The Fish Fauna of Ram'eswaram Island. 
(By EDGAR THTJESTON, Esq., Superintendent, 
Government Central Museum, Madras.) 
I MAY state at the outset that I have no new facts to add 
to the subject of South Indian Ichthyology, and my only 
excuse for reading the present notes before the Society is that 
the fish fauna of the coral reefs of Rameswaram — an island 
separated on the one hand from the Indian continent, and 
on the other from the island of Manaar, by an interrupted 
ridge of rocks known as Adam's bridge — stands out in such 
striking contrast to that of other places on the Madras coast, 
as to be, in some measure, instructive. 
The following list is a complete one of the fishes ob- 
tained during a residence of three weeks on Rameswaram 
island in the month of August 1886 : — 
SUB-CLASS. PAL^ICHTHYES. 
FAMILY. TOEPEDINIDiE (Electrical rays). 
Narcine timlei. 
SUB-CLASS. TELEOSTEI. 
Leptocephalus, sp. 
FAMILY. PEECIDiE (Perches). 
Lates calcarifer. 
Lutianus fuhiflamma. 
Diagramma crassispinum. 
Scolopsis vosmeri. 
* Apogon kalosoma. 
. Cheilodipterus quinquelineatus.
