AVitb regard to tbe animal tbe author doubts the existence of 

 gills and makes the following remarks : " . . . . the large vascular 

 sac at tbe back of the neck exactly resembles tbat in the opercu- 

 iated land-shells. The mantle- margin is free, and the sexes 

 distinct. The lingual ribbon is very long; one from a large 

 specimen measured | incb (17 mill.); the teeth are 7-ranked, but 

 differ in form from those of Cyclostomaceous genera. The 

 amphibious habits of the animal, the short foot, and the olive- 

 green epidermis, so characteristic of fresh-water shells, induce uje 

 to place it in the vicinity of Lithogh/plius.''
