this species. C. Luzonicus, Sowb., not Hwass (fig. 16a), and C. 
comptus, Gould (PI. 27, fig. 9), are synonyms. 
Var. REGALITATUS, Sowb. PI. 20, fig. 17. 
Shell more completely covered with dark color, so as to 
obscure the articulated lines; but little of the lighter markings 
is visible beyond an interrupted central band. 
C. TxsTUDINARIUS (Mart.), Auct. Pl. 20, fig. 18. 
Whitish, more or less stained with blue or purple, and clouded 
with chocolate, irregularly white-banded in the middle; spire 
and base striate. Length, 2°5-3-5 inches. 
West Indies, Cape Verd Is., West Coast of Africa. 
Allied to C. purpurascens, but not so broadly shouldered, with 
higher spire. CC. aspersus, Sowb., and C. Portoricanus, Hwass, 
are synonyms. 
C. FULMEN, Reeve. PI. 20, fig. 19. 
Shell somewhat elongately ovate, smooth, slightly grooved 
towards the base; pale rose-purple, white round the middle; 
longitudinally marked with two or three very prominent, broad, 
waved, purple-brown streaks; spire obtusely convex, variegated 
with purple-brown, apex rose-tinted. Length, 2-3 inches. 
China, Japan, Philippines. 
Narrower, with higher spire, than the allied species. C. 
modestus, Sowb., is supposed by Sowerby (Thes. Conch., Index) 
to be a young shell of this species.

Shell turbinate, rather angulate at the shoulder; spire and 
base striate; pinkish or violaceous white, with broad, chestnut, 
longitudinal flames. Length, 1-75 inches. West Africa.

Shell inflated, rather thin, spire and lower portion of body- 
whorl striate; chestnut or olivaceous, with usually two bands of 
irregular white cloudings, and scattered white spots; aperture 
chocolate-color, faintly white-banded in the middle.
