 angulatus, supra angulum leviter concavus, liris spiralibus 2 — 3 

 instructus, basim versus subobsolete sulcatus ; apertura oblonga,

This species, collected at the above locality by the late Mr. G. H. 

 Booley, differs from C. pila to which it has some general resemblance 

 in the following particulars. The body whorl, instead of being 

 regularly grooved as in C. jnla, is almost smooth but longitudinally 

 striated ; it has an obtuse angle at the top, between which and the 

 suture it is slightly concave, with two or three distinct spiral ridges. 

 The examination of a considerable number of specimens of both 

 species has confirmed my opinion that they are distinct.
