The genus Euplecta was pi'oposed by Semper 1 with two Ceylonese 

 species, E. subopaca and E. Layardi, as types. It has now been 

 shown by Godwin-Austen to comprise several Ceylon species, and 

 there can be little, if any, doubt that other forms from the hills of 

 Southern India must be added. Anatomically the genus is only 

 shown to be distinguished from Ariophanta by a peculiar feature of 

 the genitalia, but the shell is, as a rule, more closely wound, and the 

 animal is consequently more elongate. Nearly all the species have 

 keeled shells, and many of them are distinguished by a peculiar 

 decussated sculpture, which in a few forms becomes almost hie-like. 



The following is a list of the species referred for the present to 

 Euplecta : —
