PUSIA. 185 



whorls dark chocolate, tessellated with white around the upper 

 part, and on the spire. Length, *5 inch. 



Habitat unknown. (Red Sea?} 



I am not acquainted with the species ; it may be a variation 

 of T.pardalis. 



T. APERTA, Sowb. PI. 55, fig. 58T. 



Slightly ribbed ; chocolate, with an irregular yellowish band. 



Length, *7 inch. 



Habitat unknown. 

 Described from a single specimen in the late Taylor collection. 



T. MILLECOSTATA, Swainson. ' PL 55, fig. 588. 



Closely, finely longitudinally ribbed, with impressed revolving 

 strife at the base ; orange yellow to dark chestnut-brown, some- 

 times with two interrupted lighter bands. Length, '5 inch. 



Island of Annaa. 



T. LUCULENTA, Reeve. PI. 55, figs. 589-594. 



Short pupae form, with obtuse apex ; or ventricose in the 

 body-whorl, with a more or less angulated periphery, and dis- 

 tantly irregularly folded or ribbed ; sometimes narrow. Color 

 alternate revolving bands of white or light yellowish and dark 

 chocolate or black. Length, '5 inch. 



Philippines ; Polynesian Islands, on coral reefs. 



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

 the t} r pical state is pupaeform 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 bands are narrow ; Sowerby has re- 

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

 narrower variety of the shell with narrow white bands Mr. 

 Sowerby calls T. Isevizonata (fig. 593). To complete the syn- 

 onymy, we m&y probably add T. tricolor, Montr, (fig. 594) in 

 which there are indistinct rufous bands in the middle of the 

 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 Montr ouzieri, that 

 of tricolor being preoccupied. Mr. Garrett remarks of this
