Species 36. (Mus. Cuming.) 



Arte Ji IS sericea. Art. tesid transverse ovatd, latiore 

 qmm alia, coiiceidrice tenuissime striata, area liga- 

 nienti simpUci, subplanatd, lunula cordatd, subampld ; 

 flavicnnte-alhd, unbones versus cameo tmcld.

 than high, eonceutrically very finely striated, area of 

 the ligament simple, a little flattened, lunule heart-

Ilab. Japan ; Dr. Siebold. 



The minnte and delicate character of the concentric 

 striiE give the shell a sOken aspect. 



Species 44. (Mus. Taylor.) 



Artemis Orbignyi. Art. testd orbiculari, solidd, plano- 

 conve.m, concentrice striaid, striis lennibus, elevaii- 

 usculis, regularibus, ad latera paucioribus, area liga- 

 menti laHceolato-e.vcavatd, lunula cordatd, subimpressd ; 

 albd, umbones versus livido-fuscescenlibus. 



D'Orbigny's Artemis. Shell orbicular, solid, flatly 

 convex, concentrically striated, strise fine, ratjier 

 elevated, regidav, fewer in number at the sides, area

 pi. G.f.3. 



llab. Guinea ; Tarns. 



A shell of rather solid growth, in which the striaj are 



rather distant and have the appearance of fine cords. I 



doubt if Philippi's A. Uvida is anything more than a 



variety of this species. 



Species 45. (Mus. Cuming.) 



Artemis Lucinoides. Art. testd sahquadrato-orhicidari, 

 medio tmnidd, postice subcontractd, concentrice subti- 

 lissime et creberrirne striata, striis ad latera vix pau-

 cordatd, inipressd; sordide albd. 



The Lucina-like Artemis. Shell somewhat squarely 

 orbicular, swollen in the middle, sliglitly contracted

 cante, umhonibus ad apices roseis.

Hab. — ? 



One of the chief peculiarities of this species consists in 

 the strife ranging oft" on the posterior side in pairs.

 vexd, compressd, concentrice subtilissime et creberrirne
