CONUS. 45 



C. ^GROTUS, Reeve. PL 13, fig. 53. 



Shell oblong, turbinated, rather thick, somewhat rudely^ 

 twisted at the base, transversely obsoletely striated in a slightly 

 waved manner, irregularly longitudinally marked with lines of 

 growth ; spire flatly depressed, minutely obsoletely carinated 

 towards the apex ; cream-color, marked with rows of very 

 minute pale brown dots, leaving a white band in the centre ; 

 base dark livid violet. Length, 2 inches. 



Philippines. 

 C. LIVIDUS, Hwass. PL 13, figs. 54-57. ' 



Spire coronated, depressed conical, lower half of body-whorl 

 distantly striated, and the striae sparsely granulous ; light 

 yellowish or olivaceous to orange-brown, tubercles of the spire 

 and a band below the shoulder, as well as a central band on the 

 body-whorl, white, base and interior violaceous ; epidermis 

 somewhat tufted in distant revolving series. Length, 1*5-2 inches. 

 Red Sea to Polynesia, E. Africa, Mauritius. 



Differs from C.Jlavidus in having coronated whorls, a char- 

 acter which I fear is not specific. C. citrinus, Gmel. (fig. 55', 

 as usually, but perhaps incorrectly, identified, belongs here ; 

 Quoy, who describes the animal as bright red, calls it C. 

 sanguinolentus. 



Yar. SUGILLATUS, Reeve. PL 13, fig. 56. 



Tubercles oblique ; spire-whorls flatly channeled, more or less 

 stained brown ; the white bands of the body-whorl more dis- 

 tinct, the brown surface more or less resolved into very close, 

 faintly brown-spotted lines. 



Yar. CREPUSCULUM, Reeve. PL 13, fig. 57. 



Pale yellow, without white bands, of much lighter growth than 

 C. lividits, spire obsoletely finely beaded, aperture white. An 

 obscure form. Length, 28 mill. 



C. OBLITUS, Reeve. PL 13, fig. 58.' 



Shell narrow, with convexly depressed, tuberculated spire, 

 body-whorl striate below ; yellowish olivaceous, indistinctly white- 

 banded in the middle, tubercles, and a band below the shoulder 

 also white, base and aperture violaceous. 



Length, '9-1-25 inches.
