ZIZYPHINUS.— Plate V. 



is a very near representative, if not identical, of the 

 European Z. millegrantis. 



Species 33. (Mus. Cuming.) 



ZtzypHlNUS FLATUS. Zizyph. testa, late depresse conica, 

 aitraiitio-Jlavd, rufesceule palUdissime punctata, an- 

 fraclibus plano-declmhus, rude spiraliter liratis, liris 

 l/evibus, circa apicem granulatis. 



The yellow Zizyphinus. Shell broadly depressly co- 

 nical, orange yeUow, very faintly dotted with red, 

 whorls flatly sloping, rudely spirally ridged, ridges 

 smooth, granulated round the apex. 



Trochisjlavus, Anton, Zeitschr. fiir Malak. 1848. p. 105. 



Hab. Australia. 



It is quite possible that this may be a somewhat obscure 

 variety of a more characteristic species not yet discovered 

 in a typical state. 



Fig. 3-i. (Mus. Cuming.) 



The shell here figured, set apart in Mr. Cuming's col- 

 lection as a distinct species, is a rounded form of Z. scobi- 

 tiatus represented at Fig. 29. Both are from Bombay. 



Species 35. (Mus. Cuming.) 



Zizyphinus indistinctus. Zizypli. testa anguste co- 

 nica, pyramidali, olivaceo-Jlavd, purpureo-rufo tessel- 

 latim punctald, avfractibus subconvexo-declivibus, spi- 

 raliter lineari-liratis, liris Iceoibus, confertiusculis, 

 interstitiis subtilissime oblique clathratis. 



The indistinct Zizyphinus. Shell narrowly conical, 

 pyramidal, olive-yeUow,tessellately dotted with purple- 

 red, whorls somewhat convexly sloping, spii-ally line- 

 arly ridged, ridges smooth, rather close-set, interstices 

 veiy finely obliquely latticed. 



Trochus indistinctus. Wood, Ind. Test. Supp. pi. 6. f 41. 

 Zizyphinus indistinctus, Adams. 



Hab. New Holland. 



An olive-yellow erectly conical shell, sprinkled in a 

 tessellated manner with red dots. 



Fig. 36. (Mus. Cuming.) 



The shell here figured is a specimen of Z. decorutus in 

 which the grains are more distinct and papillary, the in- 

 terstices between them being still obliquely striated or 

 wi-inkled, whilst the ground-colour is a rose-lake, articu- 

 lated with pm-ple-black.
