198. f. 1933. (Solen Diphos Chinensis). 



In the recent state, this shell is covered with a green- 

 ish epidermis; but, in cabinets, it is generally seen 

 without its native covering, and is of a violet colour, 

 with numerous rays diverging from the apex to the 

 margin; it gapes at both ends, is rounded behind, but 

 projecting into a beak before; the inside is wholly 

 violet, but on the outside, the violet is mixed with white. 

 Two white rays are figured by Chemnitz, crossing the 

 shell obliquely from the apex ; but these rays were not 

 remarkable in our specimen. The hinge has two teeth 

 in one valve, and one in the other. 



Inhabits the Indian Ocean. 



The variety described by Chemnitz, under the name 

 of Solen Diphos Chinensis, is a rounder shell, with two 

 very conspicuous white rays.
