Squilla scorpio var. immaculata has been recorded from Karachi, from the 

 Gangetic delta and from the Arakan coast. In the vicinity of Calcutta, a locality 

 in which the typical form has never yet been found, it is far from uncommon, living 

 in water of low but variable salinity.

 A single specimen of this species, a male 77 mm. in length, was obtained by Mr. 

 T. Southwell in August, 1913, from fishermen at Satpara. The specimen was un- 

 doubtedly found in the outer channel of the lake, and if, as seems probable, the perio- 

 dic changes in salinity in 1913 were the same as those of 1914, the individual must 

 have been found in fresh water. 



We obtained no specimens during our survey of the lake and are inclined to 

 regard the species merely as a casual immigrant to the outer parts of the lake-system. 

 Squilla interrupta is common on the Orissa coast of the Bay of Bengal and is known 

 to have a distribution extending from the Persian Gulf to Formosa and Hongkong.
