144 PUPOIDES, AUSTRALIA. 



Form sinistralis. "All the specimens from Cassini Island 

 are sinistral; otherwise they resemble the normal form" (E. 

 A. Smith). In over 100 specimens of pacificus from seven 

 other localities, none were found sinistral. 



Buliminus (Chondrula) lepidula of Adams and Angas has 

 not been recognized by Australian conchologists of the last 

 fifty years. It came from well within the known range of P. 

 pacificus, and is, I cannot doubt, a synonym of that wide- 

 spread species. The description follows : 



Shell turrited, pupiform, umbilicate, thin, glossy, semipel- 

 lucid, corneous; whorls 5, strongly convex, longitudinally 

 striate. Aperture rotund-ovate ; peristome interrupted, white, 

 broadly reflected; outer lip provided above with a small, 

 white, 'tuberculiform callus. Length 2, width 1 line [about 

 4 : 2 mm.] (Adams and Angas) . 



West Australia : Sharks Bay. 



This little species differs from C. adelaidce in being more 

 semipellucid, shining and of a horn-color. The whorls, more- 

 over, are much more strongly convex (A. & A.}. 



26. PUPOIDES CONTRARIUS (E. A. Smith). PL 15, figs. 9, 10. 



Shell sinistral, rimate, brown-corneous, obliquely delicately 

 striate. Whorls 5%, convex, separated by a deep suture, the 

 last slightly wider than the penult, ascending in front. Spire 

 long, convex, pyramidal, subglobose at apex. Aperture about 

 % the total length; peristome white, expanded, margins 

 joined by a thin callus bearing a tubercle at the insertion of 

 the lip. Length 4.5, diam. 2 mm., aperture 1.5 mm. long 

 (Smith). 



West Australia : East Wallaby Island, Houtman 's Abrolhos 

 (Walker). Central Australia: widely distributed in the 

 Larapintine area, extending to Hart Range, southerly beyond 

 the Larapintine area to the Cretaceous hills about Sullivan 

 Creek.
