26 COCHLOSTYLA-HYPSELOSTYLA. 



Var. BOHOLEXSIS Brocl. PI. 12, figs. 6, 7, 8, 9, 10. 



Shell lengthened, but variable in degree of elongation ; subcar- 

 inated or almost rounded at the periphery; whorls 6* to 7]. 

 Ground color yellowish, becoming tawny below, paler above, the 

 earlier two or three whorls brown, covered with a cream-white 

 hydrophanous cuticle, which is cut by zigzag stripes (figs. 8, 10) or 

 by spots (fig. 9) of the ground color. Lip dark brown. 



Alt. 42, diam. 22 ; aperture, alt. 22 mill. (fig. 6). 



Alt. 49, diam. 201 ; aperture, alt. 22 mill. (fig. 10).

There are often dark bands upon the light ground color, at suture, 

 periphery and columella, as shown in figs. 7, 9 ; but these are as 

 frequently lacking. Figs. 6, 7, 9, 10, drawn from specimens now 

 before me, show that the pattern of cuticle is excessively variable. 

 Fig. 8 is also a common pattern. 



This form is so intimately related to C. camelopardalis that I can 

 only admit it to the rank of a local variety, characterized by the 

 color pattern only.
