Turbo siriits. Testa parva, imperforata, pyramidata, dilute 

 beryllina, leviter corrugata; spira anfr. 4 conicis, infra oblique 

 plicatis, ad peripheriam acutis et spinis compressis ad IS armatis : 

 basis planulata, stellaris, liris concentricis muricatis ad 5 insculp- 

 tis ; regione columellari arcuata, lsevigata ; labro perobliquo. 

 Diam. £, axis T 3 g- poll. Hab. New Holland. 



The multitude and regularity of the triangular projections of 

 the periphery, when viewed from below, give the base a beauti- 

 ful star-like form, much like T. stellaris. 



Turbo laciniatus. Testa rudis, depresso-conica, cinerea 

 roseo-tincta : spira anfr. 4, irregulariter plicatis, plicis ad peri- 

 pheriam acutissimis, dilatatis et in spinis elongatis compressis 

 excurrentibus : basis convexiuscula, liris muricatis concentricis 

 10 - 12 insculpta : apertura circularis ; columella la?vi, arcuata, 

 rosea ; labio perobliquo : faux margaritacea. Lat. f , alt. •§ poll. 

 Hab. Manilla. 



Closely allied to T. rhodostomus, Lk., but wants the double 

 series of spines at the periphery. 



Trochus pruninus. Testa solidula, elevata, ovalo-conica, 

 lsevis, nitida, prunina, lineis capillaceis numerosis cincta : spira 

 anfr. 7 convexiusculis, ultimo subangulato ; sutura profunda : 

 apertura subcircularis ; columella rotundata, alba, antice roseo- 

 tincta, subsinuosa : interior margaritacea, vivide iridescens. Alt. 

 ■§■, lat. -Jjs poll. Hab. Auckland Island. 



This peculiarly colored species has the form, thickness, and 

 appearance of the delicately lineated specimens of Lillorina 

 angulifera. 



Trochus texturatus. Testa conica, imperforata, solida, cin- 

 erea viridi vel roseo-tincta, liris volventibus roseo-maculatis et 

 laminis incrementi tenuibus clathrata : spira anfr. 7, vix convexis, 

 ultimo sub-angulato : apertura rotundata, antice evoluta ; col- 

 umella rotundata, labro declivi, acuto : interior margaritacea, 

 iridescens. Alt. 1, lat. fo poll. Hab. New Zealand. 



This may be well compared with the coarse, solid, sulcated 

 variety of Litiorina angulifera. 



Trochus ligatus. Testa solida, ovato-conica, imperforata^ 

 costulis rotundatis flavescentibus ubique cincta, intervallis incar-
