KALIELLA. 265 



Probably introduced, like other shells of those islands, from the 

 Malabar coast. 

 The teeth of the radula number : 



32 . 6 . 1 . 6 . 32 (38 . 1 . 38). 



The adtnedian teeth, like the rhachidian, have a long median cusp 

 and lateral cusps as in K. barrakjporensis, &c. [The internal 

 anatomy has not been seen, it therefore can only be placed in 

 this genus with doubt.]
