CANCELLARIA. 79 



C. BICOLOR, Hinds. PI. 5, fig. 86 ; PI. 6, figs. 89, 90. 



Shouldered, longitudinally distantly costate, crossed at regular 

 distances by slightly elevated lines ; aperture ridged within, 

 columella triplicate ; umbilicus large ; yellowish white, banded 

 or clouded or nearly covered with chestnut or chocolate. 



Straits of Macassar (Hinds) ; Philippines (Cuming). 



Hinds' figure (fig. 86) represents a shell only half an inch 

 long, yet in his description he states that the species is larger 

 than C. rigida, Sowb. The figures given by Reeve and Sowerby 

 are much larger than that of Hinds, and may not represent the 

 same species. Hinds' figure much resembles C. costifera, Sowb. ; 

 the others are nearly related to G. goniostoma, Sowb. 



C. STIMPSONII, Calkins. PL 5, fig. 87. 



Whorls shouldered, the angle nodulous, surface below it 

 covered with irregular nodules, which do not appear to be 

 developed in the lines of longitudinal ribs, but rather from 

 revolving sculpture ; columella with two plaits, whitish. 



Length, 17 mill. 



Cape Sable. Florida (Calkins). 



C. ANTIQUATA, Hinds. PL 5, fig. 88. 



Broadly excavate.d below the suture, widely and deeply um- 

 bilicated, keeled and spinose at the shoulder and umbilicus; the 

 spines being the terminations of sharply plicate ribs ; otherwise 

 smooth ; columella rather obsoletely biplicate ; blush or yellowish 

 white. Length, *75 inch. 



New Guinea, 22 fms., coarse sand (Hinds). 



S. SCALARINA. Lam. PL 6, fig. 91. 



Umbilicated, distantly ribbed, spirally finely striate ; yellowish 

 white, more or less clouded with light chestnut, with frequently 

 a central white band. Length, 1-1-25 inches. 



Isle of France. 



Sowerby and Reeve have figured the next species for this. 



C. THOMASIANA, Crosse. PL 6, figs. 92-94. 



Scarcely umbilicated, turreted, whorls excavated at the suture, 

 border sharply spinosely keeled, obliquely, narrowly, distantly
