teriorly quite obsolete in one of the valves ; emargination almost 

 obsolete.

Easily distinguished from Striata, by its closer and more delicate 

 sulci, its less prominent beaks, and the absence of all radiation. It 

 is also thicker and more opaque, and remarkable for the slight in- 

 dentation which terminates the rather flattened space adjacent to 

 the front dorsal edge, a character which is not possessed by any of 

 the allied species.

T. testa ovali-subtrigona, solidiuscula, subpcllucida, convexius- 

 cula, nitida, aut albido-rosea radio roseo utrinque ornata, aut al- 

 bida, radio flavescente ; concentrice sulcata, sulcis remotis, altera 

 in valvula postice evanescentibus ; margine ventrah paululum con- 

 vexiusculo ; dorsab utrinque declivi, antice convexiusculo, postice 

 subrecto; latere antico longiore, postico truncato-cuneiformi ; 

 extremitate antica simplici, rotundata ; flexura, costaque umbonali 

 inconspicuis ; natibus acutis, palbdis ; ligamento prominente ; den- 

 tibus ut in Punicea. 



Subangularly oval, moderately sobd and convex, either pale 

 pink with a roseate ray down the obsolete umbonal ridge (preceded 

 by a paler streak) and a short roseate ray in front of the acute and 

 prominent beaks, or white with the rays yellowish ; surface grooved 

 by subimbricated distant sidci, which disappear on one of the 

 valves at the truncate wedge-shaped hinder extremity; ventral 

 edge but slightly convex ; anterior side the longer, its extremity 

 simply rounded and never indented, its dorsal edge but moderately 

 sloping and sbghtly convex ; hinder dorsal edge sloping and nearly 

 straight ; flexure nearly obsolete ; teeth as in Punicea.

The rays are never absent, and the anterior side is always the 

 longer. Mr. Sowerby informs me, that this is the Tellinides rosacea 

 of King (Zool. Journ. vol. 5.), which is too briefly defined for re- 

 cognition.
