"This form much resembles in shape the typical E.Kellettii, 

 from which it differs in the absence uf the yeMow flecking and the 

 different surface sculpture. E. Kellettii is also a more globose 

 shell. The same stock, doubtless, was the origin of both species, 

 as well as several others/'— Dull, 101-105, t 8, f 19.

 of largest specimen obtained 27, minor 22, alt. 19 mm. This is 

 from the type locality of Stearnsiana, which was much more abun- 

 dant and differing not at all from San Diego specimens. Orcutt
