 Marta range at about 2,500 ft. elevation. (H. H. Smith.) 



The spotted pattern of the spire recalls some forms of D. trigono- 

 stomus, but in the structure of the aperture and columella it is near 

 D. castus.

U A single specimen only has been received of this pretty shell. 

 The combination of color and markings render it an object of much 

 beauty. The cancellation produced by the chocolate bands crossed

 ticed appearance, which is sharply defined within the interior; under 

 the lens the nepionic whorls show the usual thimble-like sculpture of 

 Drymasus." (Da Costa.)
