suture, magnified to the same extent as fig. 12 which represents the 

 sculpture of H. coxeni Cox. It will readily be seen that the two 

 are quite distinct. 



This form might be referred to H. pelodes Pfr. were it not that 

 the color and measurements given by Pfeiffer do not correspond with 

 it, and Pfeiffer himself considered pelodes a synonym of prunum 

 Fer. 



The synonymy of the true H. prunum Fer. is correctly given in 

 Manual vol. VI, p. 135. Pfeiffer's figures of prunum (Conchyl. 

 Cab.), are copied from Ferussac, as are also Tryon's (Manual vol. 

 Ill, pi. 50, figs. 25, 26). Fig. 26 represents the " variety " with a 

 peripheral dark band. 



C. COXENI Cox. PI. 55, figs. 10, 11, 12. 



This species is readily distinguished from the H. prunum of 

 Australian authors, by the much more separated granules or hair- 

 points, which are, moreover, obviously arranged in oblique lines, a 

 disposition not found in H. prunum. The umbilicus is larger and 

 more expanded in coxeni than in prunum, although the shell is 

 smaller. 



A more minute granulation becomes visible under a strong lens, 

 covering the surface between the hairs or hair-scars. The figure 

 represents a small portion of the surface of the last whorl, just below 

 the suture. I am indebted to Dr. Cox for specimens of this and the 

 last species. 



C. MICHOLITZI Mollendorff. 



Shell half-covered umbilicate, depressed-globose, horny-buff 

 colored; transversely striatulate, having short hairs standing in 

 regular series, 24 in 1 square millim. Spire little elevated, above 

 flattened, the apex immersed. Whorls 4, convex, separated by a 

 rather deep suture, the last whorl inflated, suddenly and shortly 

 deflexed in front, contracted behind the aperture, almost crested, the 

 base rather swollen, obtusely angled around the umbilicus. Apert- 

 ure oblique, broad truncate-oval ; peristome broadly expanded, 

 slightly reflexed, sublabiate, buff, thecolumellar margin very broad, 

 white-calloused, forming an indistinct angle with the basal lip. 



Alt. 11-5, diam. 18 mill.; aperture, width 12*5, length 10, alt. 6'5
