CONUS. Ve 
ash or chocolate cream-color, generally with an obscure light 
central band, sometimes with more or less obscure chestnut 
revolving lines, but generally these are absent; spire often 
radiately streaked with chestnut. 
This ‘variety is almost intermediate between the typical C. 
Jigulinus and C. glaucus, Hwass.

Shell small, slightly turbinated, brown, encircled with unevenly 
placed, thick, dark red-brown lines, aperture narrow, spire some- 
what rounded. Length, °63 inch. Smaller and with thicker and 
more irregular color-lines than the type; aperture narrower. 
C. queRcinus, Hwass. PI. 4, fig. 59. 
Shell lemon-yellow, with numerous fine, rather close, chestnut 
revolving lines; spire rather elevated, with concave outline, the

Red Sea, HE. Africa, Mauritius, Ceylon, Philippines, 
Viti Islands, Sandwich Islands. 
The revolving lines are much finer and closer than in the pre- 
ceding species of this group; the form of the spire is also 
different. In old specimens the revolving lines become 
obsolete; the shell in this state has received the name of C. 
ponderosus, Beck. 
C. pygirormMis, Reeve. Pl. 4, figs. 60, 61. 
Shell light flesh-color, the spire gently acuminate, the earlier 
whorls tuberculated, body-whorl pyriform, the outline concave
