208 1'ISSUUEU.ID.E. 



This species, figured from a specimen in Mr. Cuming's collection, 

 is of quite a different form to C.fastigiata, and seems to approach 

 more nearly to C. noacldna in specific characters. 



4. citcullata (f. 3, 4, 5), Gould. — Solida, cinerea, perin- 

 sequilateralis, costis ad 40 ncutis compressis majoribus et mino- 

 ribus alternantibus radiata, et striis concentricis confertis muri- 

 eata ; apice elevato, acuto, ad unco, prorsum spectante ; fissura 

 laneeolata; apertura ovata, margine sulcis insequalibus alternan- 

 tibus ereuulato ; facie interna porcellana ; fornice tenui, simplici, 

 arcuato. 



5. nobilis, (f. 6-9), A. Adams. — Elato-conica, vertice acumi- 

 nata, prorsum inclinato, acuto; costis longitudinalibus, validis, 

 sequidistantibus ; interstitiis striis concentricis instructs; fissura 

 angusta, laneeolata, margine valde crenato. Obs. Resembling 

 C. cucullata of Gould, but with the ribs stronger, wider apart, 

 and equal ; the apex, moreover, is considerably more elevated and 

 acute. 



G. cognita (f. 13), Gould. — Conica, alba, radiatim costulata ; 

 apice incurvato ; apertura rotundato-ovali. Obs. Similar to Ce- 

 moria conica, D'Orb., but less elevated and the ribs more regular 

 [Gould). 



7. Palklandica (f. 14), A.Adams. — Albida, conica, apice incur- 

 vato, radiatim costata; costis longitudinalibus, validis, subdistan- 

 tibus, sequalibus, striis concentricis confertis corrugatis; fissura 

 angusta, laneeolata ; apertura ovata, margine crenato, fornice costa 

 transversali. Obs. In this species the ribs are very distinct, and 

 the concentric raised lines are acuminate where they cross the 

 ribs. 



8. fastigiata (f. 1 5, 16), A. Adams. — Albida, elevato-conica, 

 nitida, vertice acuminata involuto, costellis longitudinalibus sequa- 

 libus sequidistantibus, interstitiis planis lineis increment] concen- 

 tricis; fissura laneeolata; apertura ovaiis, margine crenulato, for- 

 nice costa valde arcuata, transversali, simplici. 



Genus CRANOPSIS, A. Adams. 



Plate X. 



Gen. Char. Testa conica, capuliformis, exliis cancellata, apice 

 rccurvo integro; fissura, in medio posita inter apicemet marginem 

 anticani, fornice interno arcuato.
