 whiteleggei Braz., HEDLEY, Kec. Austr. Mus. 1, no. 7, p. 138, t. 21,

Var. BALLI Brazier. PL 19, figs. 59, 60, 61. 



Shell depressly globose, often eroded; whorls rounded. Spire 

 slightly raised, base rounded, umbilicus narrow but exhibiting the 

 previous volutions. Alt. 6, greater diam. 11, lesser 10 mill. 



Summit of Mount Ledgbird. 



Var. LEDGBIRDI Brazier. PL 19, figs. 62, 63. 



Shell globosely conoid, whorls rounded, spire elevated, base 

 rounded, aperture subcircular, umbilicus narrow. 



Diam. maj. 8, min. 7, alt. 6 mill. (Hedley.) 



Western flanks of Mount Ledgbird. 



The type specimens of this species and its varieties are in the 

 Australian Museum. 



I have copied the figures from Mem. Austr. Mus., although they 

 caricature rather than illustrate the species. Figs. 53, 54, 55, are 

 drawn from a specimen before me (No. 62,421 of the Acad. Mus.), 

 supplied by Dr. James C. Cox. The sculpture and coloring of this 

 specimen correspond to Hedley's most excellent description of 

 whiteleggei; the spire is plane; umbilicus between one-sixth and 

 one-seventh the diameter; alt. 6, greater diam. 122, lesser 10 mill. 



Although rather aberrant, I am still disposed to group this spe- 

 cies in Charopa. 



(3. Species of Tasmania and S. Australia.) 



P. ANTIALBA Beddome. PL 36, figs. 23-26. 



Shell thin, transparent; contour, a sphere truncated at the poles, 

 deeply concave above and below, the umbilical excavation deepest. 

 Color brown, the shade of dry dead leaves, streaks of slightly 

 lighter shade represent the flame painting of other species.
