12 CONUS. 
Reeve’s original description and figure were made from a dead, 
faded and depauperate shell (fig. 29). 
C. Proreus, Hwass. Pl. 2, figs. 30-35; Pl. 3, fig. 36. 
Shell white, with revolving series of spots and irregular or 
cloud-like markings of orange, chestnut or chocolate, often form- 
ing interrupted bands; base grooved, spire with a single broad 
sulcus. Length, 1°5-2°5 inches. 
¢ West Indies, Florida. 
Dr. Weinkauff has distinguished C. leoninus, Chemn., not 
Hwass, said to come from the East Indies, but it does not 
appear to me to be different; C. leoninus of Hwass (fig. 31) is 
certainly the same. OC. spurius, Gmelin, of authors (fig. 32) 
may also be placed here confidently, but the original description 
must remain a doubtful identification. C. ochraceus, Lam. (fig. 
33 ,if correctly identified by Reeve and Sowerby, and C. brevi- 
culus, Sowb., are also synonyms; and C. armillatus, C. B. Ad., 
is a young shell. 
Var. BICOLOR, Sowb. PI. 2, fig. 34. 
Shell shorter and wider at the spire than the usual form. 
West Africa. 
Var. PAPILIONACEUS, Hwass. PI. 2, fig. 35. 
Spire generally more depressed than in the typical form, the 
revolving rows of spots of smaller size, closer and more numerous. 
Length, 2—2°5 inches. 
Senegal; Canaries; St. Thomas, West Indies (Swift). 
Merges into the type by insensible gradations. 
Var. SIAMENSIS, Hwass. PI. 3, fig. 36. 
Distinguished from var. papilionaceus by having more numer- 
ous narrow articulated fillets. The locality indicated by the 
name is exceedingly doubtful. 
C. FLAMMEvS, Lam. PI. 3, fig. 37. 
Yellowish white, flamed and spotted with chestnut, the flames 
usually longitudinally disposed, forming revolving bands, the 
spots in revolving series. Length, 2-2°75 inches. 
West Coast of Africa; Honduras (Dyson). 
This is the C. Lorenzianus of Chemnitz, and very probably 
only a variety of C. Proteus, Hwass.
