Hah. — German New Guinea. 



The genus Coliolus was founded by Tapparone - Canefri for 

 C. Arfakiensis, the other known species being Canefriana, Smith, and 

 Weiskei, Fulton. C. thrix therefore forms an interesting addition to this 

 restricted genus, in which, judging from shell characters, it is best 

 included. The sculpture and arrangement of the hairy epidermis 

 resemble those features as described in C. Arfakiensis, but the shells 

 now dealt with have only 9 as against 1 1 whorls, and the general 

 form, as will be seen from the accompanying figures, is quite diiferent. 

 This and the preceding species were received by Mr. Bednall of 

 Adelaide from German New Guinea, and were kindly forwarded by 

 him to the writer for description.
