C. PSEUDOPRUNUM Pilsbry. PI. 55, figs. 13, 14, 15. 



Umbilicate, globose-depressed, the spire low-conic ; rather thin 

 but solid;, of a uniform light brown tint; surface nearly lusterless 

 above, somewhat shining below the periphery ; seen under a lens it 

 shows very minute close granules, which cover every part ; on the 

 apex and earlier whorls these points are arranged in oblique lines, 

 but on the last whorl such arrangement is scarcely traceable. 



Whorls 5? ; apex somewhat obtuse, its tip a trifle sunken ; suture 

 well-impressed. All of the whorls are convex, even the first one ; 

 the last descends somewhat in front. 



Aperture oblique, lunate-oval, livid-flesh tinted within ; entire per- 

 istome expanded, white, the columellar margin very broadly 

 expanding, curving around and overhanging half of the umbilicus. 



Alt. 21, greater diam. 26, lesser 21 mill. 



Northwestern Australia. 



This is the H. prunwn of Reeve, Conch. Icon., pi. 68, fig. 353, and 

 of Australian authors, Cox, (Austr. L. Sh., pi. 4, f. 6), of Brazier and 

 Tate, but it does not agree with the original H. prunum of Ferussac 

 in several respects. Of the latter Deshayes says : sa spire, tres 

 courte, se compose de six tours dont les premiers sont aplatis et eon- 

 joints; les suivants sont mediocrement convexes. And again : Toute 

 cette coquille est d'un brun marron uniforme. 



Ferussac's variety (Hist., pi. 26, f. 9) which is'more elevated, and 

 has an obscure subperipheral band, is certainly a Badistes near H. 

 dunkiensis, etc., and not a variety of prunum. 



The italics in the above quotation are my own. The flattened 

 inner whorls and chestnut-brown color would indicate that H. 

 prunum Fer. is a Badistes rather than identical with this Chloritis, 

 which has convex inner whorls and a light brown color. 



Fig. 14 represents a small portion of the last whorl, just below the
