said to have fine concentric striae anteriorly, that become obsolete 

 at the middle. 



Tellina compta. T. parva, transversa, inequilateralis, alba 

 vel rubescens, quater roseo-radiata ; umbonibus ad trientem pos- 

 ticum sitis ; latere antico semi-elliptico ; latere siphonali trian- 

 gulari apice truncato, vix insculpto, plicate ; marginibus (scilicet 

 dorsali et ventrali,) fere parallelis ; disco striis concentricis et 

 striis obliquis arato ; dentibus lateralibus nullis ; intus ex albo fla- 

 vescens, radiatim striata. Long, f ; alt. ^ ; lat. ^ poll. Hah. 



Almost precisely like T. decora, which has a well marked 

 lateral tooth, and comes from the West Indies. T. rhomhoides, 

 Quoy, varies chiefly in the more partial development of oblique 

 stricc. The coloring is less brilliant, and the striae more delicate, 

 more oblique, and cover a greater proportion of the valve than 

 T. lauta. 



Tellina exculta. T. transversa, solida, trigono-elliptica, 

 tumida, nitida, albida, rosaceo vix radiata, concentrice liris tenu- 

 ibus et radiatim striis tenuissimis insculpta ; liris in valva dextra 

 postice lamellosis et interruptis, squamas simulantibus ; in valvse 

 sinistrae disco valde obliquis ; umbonibus postmedianis ; latere 

 anticali semi-elliptica ; latere posticali subtriangulari, ad apicem 

 valde truncato; flexura insigni, baud lamellosa : cavositas flava ; 

 dentibus valvse dextra3 conspicuis. Long. 2 ; alt. 1 ; lat. J-^ poll.

Looks like a variety of T. rastellum, Hanley, (T. Philippii, 

 Anton,) but is proportionally shorter, the beaks are farther back, 

 and the disc is more tumid anteriorly. The laminae of the right 

 valve are everywhere more delicate, and nearly absent on the 

 anterior half; the scales are confined to the valley in front of the 

 fold. The oblique grooving on the left valve is very decided. 



Tellina concentrica. T. transversa, ovato-trigona, tenuis, 

 convexiuscula, albida, baud nitida, ubique concentrice lamellosa, 

 et radiatim inter lamellas subtilissime striata ; lamellis aequalibus, 

 acutis, confertis, reflexis; umbonibus vix post-medianis : pars 

 antica semi-elliptica ; margine dorsali vix declivi : pars postica 

 sub-triangularis ; margine dorsali valde declivi, sub-arcuato, 

 valde excavate, ad apicem truncato ; flexura conspicua, baud
