This remarkable sbell resembles a dwarf H. hcemastoma 

 in sbape ; 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 ia August 1849, on 

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

 Guinea.
