C. testa ovato-ventricosa ; spira brevi ; anfractibus postice 

 angulatis; costis validis, distantibus, ad anguluin acute tubercu- 

 latis; lineis elevatis spiralibus; sutura profunde canaliculata ; 

 apertura magna, la3vi : columella grauulata, obtuse triplicata. 

 Colore fulvo, albo prope medium anfractuura cincto. 



From Japan, a ventricose shell, with broad, distant ribs crossed 

 by narrow spiral ribs or strise. The whorls are angular and the 

 suture canaliculated, the ribs tuberculated at the angle of the 

 whorls. It is of a pale fawn or yellow colour with a white band 

 near the centre of the whorls. The shell figured by Kiener as 

 the same species, under Michelin^s name of C. hnperialis may be 

 really the same, but it has no canal at the suture. Nor does 

 Kiener inform us why, supposing the species to be the same, he 

 does not adopt the name first published. Miclielin^s shell resembles 

 our Cassidiformis.
