 devoid of it. Hedley has figured the anatomy.

Shell bandless, of a uniform light yellow, lip pure white. Differs 

 from the type in nothing but coloration.

This is a species of Sphcerospira very closely allied to H.fraseri; 

 and I would unite it to that species were it not for the blade-like 

 callus on the columella, a character not seen in the H.fraseri. It 

 has not been identified or mentioned by writers on Australian shells. 

 The type, Deshayes states, is a dead and discolored specimen. 



It is globose, about the size of H. pomatia ; Spire elongated, con- 

 oidal ; whorls 4J, slowly increasing, convex. Last whorl convex, 

 imperforate, deflexed below the periphery of the penultimate whorl, 

 and constricted behind the peristome. Surface smooth, with irreg- 

 ular growth-striae. Aperture relatively small, a little wider than 

 high, white ; peristome regularly arcuate, strongly reflexed, at the 

 columella bearing a tooth-like callus, and reflexed over the entire 

 umbilicus. Obliquity of aperture 55 to the axis. Color (as far as 

 preserved) wide bands and narrow lines of reddish-brown on a 

 whitish-yellow ground. A line of deeper color follows the suture.

H. ZEBINA Brazier. PL 47, fig. 89. 



Shell imperforate, rather solid, somewhat globosely-conical, whole 

 surface transversely granulated with lengthened grains (as seen 

 under the lens), towards the apex they become finer; pale straw- 

 yellow with numerous spiral chestnut lines and bands ; suture orna- 

 mented with a rather broad band ; spire rather large, broadly conical, 

 obtuse; whorls 5J, rather convex, last large, dilated and produced 

 in front, deflected above ; aperture diagonal, ovately-ltmate, whitish 

 within ; peristome straight, expanded and slightly reflected ; mar- 

 gins approximating, joined by a thin callus ; columellar light brown,
