12 CONUS. 



Reeve's original description and figure were made from a dead, 

 faded and depauperate shell (fig. 29). 



C. PROTEUS, 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. C. 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- 

 culits, Sowb., are also synonyms ; and C. armillatus, C. B. Ad., 

 is a young shell. 



Tar. BICOLOR, Sowb. PL 2, fig. 34. 



Shell shorter and wider at the spire than the usual form. 



West Africa. 

 Yar. PAPILIONACEUS, Hwass. PL 2, fig. 35. 



Spire generally more depressed than in the t} r pical 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. 



Yar. SIAMENSIS, Hwass. PL 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. FLAMMEUS, Lam. PL 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. 



Wn.tt Coast of Africa; Honduras (Dyson), 



This is the C. Lorenzianus of Chemnitz, and very probably 

 only a variety of C. Froteu*, Ilwass.
