446 LIEUT.-COL. BEDDOME ON NEW LAND-SHELLS. [June l, 
gaping mouth, so that it is externally very concave; they have 
otherwise the same structure and the same diaphanous nucleus as in 
Jerdonia, and the two are only modifications of the same structure. 
Further on I describe three species of this section, in which the outer 
shelly portion is completely arched over, leaving only a small hole in 
the centre, so that the operculum is very convex, or papilliform, 
externally. 
CyaTHOPoMA (JERDONIA) BLANFORDI, n. sp. (Plate LII. fig. 
13.) 
Shell thin, umbilicated, pyramidal, turreted, straw-coloured, apex 
attenuated and subacute; whorls 6, sutures prominent, all the 
whorls, except the two small apical ones, prominently carinated ; 
carinations two to three on the third whorl, three to five on the 
fourth, five to seven on the lowest, those about the umbilical region 
rather distant; umbilicus pervious; aperture circular; peristome 
thin, single, continuous, inconspicuously crenulate ; operculum as in 
the last species: length 4 inch, greatest diameter =; inch. 
Tinnevally mountains, 4000 feet elevation. 
I have a closely allied species from Ceylon, Jerdonia dickoyensis 
(Nevill, MS.); it is rather smaller, with a finer carination, and 
much smoother about the umbilical region ; and I think specifically 
distinct. 
CyaTrHoroma (JERDONIA) ALBUM, n.sp. (Plate LIT. fig. 14.) 
Shell widely umbilicated, depresso-turbinate, furnished with a 
chalky white or whitish brown epidermis, having a minute vertical 
striation, which is early deciduous, or only present in patches, the 
shell beneath being of a peculiar shining white horny texture; spire 
conoidal, apex subacute; whorls 4—5, spirally lirate, the lowest with 
four to five, the penultimate with three ribs or lines, more promi- 
nent before the loss of the epidermis; the umbilicus prominently 
spirally ribbed within; aperture circular, oblique ; peristome thin, 
simple, continuous, slightly angled at the inner base at the termina- 
tion of the first rib round the umbilical region; operculum exter- 
nally very concave, with the margins of the outer shelly layer much 
raised but straight and not at all arched, multispiral, with a small 
transparent nucleus: length =; inch, breadth +4, inch. 
Yellagherry mountains, Salem district, 2500 feet elevation; Siru- 
mallay hills, Dindigal, 3000 feet elevation; also, I believe, in 
Ceylon, as I have several poor specimens of what appears to be 
quite the same shell, collected at Dimbola, in the central provinces. 
This shell is evidently allied to Cyathopoma kalamalliense (Blan- 
ford), which I have not seen; and I think that I should have con- 
sidered it that species, only Mr. Blanford, who has seen my speci- 
mens, pronounced it distinct. 
CyaTHorpoMA (JERDONIA) ANAMALLAYANUM, 0. sp. (Plate 
LI. fig. 15.) 
Shell umbilicated, turbinate, with a conical apex, glabrous, with a
