10 CONUS. 



Pattern of coloring very like C. marmoreus, but lighter; the 

 shell is immediately distinguished by the want of the coronal of 

 tubercles and its usually small size. Mr. Melville, of Prestwich, 

 m-ar Manchester, England, who possesses a remarkable collec- 

 tion of Cones, has sent me a colored drawing of a gigantic 

 specimen in his collection, 2'25 inches in length; he proposes to 

 call it var. eudoxus (PL 27, fig. 3). 



Section II. LITERATI. 

 Lithoconus (ex parte), Morch. 



C. LITERATUS, Linn. PL 2, figs. 17-19. 



Shell white, with usually two or three broad light yellow or 

 orange-brown bands, marked with revolving series of large and 

 small dark chocolate or nearly black, round, square or triangular 

 spots ; these spots are frequently elongated longitudinally, and 

 sometimes partially coalesce so as to form interrupted longi- 

 tudinal stripes ; base of shell often tinged with chocolate. 



Length, 3-5-5 inches. 



Zanzibar, Ceylon, Java, Singapore, New Caledonia, Viti Is. 



C. Gruneri, Reeve (fig. 18), from the island of Java, appears 

 to be a young shell without any distinguishable characters. 



- Var. MILLEPUNCTATUS, Lam. PL 2, fig. 19. 



Said to differ from C. literatus in the spots being smaller and 

 much more numerous, and in the absence of the yellow bands. 

 It is connected by intermediate stages with the typical literatus. 



C. OELATUS, A. Adams. PL 2, fig. 20. 



Shell small, with revolving grooves, which are longitudinally 

 striate ; spire minutely coronate, the apex acutely elevated ; 

 white, widely reticulated with orange. Length, 16 mill. 



China. 



I am not acquainted with this species. 



C. PLANAXIS, Deshayes. PL 2, fig. 21. 



Yellowish, encircled by narrow, more or less interrupted 

 chestnut lines, chocolate-tinged at the base. Length, 19 mill. 



Isle of Jiourbon. 



An unsatisfactory species, being evidently described from a 

 very young shell.
