The short spire, with obtuse apex, the depression of the last whorl 

 round the narrow umbilicus, the bent columella, and the thick somewhat 

 eroded texture, o£ a greenish colour unusual in the genus, are the best 

 characteristics of this small species, for which I am indebted to my friend 

 Surgeon-Major R. Hungerford ; I have named it after my esteemed 

 correspondent Dr. Henry Dohrn of Stettin.

I have named this pretty and very distinct species after my friend 

 Mr. J. Wood-Mason, to whose very successful researches in the Sunder- 

 bunds the Museum is indebted for so many interesting moUusks, as I have 

 already pointed out in my Catalogue, Fasc. E, p. 22, when describing the 

 operculum of Larina burmana. The small, almost obsolete, keel round the 

 very minute perforation (which is sometimes completely covered) is very 

 characteristic. 



Mr. Wood-Mason has favoured me with the following extract from 

 his note-book on the animal of this species — " Eyes large, intensely black, 

 situated on the upper side and near the extremity of the peduncle ; animal 

 transparent, above very slightly greyish, between the tentacles reddish, 

 which are so transparent that the eye-spots can be seen very nearly as well 

 from the under side."
