794 MR. H. ADAMS ON NEW EXOTIC SHELLS. _[Nov. 15, 
tice subsinuata, intus margaritacea ; columella revoluta, acuta ; 
perist. simplex, rectum. 
PuHANETA EVERETTI, H. Ad. (Plate XLVIII. figs. 20, 20a, 206.) 
P. testa depresso-trochiformi, tenuiuscula, albida, epidermide pallide 
fulva tenui induta ; spira convexo-conica, apice obtuso, sublate- 
rali, sutura distincta ; anfr. 3, convexiusculis, rapide accrescenti- 
bus, striis obliquis obscuris, et striis nonnullis spiralibus, irregu- 
laribus ornatis, ultimo acute carinato, basi subconcavo, regione 
columellari excavato, concentrice conferte striato. 
Diam. maj. 8}, min. 73, alt. 6 mill. 
Hab. Siniwan River, Borneo ; attached to submerged logs (coll. 
H. Ad.). 
For a knowledge of this very distinct form of fluviatile mollusca 
we are indebted to Mr. A. Everett, who collected it in the neighbour- 
hood of Sarawak, Borneo. It appears, so far as can be judged from 
the shell alone, to be allied to the Valvatidee, in which family, there- 
fore, it may be provisionally placed. The two land shells below de- 
scribed were also found by Mr. Everett in the same locality.

tundato ; apertura parum obliqua, rotundato-lunari ; perist. sim- 
plici, recto, marginibus convergentibus, columellari arcuatim de-

mido, antice paulum ascendente, 2 mill. pone aperturam constricto, 
tubulum suturalem brevissimum gerente; apertura subobliqua, 
circulari ; perist. duplicato ; interno continuo, breviter porrecto ; 
eaterno patente, ad anfr. contiguum interrupto, supra perforationem

Genus HarGravesia, H. Ad. 
Testa subovata, polita, callo nitido obducta; apertura circulari ;

In this genus, which is in other respects similar to Pupina, the 
canal in the columellar margin is absent.
