Ziziphinus legrandi Ten.-Woods, Proc. & Rep., Roy. Soc. Tas- 

 mania, 1875, p. 154. 



A small smooth-ribbed form, allied, according to Tenison-Woods 

 to Z. incertus Rve. 



C. iNCERTUM Reeve. PI. 17, fig. 37. 



This reversed species is known to me only by Reeve's illustration 

 (pi. V, fig. 28). The accompanying page of text is lacking in the 

 copy of the Iconiea in the Academy library. 



C. ALLPORTi Tenison- Woods. PI. 66, fig. 22. 



Shell small, conical imperforate, solid, white, the 6 or 7 whorls en- 

 circled by series of granules, 6 in number on the penultimate and 

 up2)er surface of last whorl, the beads distinct, rounded ; base with 

 about 10 scarcely granulous concentric Wvve. Spire conic, its outlines 

 straight ; apex acute, suture linear ; body-whorl angular at periph- 

 ery, a little convex beneath ; aperture quadrangular, with a couple 

 of rather strong riblets inside the upper outer lip; basal lip thick- 

 ened ; columella very oblique, a trifle straightened in the middle, 

 rounded. Alt. 7, diam. 6^ mill.

]My specimen described above is probably not fully adult. The 

 whorl is a trifle deflexed at the aperture, as in C. legrandi; and 

 like that shell, there are a pair of rather strong spiral lirse within 

 the aperture, which are rather strong near the upper outer lij). Teni- 

 son-Woods describes his shells as having the whorls rather convex, 

 periphery rounded, inter-liral spaces obliquely striate, aperture bi- 

 . dentate below, alt. 11, diam. 9 mill., — characters lacking in my 

 specimen, owing, probably to its immaturity and slightly worn 

 condition. 



C. jucuNDUM Gould. PL 66, figs. 26, 27, 28. 



Shell small, solid, low conical, composed of about six conical 

 whorls, with a slight vertical portion at base ; the whorls girdled with 

 fine, uniform, beaded lines, the alternate ones being generally smaller, 

 sometimes even not beaded, and the two basal ones surrounding the 

 vei'tical portion being larger ; base a little convex, similarly 

 sculptured with about twelve concentric lines, gradually diminishing 

 from the center to the circumference ; the umbilical region color-
