Between the 11th November, 1889, and the 25th March, 
1890, the L Investigator ’ trawled, on occasion, in shallow 
water off the south-east coast of Ceylon (82 fathoms) , off the 
east coast of the Andaman chain and in the Gulf of Martaban 
(20 to 41 fathoms), and systematically along the east coast of 
the Indian peninsula between lats. 17° 50' and 19° 50' N. 
in depths ranging from 7 to 102 fathoms. 
In the class of Fishes numerous forms previously unnoticed 
in the Indian fauna and also forms apparently hitherto 
undescribed were taken ; and the present paper is devoted to

fathom line. Of these there are thirteen species to notice,
