Lenrrth of head 5^ to 5i, of caudal fin 4| to 5, hei^'ht of body 7 to 7| in the total length. 

 Eyes — diameter 2J in the length of the head, f of a diameter from the end of the snout, 

 and rather more than 1 apart. Interorbital space flat or rather concave. Barbels — 

 absent. Teeth — rudimentary. Fiii^ — dorsal commences between the hind edge of the 

 orbit and the end of the lower caudal lobe, anteriorly it is two-thirds as high as the body. 

 Ventrals commence midway between the hind edge of the eye and the base of the caudal 

 fin, reaching to the end of the base of the anal. Anal begins on a line below the 

 middle of the dorsal fin. Scales — 28 rows between the occiput and the base of the dorsal 

 fin. Colours — bluish, becoming silvery along the abdomen : pectoral nearly black with 

 the first ray white, and an oblique wide white band crossing from its outer edge to a little 

 in front of its base. In one specimen the ventral is black tipped : caudal grayish. 



Sahitat. — Two specimens up to IH inches long received from Bombay: it extends to the 

 Malay Archipelago.

Cirrhina afijhana, Gijnther, Trans. Linn. Soc. 1887. 



Not only does this fish differ from those of the genns Cirrhina in the character of its 

 mouth, but it Likewise possesses a serrated osseous ray in the dorsal fin.

This species is found in Ceylon, according to Haly. 



Page 582. Add Gen\i^—Acanthonotus, Tickell (MSS.). 



Mouth arched, anterior : barbels absent, eyes without adipose lids. Dorsal Jin rather short, 

 commencing slightly anterior to the root of the ventral, its osseous ray being strong, serrated 

 and preceded at its base by a small forwardly-directed spine : anal short. Scales large, 

 no enlarged row at base of anal Jin. Lateral-line complete and continued to opposite the 

 centre of the base of the caudal.

Length of head as delineated 6, of caudal fin 3j, height of body 3^ in the total length. 

 Eyes — diameter 3j in the length of the head, 1 diameter from the end of the snout. 

 Snout blunt, rather overhanging the mouth, body compressed : profile with a considerable 

 rise from snout to base of dorsal fin. Fins — dorsal spine strong and posteriorly 

 serrated, caudal deeply forked, its lobes acutely pointed. A small horizontal spine in 

 front of the dorsal fin pointing forwards and scarcely protruding from beneath the skin. 

 Lateral-line — complete. Colours — brilliant silvery with lilac and blue shades and a 

 tinge of olive-yellow on the back. Dorsal fin orange-scarlet superiorly bordered with 

 black except on the last two rays, the other fins lemon-yellow. Dorsal ridge black in its 

 upper portion. 



Habitat. — Very common in the streams of the intei . jr of the Tenasserim district, the 

 largest obtained being about 5'4 inches in length.

Length of head b\, of caudal fin 4^, height of body 3 in the total length. Eyes— 

 diameter 3 in the length of the head, 1 diameter from the end of the snout and also apart. 

 Profile over nape slightly concave, a considei-able rise from snout to base of dorsal fin : 

 snout somewhat obtuse, upper jaw the longer. Fins — dorsal anteriorly two-thirds as high 

 as the body below it, commencing somewhat nearer the snout than the base of the caudal
