4 Mr. E. A. Smith on Mollusca from the 



that I regret having to return it to the Indian Museum at 

 Calcutta. On comparing this species with A. modestum of 

 Reeve, with which it has been united, there seem to be 

 sufficient differences to warrant their separation. The 

 sculpture on the base of the last whorl is much finer in 

 A. modestum, and the groove in the umbilical region of 

 A. girgyllus is absent in the Japanese form. There are also 

 differences of colour.
