 Reeve, can scarcely be distinguished from that of Mappa, Sow.,

We have received specimens of nanus from the locality at 

 which it was collected by Mr. Cuming. It also occurs at the 

 Hawaiian Islands, and all localities in Polynesia where the pu- 

 sillus or Ceylonensis are found, being a colorless variety. It may 

 be distinguished from a colorless variety of sponsalis by its epi- 

 dermis. On the opposite extreme, the shell is nearly wholly 

 colored with reddish-brown, relieved by a few white spots or 

 lines. From this variation it passes into Ceylonensis, as figured by 

 Reeve and Kiener, on which the transverse interrupted lines ap- 

 pear ; when the lines cover the whole surface, it becomes the pusil- 

 lus, Chem. Occasionally the lines are arranged longitudinally. 

 Very rarely the whole surface is granulose, and it is more highly 

 turreted than the specimen figured by Kiener. 



The animals of the species above agree ; white proboscis, both 

 extremities of the foot and end of the siphon pink. 



At some localities on the Hawaiian Islands it is common, 

 lurking under stones at low water mark.
