C. CAURICA, Linn. PI. 5, figs. 88, 89, 90. 



Whitish, mottled with minute yellowish-brown specks, sides 

 whitish to pale orange, ornamented here and there with dark 

 conspicuous spots, base orange tinged with gray, teeth very 

 strong, whitish, extending parti-ally over the base on each side. 



Length, '9-1*8 inches. 



Indian and Pacific Oceans. 



A most abundant species, varying from long and rounded 

 forms, with thin sides, to those short and depressed, with 

 thickened sides. The dorsal surface is frequently ornLrbonted 

 with a reddish-brown spot. A blackish-brown variety from 

 New Caledonia is the 0. obscura, Kossiter. 



C. ORUENTA, Gmel. PL 6, fig. 97. 



Differs from the preceding in the delicate dorsal coloring, 

 which is interrupted by more or less distinct white spots of 

 unequal size ; the side spots are purple and the interstices of the 

 teeth bright red ; the teeth on the columella are usually confined^ 

 more to the margin of the aperture. ' Length, -8-1 '8 inches. 



Indian Ocean, N. S. Wales. 



C. STOLTDA, Linn. PL 5, figs. 91, 92, 85 ; PL 6, fig. 7. 



Bluish, painted with minute chestnut dots, with a large brown 

 central square spot connected with half-square spots of the 

 same color at each corner, base paler blue, teeth and extremities 

 dark orange, the teeth extend somewhat over the base, mar- 

 ginal dots very small. Length, 1*11*5 inches. 



Ceylon, Borneo, Sandwich Is. (?), N. Caledonia. 



C. brevidentata, Sowb. (fig. 85), is a variety in which the 

 teeth are short, rounded and fewer in number ; they are con- 

 fined to the margin of the aperture, and are not tinted ; the 

 dorsal appearance is like incompletely colored specimens of 

 stolida. 



C. Crossei, Marie (PL 6, fig. 7), is another variety in which 

 the extremities are greatly produced and curve upward, the 

 central spot of the typical stolida is here extended into a band 

 and the whole shell has the distorted appearance so peculiar to 

 many of the species from New Caledonia. The teeih are large, 

 white and extend over the base of the shell.
