On a new Species of Chioritis. 157 
AXIT].—Deseription of a new Species of Chioritis from the 
Loo-Choo Islands. By G. K. Gupz, F.Z.8. 
Chloritis (s. s.) oshimana, sp. n. 
Shell narrowly but deeply umbilicated, discoid, dark 
corneous brown. Spire flattened, apex sunk below the level 
of the spire, suture deep. Whorls 43, convex, increasing 
rather rapidly, the last twice as wide as the penultimate, 
descending rather deeply in front and suddenly widened 
towards the mouth; the embryonal 14 whorls smooth, the 
last 3 densely covered with stiff, persistent, golden-brown 
hairs disposed in oblique rows at right angles to the lines of 
growth; the spaces between the rows densely papillate. 
Aperture oblique, obovate. Peristome thickened and shortly 
reflected, fuscous ; margins approaching, united by a raised 
flexuous ridge; parietal callus densely covered with horizontal 
rows of papille ; upper margin ascending shortly at first, then 
descending, straight ; outer margin rounded, basal straight ; 
columellar straight, forming an obtuse angle with basal, 
slightly dilated over the narrow deep umbilicus. Inside the 
mouth occurs an elongated swelling just behind the peristome, 
and corresponding with it a well-defined pit at the base of the 
shell near the junction of the basal and columellar margins. 
Diam. maj. 19°5, min. 16 ; alt. 10 mm.

(Mr. Hirase, no. 354.) 
Chloritis oshimana resembles C. cheratomorpha, Tap., from 
New Guinea, but it is smaller and the apex is not so deeply 
sunk; the aperture is more oblique and the hairs are longer 
and much more sparsely distributed. The smallest specimen 
Chloritis oshimana: figs. 1-3, three different views; fig. 4, transverse 
section of spire, showing the sunken apex. 
is more depressed than the others, and the swelling inside the 
aperture with the corresponding pit outside is almost obsolete. 
Four specimens were received.
