CONUS. 37 



C. CLERTI, Reeve. PL 10, fig. 94. 



Shell finely ridged throughout ; white, variegated with choco- 

 late longitudinal flammules and streaks. Length, 1'25 inches. 



Brazil, Venezuela, West Indies, 



C. MINUTUS, Reeve. PI. 10, fig. 95 a. 



Shell flesh-color, with two approximate, central brown bands. 



Length, 9 mill. 



Island of St. Vincent, West Indies. 



This is a very young shell, and should not have been described 

 as a distinct species, as its adult state is very probably known 

 under another name. 



C. EMARGINATUS, Reeve. PL 10, figs. 95, 96. 



Shell with conically elevated, channeled spire; body-whorl 

 grooved below, its sides concave ; white, longitudinally streaked 

 and flamed with chocolate. Length, 45 mill. 



Venezuela to Brazil. 



Very probably equals C. Clerii, from which it differs mainly 

 in the want of striae on the upper portion of the body-whorl, 

 and its somewhat more concave sides. C. lentiginosus , Reeve 

 (fig. 96), is considered a variety by Dr. Weinkauff. 



C. VILLEPINI, Bernard! and Fischer. PL 10, fig. 97. 



Shell smooth, with sharply angled shoulder, grooved towards 

 the base, and striate spire ; yellowish white, with chocolate 

 maculations forming three obscure bands. Length, 30 mill. 



Marie Galante, West Indies. 



Is possibly a variety of C. eniarginatus. 



C. REGULARIS, Sowb. PL 11, figs. 98-2. 



Shell white or yellowish white, with chestnut-chocolate macu- 

 lations and spots, variously arranged in revolving series ; some- 

 times the ground-color of the shell is chestnut, with dark 

 chocolate markings and chocolate aperture ; spire somewhat 

 concavely elevated, with acute apex ; epidermis thin, smooth, 

 translucent. Length, l'5-2'5 inches. 



Panama to Mazatlan, Guaymas. 



One of the most characteristic species of the West Coast of 

 Mexico. Its synonyms include C. dispar, Sowb. (fig. 2), C. 

 incur viiSj Kiener (fig. 100), and C. angulatus, A. Ad. (fig. 1).
