H. bellenden-kerensis BRAZIER, P. Z. S. 1875, p. 32, t, 4, f. 4. 



The locality given is near the Endeavor River. The three spec- 

 imens seen by Mr. Brazier are of the same color. 



H. PARSONI Cox. PL 35, figs. 11, 12, 13. 



Shell with a deep, open umbilicus, globosely conical, uniform dark 

 purplish chestnut on the body-whorl, the spire becoming yellowish 

 - with fine indistinct chestnut lines, suture bordered by a distinct nar- 

 row white line ; lip dark. 



The shell is compact, elevated, microscopically striated spirally 

 like most species of Sphcerospira. Spire elevated, lighter than the 

 dark chestnut body-whorl, and having spiral brown lines. Suture 

 superficial. Whorls 6J, slightly convex, the last deflexed in front, 

 somewhat flattened beneath. Aperture quite oblique, purplish with 

 a satin-like luster within, becoming darker on the lip, which is 

 broadly expanded, triangularly dilated at the columella, overhang- 

 ing the umbilicus, more than half concealing it.

Flatter beneath than H. blomfieldi, differently colored, and differ- 

 ing fundamentally in being umbilicated. It is like H. lessoni in 

 having the body-whorl dark, spire lighter, but it is a decidedly more 

 elevated shell, with more widely expanded dark edged lip. It does 

 not have the color-pattern of H. rockhamptonensis, nor is the base so 

 flat as in that form. 



H. LESSONI Pfeiffer. PI. 33, figs. 61, 62, 63. 



Shell half-covered umbilicate, depressed globose ; body-whorl dark 

 chestnut colored, the spire yellowish or lighter brown, often showing 

 spiral brown lines ; lip expanded, becoming lighter toward its white 

 edge; suture with an inconspicuous pale margin. 



The shell is compact, base depressed, spire convex-conoidal. The 

 body-whorl is typically of a uniform purplish-chestnut color, but 

 specimens occur in which it is of a lighter brown, with numerous 

 rather obscure darker bands and lines. The base in these banded
