The colour of the oiïly spécimen is light corneous, but its shape is quite typical.

The spécimens mentioned above are typical as far as concerns the first 3 records ; the 

 last 2 form links to the next colour variety, by their upper whorls being not spirally banded, 

 but more or less flamed or spotted, with the exception of the rosy top ; even a few spécimens 

 are quite typical, without any spots ; the majority of the spécimens seems to belong to var. oc 

 of Tapp. Canefri, though he does not mention that the base of shell has always at least 

 one infra-peripheral brown band, this variety came from the following localities : 



Digul River, 1904, (Dr. Koch leg.); Van der Sande River, Sept. 10, 1909; Bivak Island, 

 Sept. 15, 20, 22, 25, 1909; Sabang, June 28, i9o7;.Resi Ridge, Aug. 30, 1907; Van Weel's 

 Camp, May 29, 1907. 



It will be observed from many of the dates, that spécimens of the type and var. were 

 collected together, and so the value of the variety is not more than that of our common 

 garden-snails.
