 tured with irregular growth-wrinkles, and either conspicuously or 

 lightly malleated spirally. Whorls nearly 5, slightly convex, the 

 last inflated. 



Aperture long-ovate, white, faintly -brown-tinted, or with gray 

 markings within ; peristome broadly reflexed, especially below, 

 white ; columellar margin dilated, free. Columella having a rather 

 angular fold above.

The malleation is inconspicuous in some shells, and the character- 

 istic olive-brown blotches are sometimes wanting or very sparse. 

 Such specimens resemble P. morosus, but may be known by the 

 larger size, more oblong aperture, flattened basal lip, etc. In a series 

 of fifteen specimens before me, no two are alike in markings. 



P. MOROSUS (Gould). Pi! 41, figs. 78, 79. 



Shell compressed-umbilicate, rather acutely ovate, thin, pure white 

 throughout. Surface but slightly shining, rudely, coarsely and irreg- 

 ularly wrinkled longitudinally, slightly malleated in places. Spire 

 rather slender, the apex obtuse, the earlier whorls punctate. Whorls 

 5, moderately convex, the last inflated. 



Aperture large, ovate, vertical, white ; the peristome broadly re- 

 flexed and recurved at the edge, its face convex ; columellar margin 

 dilated, the columella having a rather strong fold above. 



Alt. 50, diam. 26 ; aperture with peristome 33 mill. 



Alt. 44, diam. 23J ; aperture with peristome 30 mill.
