78 CONUS. 



marginatus, Sowb. (fig. 10), and C. Lizardensis, Crosse (fig. 11), 

 are referred as synonyms to this species by Dr. Weinkauff ; they 

 are both young shells. 



C. VERRUCOSUS, Hwass. PL 24, figs. 12-18. 



Spire raised, smooth, slightly gradate, sometimes obsoletely 

 tuberculate ; body-whorl distantly, narrowly sulcate ; spaces 

 between the sulci plane, sometimes smooth, usually tuberculated ; 

 yellowish white, irregularly clouded with orange or chestnut. 



Length, '75-1-2 inches. 



W. Coast of Africa, West Indies. 



The smoother form of this species is usualty known under the 

 name of acutangulus, Hwass which is a Philippine Islands shell, 

 differing in its smaller size, want of tubercles and punctured sul- 

 cations. C. echinulatus, Kiener (fig. 13), C. nodiferus, Kiener 

 (fig. 15), C. sticticus, A. Ad. (fig. 14), C. Mindanus, Hwass (fig. 

 16), C. cretaceus, Kiener (fig. 17), C. anaglypticus, Crosse (fig. 

 18), and possibly C. elventinus, Duclos, are synonyms. 



C. CORRUGATUS, Sowb. PI. 24, fig. 19. 



Shell closely sulcate, the interstices raised, rounded and more 

 or less granular ; light chestnut, spotted with dark chestnut, with 

 a median lighter band. Length, *75 inch. 



China (specimen from Sowerby), 



A more slender and much more finely sculptured shell than 

 C. verrucosus, with the edges of the spire-whorls neatly spotted 

 with brown. 



C. PAPALIS, Weinkauff. PI. 24, fig. 20. 



Shell fusiformly turbinated, swollen at the shoulder, encircled 

 throughout with fine, equidistant ridges ; spire proportionally 

 large, elevated, strongly coronated, white ; body-whorl olive-ash, 

 marked below by small oblong-square white flakes. 



Length, -5 inch. 



Philippines. 



Undoubtedly a very young shell. It was described by Reeve 

 under the name of C. coronatus, preoccupied by Dillwyn for 

 another species. Is it a young C. pontificalis ?
