spira obtusaj conoidea; anfractus 4, convexiusculi^ rapide 

 accrescentes, iiltimus basi subcompressus ; apertura per-

This remarkable shell resembles a dwarf H. hcemastoma 

 in sliape ; it is of a porcelain white except at the aperture, 

 which has a broad reflexed lip of a deep brown-black hue, 

 both within and without. It is a very interesting species, 

 indicative of the Indian affinities of the New Guinea 

 fauna. A single specimen was taken in August 1849, on 

 a bread-fruit tree in Brumer Island, S.E. coast of New 

 Guinea.
