a deep notch ; this fin is 

 not continuous with the caudal, which last is cut square. All the 

 fin-rays simple, except those in the caudal. Colours : in the male, 

 olive-brown with indistinct blackish blotches along the side and 

 extending on to the dorsal fin ; two or three rows of round blue 

 spots on the body and head : in the female, olive-brown becoming 

 white below, and marbled all over with brown lines, forming large 

 insulated places. Head and upper two thirds of the body dotted 

 with light blue ; fins yellowish, dorsal and anal horizontally and 

 sinuously banded in spots ; caudal with five or six vertical dark bands. 

 A brown band divided by a light blue line at the base of the pectoral, 

 which is yellowish and barred with brown. 



Hab. Kurrachee. Many specimens taken at the oyster-rocks, 

 the males up to 5g, females to 4| inches in length. 



Although this species is not of a uniform brown colour, it appears 

 to agree with the original specimens, which were evidently females. 



Salarias lineatus, Cuv. & Val. 



I have recently obtained two fine female specimens of this species, 

 with the following fin-rays : — 



in one, D. j y A. 25 ; 



in the other, D. if. A. 23. 



They agree in every respect with the male, except in not having 

 any crest on the head. 



Amongst the little-known Burmese Siluroids are the two fol-

Length of head nearly ^, of pectoral ^, of caudal £, height of body

 from end of snout, 1 \ apart. Snout projecting. Longitudinal groove 

 on the summit of the head indistinct, but extending to the base of 

 the occipital process, which is narrow and has a separate interneural 

 shield between it and the basal bone of the dorsal fin ; it is twice as 

 long as wide. Barbels : the maxillary, which are the longest, only 

 reach to the anterior margin of the orbit. Teeth on the palate in 

 an uninterrupted band. Fins : dorsal spine moderately strong, 

 slightly serrated posteriorly in its upper fourth, and as long as from 

 the hind edge of the orbit to the end of the snout ; pectoral spine 

 slightly longer and stronger than that of the dorsal, and coarsely
