Species allied to Sphcerospira from New Guinea. 



The following shells differ from Sphcerospira in much the same 

 way the latter differs from Badistes ; they are heavier, more solid, 

 with well-reflexed peristome. 



H. BROADBENTI Brazier. PL 25, fig. 100 ; pi. 39, figs. 75, 76. 



Shell large, umbilicated, subglobose with conoidal spire, heavy and 

 solid, deep chestnut or purplish brown with a yellowish band on 

 the upper and another on the lower surface of the body-whorl ; sur- 

 face smooth, not granulate ; lip pure white, reflexed all around, 

 dilated and partly covering the umbilicus. 



The shell is strong, with conoidal spire composed of nearly 6 whorls, 

 separated by sutures only slightly impressed. Surface lightly 

 obliquely striatulate ; color yellowish, with a broad dark band be- 

 low the suture, another forming an umbilical patch, and a very 

 broad dark girdle around the middle of the body-whorl. The spire 

 is lighter ; the dark bands coalesce on the latter part of the body- 

 whorl. Last whorl somewhat but not much deflexed in front. 

 Aperture oblique, wide, somewhat lunate, dark grayish-purple in- 

 side ; peristome well reflexed, pure white, dilated at the columella. 

 The back of the reflexed lip is white, the thin yellow epidermis 

 usually being deciduous there. The interior of the umbilicus is white.
