It differs also in the number of scutes and in some of its proportions from the other 

 species. 



A specimen measuring ioo mm. was caught in Rambha Bay in March, 1914. 

 It is the type of the new species and is entered under number F &-Z-&£ in the register of 

 the Indian Museum. There are two co-types, one from the same locality as the type 

 measuring 95 mm., and the other (measuring 53 mm.) from off Nalbano, collected 

 on 6-iii-i4- 



The species is in all probability a permanent inhabitant in the main area and 

 breeds in the lake.

Hamilton Buchanan derived the name of the species from the generic vernacular 

 name quoted by Rüssel : Peddah Poorawah — the great purava. A pair of pear- 

 shaped black markings behind the occiput appears not to have been noticed by 

 Hamilton Buchanan who consequently remarked " No spotting. " 



There are altogether thirty-four specimens of the species in the collection. This 

 appears to be the prevailing species of the genus in the lake, occurring in all sizes, all 

 over the lake throughout the year. Probably the species breeds in the lake during the 

 rains. The statement below gives the sizes, dates and the different localities in the 

 lake from which specimens were collected.

Bleeker described a species under the impossible name E. porova (Ich. Madura,
