1. Corbicula Ijarnaiiflieri, nov. sp. 



T. ovato-transversa, iuaequilaterali, convexius- 

 cula, antice paulo longiore, utraque extremitate 

 rotundata ; nmbonibus parvis, turgidulis, integris ; 

 lunula ovato-lanceolata, pallida; sulcis distantibus ; 

 epidermide flavescente-viridi, vestita ad umbones 

 atroviolascente radiata ; iutus violacca ; cardine 

 ingequaliter tridentato ; dentibus lateralibus an- 

 gustis, tenue striatis. 



Long. 13; lat. 11 ; diam. 7 mill,

Eab.—^'vAm. (My Cabinet.) 



This small species is somewhat convex, slightly inequilateral, 

 the lunula is distinct, the beaks though small are a little raised 

 and curve inwardly, the striae are regular and far apart, the 

 epidermis is glossy and of a yellowish-green coloi', with distinct 

 markingfs of dark violet on the beaks. 



Somewhat like the C. tumida from Borneo; it is, however, 

 smaller, less heavy, more inequilateral, less convex, the striae 

 are not so far^ apart, and the epidermis is of a lighter and 

 brighter color. 



The C. Larnaiidieri, so called in honor of the Abbe Lar- 

 naudier, was discovered in Siam by that gentleman, who 

 formed part of the embassy sent to that country a few years 

 since by the French Government ; he only collected the two 

 specimens now in my cabinet, which I obtained from him 

 through Mr. Bernard! of Paris.
