Species 7. (Fig. a, b, Mus. Cuming.) 



ZiZYPHlNVS ORXATUs. Zkypli. testa oblique conoided, 

 bosi dilatatd, anfract'tbua convexis, denai- f/rano-strialk,

The ornate Zizyphinus. Shell obliquely conoid, 

 dilated at the base, whorls convex, densely grain- 

 striated, last whorl more sloping, obtusely angled at 

 the peripheiy, grains stronger ; yellowish, obliquely 

 arcuately clouded and flamed with flesh-red, base 

 tinged with orange, sometimes dot-articulated with 

 red.

 Zizi/phiiiHS oniritus and t/ebidosus, A. Adams. 



Hab. Torres Straits, North Australia ; Ince. 



This species resembles the following in general aspect, 

 but it is well characterized by Lamarck in being grain- 

 striated and dilated at the base. In i. unicus the last 

 whorl is conspicuously rounded. 



Species S. (Mus. Cuming.) 



Zizyphinus unicus. ZizijpU. testa oblique conoided, 

 basi venlricoso-rotimdatd, anfraclibus rotnndatls, dense 

 liralo-striatis, parum granatis, basi lavigatd, circula- 

 riter incisd ; albidd vel flavescente, sanguineo-rufo sub- 

 remote Jlammatd , ad jieripheriam conspicue articulatd. 



The cnique Zizyphinus. Shell obliquely conoid, ven- 

 tricosely rounded at the base, whorls rounded, densely 

 ridge-striated, but little grained, base smooth, cii-cu- 

 larly engraved ; whitish or yellowish, rather distantly 

 flamed with blood-red, conspicuously articulated at 

 the peripheiy. 



DuNKER, Moll. Japonica. 



Hab. Japan; A.Adams. 



Vei-y closely allied, and very simOar in painting, to the 

 Australian Z. ornutus. The surface is much less grained, 

 the last whorl of the shell is ventricosely rounded, and the 

 periphery is encii-cled by a well-defined articulated band of 

 rather distant red spots. 



Species 9. (Fig. a, b, 'Sim. Cuming.) 



Zizyphinus, si-eciosus. Zizyph. testd erecto-conicd, sub- 

 pyramidali, ad basin depresso-rotandatd, anfraclibus 

 subcoiicavo-declivibus, undique rjrano-liratis, Uris te- 

 nnibus, lira parvd laviuscidd intermnienle ; flavescenle- 

 albidd, piirpureo-rufu obscure tessellatd et punctato- 

 yemmatd, basi purpureo-punctatd, callo centrali usln- 

 lato-aurardio tincto. 



The beautiful Zizyphinus. Shell erectly conical, 

 somewhat pyramidal, depressly rounded at the base, 

 whorls rather concavely sloping, grain-ridged through- 

 out, ridges tine, with a rather smaller smooth ridge 

 coming between ; yellowish white, obscurely tessel- 

 lated and dot-gemmed with puiqole, base purple- 

 dotted, central callosity tinged with burnt orange. 



Adams, Pro. Zool. Soc. 18.54, p. 38. 



Hab. Moreton Bay, Australia ; Strange. 



The colouring of this tine species is very promiscuously 

 distributed. Paint tessellated blotches, accompanied by a 

 general sprinkling of dots in livid purple, are seen through- 

 out, sparse and irregular. 



Species 10. (Mus. Cuming.) 



ZlZY'PHINUS KOBILIS. Zizypli. testd acute conicd, ad 

 basin angulatd, anfractibiis plano-declivibus, valide 

 grano-liralis, lira basali majure, subprominente ; flaves- 

 cente, ferrugineo-rufo tessellatd, Uris alternatiin pur- 

 pureo-roseis. 



The NOBLE Zizyphinus. Shell sharply conical, angled 

 at the base, whorls flatly sloping, strongly grain- 

 ridged, basal ridge larger, rather prominent ; yel- 

 lowish, tessellated with rust-brown, ridges alternately 

 puiijle-rose. 



Trochus nobilis, Philippi, Kuster, Conch. Cab. p. 86. 

 pi. 15. f 6. 



Hab. Swan Eiver. 



An exquisitely gemmed species, in which the ridges are 

 alternately coloured purple-rose, both on the upper sur- 

 face of the shell and at the base.
