A series of specimens shows this species to be very variable in its 
sculpture, and there can be little doubt that the C. evanadus, Sowb. 
(ib. p. 291, C. IIL, f. 139), is one of these varieties, with which the 
specimens collected by the Expedition mostly correspond in form and 
colouring. In some small specimens the central areas are smooth, and 
the striz on the lateral areas are somewhat granular; but in very old 
specimens the central areas are deeply furrowed with longitudinal 
strie, which widely diverge at the sides. In all the varieties the strie 
of the lateral areas are coarse, irregular, and repeatedly divaricating. 
The tips are always roseate ; no specimens agree exactly with either 
of the descriptions, but the general features are so allied as to deter 
ine from giving it a new name.
