T. testa ovato-oblonga, solidiuscula, subimpolitaj compressa, 

 aequilaterali, albida, concentrice et confertissirne striata ; margine 

 ventrali vaide arcuato ; dorsali utrinque subdeclivi, antice subrecto, 

 postice incurvato et lamellis subdentato ; extremitate antica rotun- 

 data ; latere postico acuminato, subrostrato ; costa umbonali con- 

 spicua ; flexura satis distincta ; natibus acutis ; Hgamento infosso ; 

 disco interno aurantio ; dentibus lateralibus, subremotis, subsequi- 

 distantibus. 



Ovate-oblong, tolerably strong, rather dull, whitish, (with often 

 a tinge of orange in the front part of the umbones, and the internal 

 disc always of that colour,) equilateral, compressed, with crowded 

 concentric strise ; ventral edge much arcuated ; dorsal moderately 

 sloping on either side of the acute beaks, nearly straight in front, 

 incurved behind and somewhat toothed by the lameUse, (wliich in 

 some specimens commence before the conspicuous fold) ; ligament 

 sunken ; lateral teeth distinct, and nearly equally remote.

26. Tellina PHAEAONis (pl.lxiii. f.215.) iZa;?%, Zool.Proc. 

 1844. 



T. testa T. Vulsella simillima, sed sohda Uneisque elevatis con- 

 centrice striata, umbonibus aurantio-roseis ; flexura sinuata. 



Extremely like T. Vtdsella, but solid, and rough with concentric 

 elevated striae ; fold sinuated. 



In the only specimen I have ever seen, one of the valves is of a 

 dehcate pink, the other white tinged with the same hue, the beaks 

 of a very rosy orange and the ventral flexure so deep as to form a 

 sinus ; the lower margin is not so convex in front as in Rostrata ; 

 the front lateral tooth is distinctly crenated, but tliis is probably 

 accidental.
