This is a very interesting section of the planorbular Cyclopnori, unit- 

 ing the JSIyxostoma type with the turbinate Lagocheilus. The canal of 

 Cataulus is merely, it would seem, a more highly developed and specialised 

 rej)resentation of the shallow groove in this species.

It has been suggested that this is nothing more than the young of 

 Cataulus Galcadensis, numerous specimens of which were forwarded to me 

 at the same time, but it differs from the young of that species when of the 

 same size, as was seen from numerous examples. Two specimens only of 

 the present form were found, both dead shells, but in fair condition. The 

 form of the mouth is peculiar and the silky lustre of the epidermis also.

The nearest ally of this interesting form is 8. Avanun, W. Bl., which 

 it approaches in the recurved form of its sutural tube, but it differs in size 

 and mode of colouration. In S. Avanum, too, the linguiform projection of
