450 LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS. [June 1, 
subcircular ; peristome thick, double, the inner one pearly white in- 
side and crenated (but less prominently than in C. hirsutum), outer _ 
one dilated on its outer and lower margins, particularly at its right 
apex and left base, and somewhat reflexed, more or less sinuate (but 
not with prominent crenations as seen in C. hirsutum); operculum 
double, externally concave, shelly, with a small transparent central 
nucleus: height 3 inch, greatest diameter °; inch. 
Anamallay mountains, moist woods on the banks of the Sholayar, 
a large river, 2000 fect elevation. 
Nearly allied to Mychopoma hirsutum, but not furnished with the 
same curious, raised, thread-like epidermis, except within the umbili- 
eus, and without any umbilical fringe; it is, besides, a smaller, dif- 
ferently shaped shell, and differs in other minor points, as indicated 
above. It has exactly the operculum of MV. hirsutum, which, as before 
stated, does not differ from that of Cyathopoma wynadense; and 
some other forms that I refer to this Jerdonia section of Cyathopoma 
and Mychopoma cannot be kept up. 
CyaTHOPOMA (JERDONIA) CEYLANICUM, n. sp. (Plate LII. 
fig. 20.) 
Shell prominently umbilicated, turbinate, with a conical blunt 
apex, inconspicuously spirally lirate, epidermis glabrous, yellowish, 
with obliquely vertical bright chestnut bands and a very inconspi- 
cuous vertical striation; whorls 5, convex or subangular, the lowest 
with two inconspicuous lines or ribs along the region of the peri- 
phery, and sometimes a third still more obsolete between them and 
the suture; penultimate with two carinations, the lower one almost 
touching the suture and sometimes obsolete, antepenultimate incon- 
spicuously unicarinate ; umbilicus somewhat angled at the entrance, 
smooth within; aperture nearly vertical, circular; peristome sub- 
double, continuous, inconspicuously angled or crenated at the exit 
of the two carinations of the lowest whorl; operculum as in C. ana- 
mallayanum: length + inch, greatest diameter j inch. 
Ceylon, common in woods about the Rambaddi waterfalls. 
Very like C. anamallayanum, but distinguished under the lens by 
its much more prominent though still inconspicuous carination ; it is 
also of greater diameter with refereuce to its length. 
CYATHOPOMA LATILABRE, n. sp. (Plate LIII. figs. 28 and 29.) 
Shell deeply and prominently umbilicated, turbinato-globose, 
glabrous or subglabrous, epidermis of a pale yellowish brown colour, 
with oblique vertical dark chestnut-coloured bands and a minute 
vertical striation, white beneath the epidermis; spire conical, apex 
subacute ; whorls five or six, the lowest smooth in its upper half near 
the suture, in the region of the periphery surrounded with three 
rather prominent carinations with a smooth space between them and 
the umbilical region, the penultimate and antipenultimate with 
generally two less prominent lines or ribs; lowest whorl cylin- 
drical, slightly descending with an inconspicuous swelling followed 
by a slight contraction just in front of the reflexed peristome; the
