A species of very variable form, and sculptured or smooth ; 

 the t3q3ical state is pupseform furnished with white bands as 

 wide or wider than the black ones (fig. 589) ; a more ventri- 

 cose shell with the black bands proportionately wider is T. 

 dichroa, Ad. and Reeve (fig. 590) ; a still more ventricose and 

 more usual form has been called by Mr. Crosse T. Grseffi (fig. 591); 

 it is ribbed, and the white bauds are narrow ; Sowerby has re- 

 described it under the name of T. nigrofasciata (fig. 592). A 

 narrower variety of the shell with narrow white l)ands Mr. 

 Sowerb}^ calls T. Isevizonata (fig. 593). To complete the S3'n- 

 onymy, we may probably add T. tricolor ., Montr, (fig. 594) in 

 which there are indistinct rufous bands in the middle of tlie 

 white bands ; this is not a constant character, as in a specimen 

 sent to me by M. Crosse, the rufous markings are not visible. 

 Tapparone-Canefri has changed the name to Montrouzieri, that 

 of tricolor being preoccupied. Mr. Garrett remarks of this
