146 HELIX-HADRA. 



The specimen from which my description was taken corresponds 

 exactly with Crosse's figures and description except that is is more 

 solid (not " tenuis "), and the umbilicus is not completely closed, 

 although the shell is completely adult. The species described and 

 figured by Cox as H. lor io liana is a distinct form. 



H. BROUGHAM: Angas. PL 34, figs. 2, 3. 



Shell narrowly perforate, conically globose, rather thin, obliquely 

 striated and obscurely minutely granulated, very pale brown above, 

 white below, with three narrow reddish brown bands one at the 

 suture, one above and one below the periphery of the last whorl ; 

 spire obtusely and depressedly conical; whorls 5J, slightly convex, 

 the last rounded, descending in front ; aperture oblique, circularly 

 lunate ; peristome slightly expanded and reflexed, the margins ap- 

 proximating, the columellar margin almost straight, dilated above, 

 and nearly covering the perforation. (Angas.) 



Alt. 10, greater diam. 12, lesser 10 lines. 



Port Lincoln, S. Australia. 



H. broughami ANGAS, P. Z. S. 1875, p. 390, t. 45, f. 4, 4a. 



Allied to H. cassandra, but more elevated, the columella straight- 

 ened, dilated and reflexed, nearly concealing the perforation. 



H. RUFOFASCIATA Brazier. 



Shell moderately unibilicated, giobosely depressed, thin, minutely 

 rugosely granulated ; pale brown, marked with dark chestnut spi- 

 ral bands ; whorls 5, slightly convex, regularly increasing, the last 

 large and inflated in front, roundly convex, below the periphery 

 the chestnut band becomes broader and runs spirally into the aper- 

 ture ; base white with chestnut brown around the umbilicus; aper- 

 ture roundly lunate, slightly angular, peristome thin, acute, margins 

 rather distant, the columellar margin dilated partly over the umbili- 

 cus, interior of aperture white or pink, the brown bands are seen 

 through the shell. (Brazier.} 



Alt. 7, greater diam. 12 , lesser 9f lines, 



Yardea, 360 miles north of Adelaide, S. Australia. 



H. (Hadra) rufofasciata BRAZIER, Proc. Linn. Soc. N. S. Wales, 

 i, p. 17, 1875. 



This fine shell approaches near to H. cassandra Pfr. It differs 

 very much from that species in having dark chestnut bauds above 

 and below with a large broad white band on the base, and chestnut
