 f. 5 (shell) ; t. vi, f. 6 (Anatomy). 



Closely allied to H. ridibunda, H. taumantias and H. brazierce ; 

 but smaller than either, more distinctly carinated, and with a very 

 broadly reflexed columellar lip. 



H. AURORA Pfeiffer. PL 11, figs. 10, 11, 2. 



Umbilicate, turbinate-depressed, rather solid, irregularly striatu- 

 late, little shining, unicolored brown ; spire short conoidal, apex 

 minute, rather acute. Whorls 4$, a little convex, the last carinated 

 at the periphery, scarcely descending in front, a little convex below. 

 Aperture oblique, wide, depressed-lunar, rosy and with a pearly lus- 

 ter inside ; peristome pale rose or lilac-flesh tinted, the margins con- 

 verging, upper lip horizontal, expanded, outwardly subefFuse ; basal 

 lip slightly arcuate, reflexed; columellar lip dilated, nearly closing 

 the umbilicus. Alt. 17, greater diam. 30, lesser 24 mill. (Pfr.)

From the localities last given, Tapparone Canefri received a vari- 

 ety which is larger, without a peripheral carina, the aperture wide, 

 peristome dilated, well reflexed, white ; measuring, alt. 20, greater 

 diam. 38, lesser 30 mill. 



Specimens from Sorong measure : alt. 16, greater diam. 28, lesser 

 22 mill. 



H. .EROPE Smith. Uvfigured. 



Shell rather widely umbilicated, depressed trochiform, obtusely 

 angulated at the periphery, pallid or whitish-brown, encircled with 

 a narrow reddish zone about the middle. Whorls 5, a little con- 

 vex, rather slowly widening, obliquely striated with delicate growth- 

 lines ; last whorl carinated, the carina sensibly disappearing toward 

 the aperture, equally convex above and below, shortly descending in 

 front, about the middle minutely rugose. Aperture transverse, 

 lunate, whitish or pale lilac within ; peristome white, dilated and re- 

 flexed, the columellar margin widely expanded. 



Alt. 15, greater diam. 23, lesser 19 mill. (Smith.')
