H. INFORMIS Mousson. (Vol. VI, p. 160). PI. 51, figs. 27, 28. 



Two figures are here given, drawn from specimens received from 

 Dr. J. C. Cox. It is the largest species of Sphcerospira. The sur- 

 face shows, under a strong lens, a beautiful sculpture of close, fine 

 wavy wrinkles, having a general direction parallel to the shell's 

 axis. 



One of the specimens figured is from Port Mackay, the other from 

 Mi. Dvyander, Queensland. 



H. RAWNESLEYI Cox. (Vol. VI, p. 165.) 



The figures given in Vol. IX are drawn from a specimen 

 received from Dr. Cox. It is a notably solid shell, with numerous 

 whorls, somewhat flattened base, dark-edged lip and nearly covered 

 umbilicus. Under a strong lens the upper surface shows a sculp- 

 ture of most minute, close wrinkles, generally parallel to the axis, 

 but criss-cross in places. The specimen is from Mt. Dryander, 

 Queensland. 



H. INCEI Pfr. (p. 167). 



As varieties Hedley includes bayensis Braz., lessoni Auct. aitree- 

 densis, Brazier. (See P. L. S. N. S. W. (2), vi, p. 556). The lat- 

 ter was collected by Mr. Mousson at Rockhampton. 



H. AUREEDENSIS Brazier (p. 169). PL 54, figs. 7, 8, 9. 



This hitherto unfigured species is depressed, solid, dark colored 

 with a few darker bands, a white sutural line and a light yellow, 

 ill-defined umbilical patch. Aperture livid inside; the slightly 

 expanded, thin lip is white Qn both face and reverse. Under a lens 

 the surface shows fine 'spiral strise. 



Section Xanthomelon Mts. 



H. PERINFLATA Pfr. (Vol. VI, p. 183). PI. 58, fig. 1. 



This shell was first obtained by Mr. F. G. Waterhouse in the 

 MacDonnell Ranges, Central Australia, when accompanying John 

 Macdougall Stuart in his exploration across the continent, and was 

 described by Pfeiffer in 1863 from the specimens there procured. 

 It was the prevailing species collected by Mr. Helms, and speci- 

 mens were taken from Mount Illbillee on the Everard Range, west- 

 ward to the Victoria Desert. 



Those taken at the commencement of the journey answer most 

 closely to the description transferred by Dr. Cox to his Monograph
