Species 63. (Mus. Cumiug.) 



Zizyphinus Zebuensis. Zizypli. testd obeso-conicn, al- 

 bidd, pcdlidi cterulesceute-viridi variegatd, anfractibus

 iuras minute crenulatis, liris Icevibns, suhacutis. 



The Zebu Zizyphinus. Shell stoutly conical, whitish, 

 variegated with pale blue-green, whorls rounded, 

 closely finely ridged throughout, minutely crenulated 

 below the sutures, ridges smooth, rather sharp. 



Adams, MS. in Mus. Cuming. 



Hab. Island of Zebu, Philippines ; Cuming. 



The ridges of this little species are unusually fine and 

 sharp, with no indications of granules. 



Species 64. (Mus. Cuming.)

 griseo-albidd, lineis iemiibus candeo-nigricantibus in- 

 terruptis cinctd, ad suturas minute articulatd, anfrac- 

 tibus plano-declivibus, spiraliter tenuiliratis, inter- 

 stitiis minute crenulato-striatis. 



The interrupted Zizyphinus. Shell erectly conical, 

 greyish-white, encii-cled with fine blue-black inter- 

 iiipted lines, minutely articulated at the sutures, whorls 

 flatly sloping, spirally finely ridged, interstices mi- 

 nutely crenulately striated.

 Zizyphinus interruptus, Adams. 



Hab. ? 



A very tlistinct erectly-conical shell, painted in an elabo- 

 rately tessellated manner. 



Species 65. (Mus. Cuming.) 



Zizyphinus DECUSSATUS. Zizyph. testd subacute conicd, 

 ad basin fumidiusculd, albidd, vivide viridi macidatd

 tenni: grano-liratis, ad marginem basalem decussatis et 

 squamatis, siduris anguste impressis. 



The DECUSSATED Zizyphinus. Shell rather sharply coni- 

 cal, a little swollen at the base, white, spotted and 

 variegated with bright-green, whorls flatly sloping, 

 spirally finely grain-ridged, decussated and crenu- 

 lately scaled at the basal margin, sutiu'cs narrowly 

 impressed. 



Adams, Pro. Zool. Soc. lS51,p. 167. 



Hab. Island of Mindoro, Philippines (in coarse gravel, 

 at the depth of twelve fathoms ) ; Cuming. 



A very elegant little species, in which the granules at the 

 basal margin of each whorl and on the under surface of 

 the shell are transformed into scales.
