The Macleay Museum contains four dead shells of this species, 

 which appear to resemble G. 2^elechy stoma, Tapp.-Can., purchased 

 from Mr. Goldie, who collected them in British New Guinea.

Type in British Museum. 



H a b. — Yule Island and Katow River (Brazier and D'Albertis) ; 

 St. Joseph River (Hedley) ; Fly River (Froggatt) ; Maclachie 

 Point, Krema district, foot of the Albert Range of mountains 

 (Goldie). 



An examination of a large series of shells in the possession of 

 Mr. Brazier induces me to consider G. taylorianus as a most 

 variable form. The following prominent varieties are linked each 

 to each by intermediate graduations : — 



(a) yulensis ; smaller than type, mottled with oblique irregular 



black dashes, which by transmitted light appear as trans- 

 lucent spaces. (Yule Island, J.B.) 



(b) katauensis ; encircled by black spiral bands. (Maclachie 



Point, Goldie.) 



(c) strabo ; a monochrome form with no clear mottled spaces ; 



approaches nearest to taylorianus. (Maclachie Point, 

 Goldie.)
