of the dorsal fin or further is often conspicuous. Sometimes it expands 

 into a well-defined spot at the base of the caudal. 

 Our largest specimens are 30 mm. long.

 This little fish is very abundant all over the Inle Lake (3,000 ft.), in 

 ponds and marshes in the same valley and also in streams and pools in 

 the old He-Ho lake-basin 800 feet higher. In habits it resembles 

 Sawhwfi resplendens, with which it is frequently taken. It is an even 

 more important ingredient in the dried whitebait of the local bazzars.

The greatest depth of the body is about | of the total length, the 

 length of the head the same or slightly more, the depth of the caudal 

 peduncle ^q . The eye, which is prominent, is twice as long as the 

 snout and much broader than the interorbital space. The scales are 

 very large but thin and have their sculpture obscure. The anterior 

 border of the dorsal fin is distinctly in advance of the vent and a little 

 nearer the base of the caudal than the tip of the snout. The pectoral 

 when expanded hardly reaches the base of the ventral ; the anal is 

 short, its posterior border lying nearer the vent than the base of the 

 caudal ; the caudal is forked. The scaly sheaths of the dorsal and 

 caudal are very well-developed. 



The pharyngeal bones resemble those of M. rubesc'ens in form and 

 in the large number of teeth they bear, but are relatively shorter and 

 stouter. 



Preserved specimens are of a greyish colour, darker on the back 

 than on the sides and belly, with about 12 obscure blackish vertical 

 stripes on the body and a black spot surrounded by a pale ring on the 

 caudal peduncle. The fins are colourless. In the living fish, however, 

 the whole surface is deeply suffused with scarlet, the vertical stripes 

 are blue and the ocellus on the tail is much more conspicuous. 



Our largest specimen is only 20 mm. long and even smaller examj)les 

 are fully mature.

This gorgeous little fish was taken only at the edge of the Inle Lake, 

 among the stems of decaying grass from floating islands. It is mark- 

 edly gregareous. Numerous specimens have been identified from 

 samples of dried whitebait from the market at Fort Stedman.

The habit is slender and sprat-like. The dorsal profile is higher 

 than the head but not strongly arched, the ventral profile sinuous. 

 The head is long and narrow, the snout sharply pointed. The greatest
