 attenuatd; ab utroque, superficie nitidissimd, ligamento infosso, 

 margineque ventrali convexiore et utrinque subcequaliter declivi; 

 sulcis in utrdque valvuld postice obsoletis ; dentibus ut in T. pu-

 roseo-purpurascente, concentrice sulcatd; sulcis remotis, alterd in

 Hab. Real Llejos, Central America ; in coarse sandy mud, seven 



fathoms. 



This species forms one of that group of which punicea is the 



type. Though closely allied to that species, its transparency, the 



more distant sulci, and its deep purplish-red colouring suffice to 



distinguish it.
