This species appears to breed freely in the main area of the lake as young 

 specimens are numerous. 



Distribution : — Tropical parts of the Indian Ocean.

No specimen of this species appears to have been collected but many were 

 observed in the course of the survey. Dr. Annandale tells me that the species is 

 very common in February in the shallows near the outer shore of the south end of 

 the main area of the lake, where it moves about in shoals, occasionally leaping out of 

 the water. The back is brown and is banded with five or six narrow bands of lighter 

 colour which are conspicuous in life and can be seen when the fish is several inches 

 below the surface of the water. 



The species is a permanent inhabitant in the main area of the lake. 



Distribution: — Seas of India, Bast Indies and Japan.

There are altogether nine specimens in the collection ; one is from the main area 

 of the lake off Balugaon (6-UÏ-1914), while the other eight were bought from a fisher- 

 man at Rambha on January ist, 1915. 



All these specimens have the lower jaw within the upper jaw and the teeth 011 

 the tip of the former entirely exposed (text-figs. 1 and 2) : thus the entire collec- 

 tion falls into the ' saurus group ' , and not into the ' machuata group ' of the 

 genus.
