53G BULLIDiE. 



SCAPHANDER. Montfoiit. 



Shell ovato-pyrlform, convolute, narrowed above, ex- 

 panded below ; spire depressed ; aperture contracted above, 

 patulous below, not canaliculated. No operculum. 



Animal not investing the shell, bulky, capital disk large, 

 quadrate, lateral lobes small, foot ample but short. No 

 eyes. Gizzard of thin calcareous plates. Axis of the 

 tongue unarmed, its lateral membrane armed each with a 

 single series of uncinated teeth. 



The gizzard of Scaj)hander is a remarkable object, and 

 has more than once, when found apart from the animal, 

 been elevated to the rank of a separate genus, and con- 

 sidered as an independent mollusk. The spurious genus, 

 Gioenia, had such an origin.
