DESCRIPTIONS OF NEW LAND SHELLS— HEDLEY. 
47 
Flammulina abdita, n. sp. 
(PL xi., figs. 10, 11, 12.) 
Shell very small, thin, translucent, moderately umbilicated, and 
depressed. Colour raw umber, paler on the earlier whorls and 
purplish on the apex. Whorls.three and a half, rather rapidly in- 
creasing, rounded, channelled at the suture and slightly descending 
at the aperture. Sculpture, — the whorls are crossed at irregular 
intervals by numerous lamellate ribs, rising on the periphery into 
thin recurved plates but obselete on the last quarter whorl ; between 
and parallel to these ribs are fine raised hair-lines, which are cut 
by close, fine, faint, irregular spiral incised lines. At a whorl and 
a half the limit of the embyronic shell is sharply indicated by the 
commencement of the above described sculpture, the earliest 
whorls being smooth except for close, fine, incised, spiral lines ; 
on the apex is a small pit. Umbilicus about a quarter of the 
shell’s diameter, exposing the earlier whorls. Aperture ovate 
lunate, slightly oblique ; peristome sharp, straight, except where 
reflected on the columella margin, no visible callus on the inner 
side. Major diameter, l*5j minor, 1*3; height -8 mm. 
Type . — Queensland Museum. 
Hab . — Collected by Mr. A. Giulianetti, in October, 189G, at a 
height of 12,200 feet on Mount Scratchley, British New Guinea. 
This species possesses close affinities to the wide-spread Aus- 
tralian (H.) paradox a, Cox, from which the novelty differs by its 
less developed ribs, less elevated spire, wider umbilicus, and 
smaller size. Pilsbry’s figure of JEndodonta acanthimda , Crosse, 
suggests to me that that New Caledonian species should be 
grouped herewith. The few whorls and the aspect of the em- 
bryonic shell induce me to place this Papuan atom in Flammulina 
rather than in Endodortta , but with our present imperfect know- 
ledge of these groups such classification can only be considered 
provisional. 
SlTALA ? SUBLIMIS, 71. Sp. 
(Plate xi., fig. 4, 5, 6.) 
Shell small, thin, translucent, depressedly turbinate, narrowly 
perforate. Colour tawny olive. Whorls three and a half, gradually 
increasing in diameter, rounded. Suture impressed. Sculpture, — 
the otherwise smooth shell is everywhere crossed by extremely 
fine, close, transverse hair-lines, more prominent above, almost 
effaced beneath. Umbilicus extremely narrow, elliptical, exposing 
only the previous whorl. Aperture roundly lunate, not descend- 
ing, oblique ; lip sharp, straight, except a slight reflection at the 
columella; callus on body whorl thin, deposited in transverse 
streaks. Major diameter, 2*4; minor, 2; height, 1*5 mm. 
Type . — Queensland Museum.
