114 THE LAND MOLLUSCAN FAUNA OF BRITISH NEW GUINEA, 



var. rosselensis, var.nov. 



Whorls more convex, colour rose with apex and callus yellow. 

 Diam. maj. 9, min. 8, alt. 7 mm. 



H a b. — Rossel Island (Kowald and Belford) ; abundant. 



This species is evidently a dominant form, and may be expected 

 under one of its aspects from any island in the Louisiades and 

 neighbouring archipelagos. 



Var. sinus is almost entitled to specific rank ; it makes a distinct 

 advance towards II. stanleyi, and in another direction var. ?'ossel- 

 ensis approaches H. woodlarkensis.
