Hab. Panama and Bay of Guayaquil ; six to eleven fathoms, in 

 sandy mud : Cuming. 



Closely allied to T. polita.

 etiam ventrali magis convexo. Long. 0'60 ; lat. 1*55 poll. 

 Hab. Red Sea? Mus. Cuming, Deshayes.

Tellina tulipa. Tel. testd T. Donacinse simillimd, sed subcequi- 

 laterali, et margine dorsali rosei coloris experte. Long. 0"50 ; 

 lat. 0-95 poll. 



Hab. ? Mus. Cuming, Walton. 



Extremely like T. Donacina, but almost equilateral, and devoid of 

 the short vertical ray at the beaks and the rosy dorsal edges which 

 are characteristic of that species.

 Hab. Isle of Ticao, six fathoms. 



Mr. Cuming's unique specimen of this curious shell possesses cha- 

 racters which cannot readily be confounded with any other species. 

 It is to Gargadia, however, that it is most allied.
