REPORT ON THE GASTEROPODA. 393 



This is a very exceptional form, and there is nothing much resembling it for comparison. It is 

 narrower in the spire, less strongly ribbed longitudinally, with a shallower suture and much longer 

 snout than Triton qiwyi, Reeve = Triton viperinum, Kiener nee Lam., which in some features it recalls.
