Original description : — Testa transverse ovato-rhomboidea, in- 

 a;quilaterali, crassiuscula, tumida, antice rotundata, postice alata, 

 recta, turn valde declivi, demum subangulata, margine ventrali 

 convexo ; disco lajvigato, polito, vix striatulo, sub epidermide 

 pulchre viridi tenuissima obscure radiata albo, margine lutescente ; 

 umbonibus prominentibus, apicibiis approximatis, subdecorticatis, 

 margaritaceis, breviter et minute radiato-sulcatis ; lunula angusta, 

 elongata, transverse rugata ; ligamento subelongato ; cai'ina um- 

 bonali prominente obtusiuscula, areola versus apicem depressi- 

 uscula, viridi obscure radiata ; dentibus cardinalibus duplicibus, 

 subangustis, rugosis, lateralibus curvatis elougatiusculis, valvae 

 dextrie simplicibus, sinistrae duplicibus, uonnunquam subtri-

Long. 31, lat. 42, diam. 20 mm. 



The above description is amplified by the following note : — 



"Remarkable for the smoothness of the beautiful green 

 epidermis, which is very thin, and, when rubbed off, exhibits a 

 plain white colour, not nacreous, underneath. The anterior 

 cicatrices are confluent, the posterior nearly distinct, the apical 

 ones situated under the cardinal teeth. Cavity of beaks very 

 deep ; a few ruga? cross the stria) on the posterior slope. In 

 general characters it approaches most nearly to the Jellingyhy 

 variety {deltce) of U. [P. (P.)] favidens, which has a more tumid 

 ovate form, a regular, sulcate, olivaceous surface, longer and dis- 

 tinctly angulate-flexuous umbonal furrows, and a broad lunule."

 of the Indian Museum bearing the Burmese localities, Bhamo and
