448 LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS, [June 1, 
before the umbilical region is entered ; but this latter character is not 
constant, as some of my specimens have the costulations continuous 
up to the umbilical region, as in filocinctum, so that it cannot, in the 
absence of the operculum, be looked to as a characteristic to distin- 
guish them; but the peristome, where the shell is adult, is a safe 
character. 
CYATHOPOMA (JERDONIA) SIVAGHERRIANUM, 0. sp. (Plate 
LI. fig. 17.) 
Shell pyramidal, turreted, thin, umbilicus very small and obscure, 
straw-coloured, glabrous, spirally lirate, apex attenuated, obtuse ; 
whorls 5, convex, the two lower with five spiral lines scarcely raised, 
antepenultimate with 2—4 lines, aperture vertical, circular ; peristome 
simple, thin, continuous or slightly interrupted at its apex ; opercu- 
lum double, with a sulcate margin, internally membranaceous, ex- 
ternally shelly, but only a little concave, as the margins are only 
slightly raised, nucleus central, transparent, moderate: length 4, 
inch, greatest diameter 51, inch. 
Sivagherry mountains, 3000 feet elevation. 
This comes nearest to J. blanfordi, but is very much smaller. 
CyaTHoroMa (JERDONIA) ATROSETOSUM, n. sp. (Plate LIL. 
figs. 18, 18a.) 
Shell umbilicated, ovate to subturbinate, spirally lirate, thin, 
semitransparent, whitish, furnished with a deciduous brownish 
vertically but inconspicuously striated epidermis, subobsolete, on 
some specimens; spire conical; whorls 5, rounded, furnished with 
numerous close, rather inconspicuous spiral lines, along which are 
numerous, rather distant, patent or suberect long black lines; umbi- 
licus more or less open, with a more or less prominent keel at its 
entrance, inconspicuously ribbed or smooth within; aperture sub- 
vertical, circular; peristome single, subdouble or double, entire or 
with the outer margin beautifully crenated; operculum subdouble, 
externally white and shelly, and a little concave from the margins 
being raised, multispiral, with a large central transparent nucleus, 
internally membranaceous, convex, yellowish, shining: length +, 
inch, greatest diameter /y to =; inch. 
South-Canara ghats, 3000 feet elevation; Anamallays, higher ranges. 
The peristome, the umbilical region, and even the shape of the shell 
are very variable, both in the 8. Canara and Anamallay specimens. 
CYATHOPOMA (JERDONTIA) ELATUM, n.sp. (Plate LIT. fig. 19.) 
Shell narrowly umbilicated, ovato-pyramidal, spirally lirate, epi- 
dermis brownish, furnished with distant prominent vertical strize 
and a fine very minute striation also present between them; spire 
conical, apex subacute, sutures deep; whorls 5, rounded, furnished 
with numerous rather close spiral costulations, continuous down to 
the ribbed umbilical region; aperture vertical, circular; peristome 
double, the inner one continuous, quite entire or very inconspicuously 
crenate, outer more or less expanded and reflexed, continuous all 
round except at the left apex, where it comes into contact with the
