This beautiful snail is of a brightly shining yellowish or 

 greenish horn colour. The whorls of its spire are small, 

 but the body whorl, whilst preserving a wide diameter 

 throughout, gradually increases in trumpet-like manner to 

 the round mouth. It belongs to the same group with H. 

 olivetorum and JI. nitida, and is allied to the Austrahan 

 H. ptycomphala. It occurs about the roots of trees in the 

 Frankland and Lizard Islands.

 41, min. 4, alt. 3 miU. (Mus. Brit. & Geol.) 



This curious little snail, resembling a roUed-up lulus,
