(Plates XVII— XIX.) 



Baikuda is an island situated in the Ganjani District of the 

 ]>Iadras Presidency in the southern part of the Chilka Lake. Its 

 general features have been described by Annandale {Mem. As. Soc. 

 Beng. VII, No. 4 in the press). Its fauna is not a rich one, a fact 

 which facilitates detailed biological work ; and a careful study of 

 its spiders has revealed manj- features of interest. The scorpions 

 have been less fully studied.
