The prickly Xassa. Shell ovate, whitish ; whorls 

 rather flat, slantingly angled round the upper part, 

 longitudinally thinly plaited, plaits laterally appressed 

 and prickly nodose ; aperture small, with a small cal- 

 losity, lip thickened, varicose. 



A. Adams, Pro. Zool. See. March 18.51. 



JLi/i. Isle of Mindoro, Philippines (in sandy mud at three 

 fathoms) ; Cnraing. 

 The thin longitudinal plaits are peculiarly appressed on 



one side, and fall in jjrickly festoons.

The gemmed Nassa. Shell ovately conical, whitish or 

 ash-coloured, stained and banded with browii ; spire 

 sharp ; whorls longitudinally plaited, plaits nodulously 

 granulated, decussated by transverse grooves ; colu- 

 mella with a white expanded callosity, lip simple, in- 

 terior ridged. 



A. Adams, Pro. Zool. Soc. March 1851. 



Ifnh. Island of Burias, Philippines (in coarse sand at six 

 fathoms) ; Cuming. 

 The surface of this species is closely largely grannlated 



ihrousrhout. 



Species 133. (JIus. Cuming.) 

 Nassa c.elata. Nass. testd ovatd, acuminutd, albidd, 

 riifescentii fasciatd ; spird acuta, suturd siibcanalicii-

 The carved Nassa. Shell ovate, acnminated, whitish, 

 banded with pale red; spiresharp, sutwe slightly chan- 

 nelled ; whorls flatly convex, longitudinally densely 

 tine-ribbed, interstices neatly cancellated with trans- 

 verse ridges, riblets elongately granuled at the su- 

 tures ; columella short-laminated, lip varicose, inte- 

 rior ridged. 

 A. Adams, Pro. Zool. Soc. ^farch 1851. 



Hob. Island of ilindanao, Philippines (in sandy mud at 

 twenty-five fathoms) ; Cuming. 

 A solid closely cancellated species, in which the longitu- 

 dinal riblets have the form of elongated grannies next the 

 sutures. 



Fig. 134. (Mus. Cuming.) 

 A variety of N. variabilis of the preceding Plate, of more 

 transparent texture, less strongly plaited, with only the 

 faintest indication of a central band. 



Species 135. (Mus. Cuming.) 

 Nassa obtusata. Nass. testd subglohoso-conicd, alba, 

 rafo vittatim macidatd, longitudinaliter costatd, costis 

 distantibus, superne obtuse (icberculatis, interstitiis liris 

 transversis crebri-cancellatis ; uperturd parviusculd, 

 fauce liratd, cohmielld callosd, lahro iiicrassato, vari- 

 coso. 

 The blunted Nassa. Shell somewhat globosely conical, 

 white, filleted with spots of red, longitudinally ribbed, 

 ribs distant, tubercled at the upper part, interstices 

 closely cancellated with transverse ridges ; aperture 

 rather small, interior ridged, columella callous, lip 

 thickened, varicose. 

 A. Adams, Pro. Zool. Soc. March 1851. 

 Hab. Island of Ticao, Philippines (in coral sand at seven 

 fathoms) ; Cuming. 

 Chiefly distinguished by the obtuse widely separated 

 character of the ribs, and the fine-ridged sculpture of the 

 interstices. 



Species 136. (Mus. Cuming.) 



Nassa multicostata. Nass. testd ovatd, acuminata, 

 albd, interdum rufescente varieyatd, lonyitudinaliter 

 tenuicostatd, costis nunierosis, coiifertis ; columelld 

 callosd, lahro simplici, iufus obsolete denticulato. 



The many-ribbed Nassa. Shell ovate, acuminated, 

 white, sometimes variegated with pale red, longitudi- 

 >»ally finely ribbed, ribs numerous, close-set ; colu- 

 mella callous, lip simple, obsoletely denticulated 

 within. 



A. Adams, Pro. Zool. Soc. March 1851. 



Hah. Island of Luzon, Philippines (in coarse sand at four 

 fathoms) ; Cuming. 

 A very delicate close-ribbed species, the ribs being finer 



and more numerous as they approach the lip. 



Fig. 137. (Mus. Cuming.) 

 A well-marked variety of N. Gaiji described at Plate 

 XIII. Sp. 87.
