 Hab. Panama, St. Elena. Mus. Cuming, Hanley. 

 The general outline, ovving to the abruptness of its slopas, closely 

 resembles that of excisa ; but in that species the sulci (or rather cos- 

 tellae) are elevated, the hinder dorsal area is excavated, and the lunule

 margin. 



Artemis subquadrata. Art. testd suborbiculari, subguadratd, 

 compressd, subpellucidd, valde in<Bquilaterali, intus extusque albidd, 

 concentrice substriatd ; margine ventrali postici arcuato, antice 

 convexo et sursilm acclivi ; dorsali antice convexo haudgiie declivi, 

 postice subrecto et declivi; extremitate posticd latissimd, anticd 

 angustd ; lunuld magnd, subobsoletd. Long. 1'62; lat. 1'75 poli.
