XLVIII.— Ona Collection of Land-Shelis from New Guinea. 
By EpGar A. SMITH. 
[Plate IX.] 
THE specimens about to be enumerated and described were 
collected by Mr. W. Doherty chiefly at Kapaur, a moun- 
tainous region on the south-west coast of New Guinea, and 
at Takar, in the north-west of the island. The two forms of 
the new genus Jitropopsis and the new species of Perreria, 
Pupinella, and Adelomorpha are especially interesting. All 
the specimens are in the National Collection.
