Eyes almost in contact, the upper slightly in advance of the 

 lower, which is on the lip ; their major diameter is more than 

 one sixth the head-length. On the coloured side only one 

 nostril, in the form of a rather long slender tube situated in 

 front of the lower eye ; on the blind side two, the anterior of 

 which is a short tube. 



Mouth small, its angle nearer to the tip of the snout than 

 to the gill-opening. Scales ctenoid on both sides. Two 

 lateral lines on the coloured side, which branch and anasto- 

 mose on the head; the upper, which ends immediately behind 

 the vertical through the middle of the body, is separated from 

 tlie lower, which is continuous to the base of the caudal, by 

 ten rows of scales. No lateral line on the blind side. One 

 ventral tin united to the. anal by a broad membrane. The 

 highest [middle] dorsal and anal rays considerably exceed 

 the length of the snout. 



Colours in life : — Left side uniform sepia-brown. 



Length nearly 5 inches. Two specimens. 



Off Ganjam coast, 33 fathoms ; bottom sand. 



These two species are closely allied, both belonging to the 

 subgenus TruUa^ Kaup.
