and somewhat noduled ; below the band are three granular ridges 

 with pricked interstices ; lower part of body-whorl striate. 



Length, 1-75 inches. 



Hab. unknown. 



Described from a unique specimen.

Orange-colored, with two white bands of tubercles below the 

 suture, balance of the surface punctate, grooved. Length, 1 inch.

Fulvous white or straw-color, narrow, whorls numerous, flatly 

 concave, spirally ridged, sometimes decussated by longitudinal 

 sculpture, with two bands of nodules below the suture, and a 

 single smaller row on the periphery of the last whorl. 



Length, 2-4 inches. 



Philippines (Cuming), Port Curtis, Australia (Stutchbury). 



The latter locality is for T. prselonga, Desh. (fig. 57), which 

 does not appear to me to differ. 



C. No sutural band, closely striate or plicate next the suture; 

 balance of whorl smooth or plicate. 



T. C^RULESCENS, Lam. PI. 10, figs. 75-77 ; PL 9, fig. 66. 



Shell smooth, without infra-sutural band, but usually with a 

 narrow callous deposit forming a more or less defined band above 

 the narrow sutural groove; whitish, spotted or clouded with 

 chocolate below the suture, the clouds sometimes forming a wide

 extending to the base ; when well covered with chocolate there 

 is often a lighter band upon the periphery. 



Length, 1-5-2-5 inches. 



Australia; Philippines; Polynesia; Mauritius ; Red Sea. 



The whorls are flattened, and scarcely impressed at the sutures. 

 This species is the type of Mr. E. A. Smith's subgenus Impages, 

 characterized by the callous deposit above the sutures ; but this 

 peculiarity is not even constant in this species, and is rare or not
