elongated across the base, the inner ones small and confined 

 to the aperture. Length, 1*4-1 '85 inches. 



Gape of Good Hope. 



This shell in a perfect condition is the C. castanea, Higgins 

 (PL 17, fig. G9). The specimens usually fourid in collections, 

 however, are of a yellowish color and are without any dorsal 

 ornamention except around the spire, where it is sometimes 

 brownish. 



** Margins more or less pitted, dorsal spots usually ocellated. 

 C. CRIBRARIA, Linn. PL 17, figs. 71, 72. 



Yellowish brown, dorsal spots round, white, sides and base 

 white, teeth numerous, those on the inner lip confined to the 

 interior of the aperture. Length, -7-l'l inches.

Mr. Rossiter, of New South Wales, reported having obtained 

 specimens of a blackish-brown color, showing but few of the white 

 spots, and 1*5 inches long. 



Although this species may be said to possess no marginal

C.fallax, E. A. Smith, is an unfigured variety, credited to 

 West Australia. It differs from the normal shell in being 

 larger, more pyriform, white spots smaller and less clearly 

 defined ; they appear to blend into the fawn-color of the dorsum, 

 which is paler than in C. cribraria. 



C. CRIBELLUM, Gask. PL 17, figs. 66, 67. 



Smaller and more cylindrical than C. cribraria, extremities 

 more obtuse, aperture wider, margins spotted. Length, *7 inch. 



Mauritius. 

 C. COXENI, Cox. PL 17, figs. 64, 65. 



Differs from C. cribraria, in the dorsal ornamentation, which 

 is in irregular elongated dark chestnut markings, teeth coarser 

 and prominently produced a little more than half-way across the 

 base. Length, *92 inch.
