Mr. S. Hanley on a new Indian Clausilia. 343, 
Fig. 2. Ellipsoidina ellipsoides, elongate form, originally described as E.. 
oblonga. 
Fig. 3. The same, subglobular variety, at first described as FE. abbreviata. 
Fig. 4. Same specimen as fig. 1, but with the two outer chambers partially 
broken away so as to show the internal structure; x 25 diam. 
Fig. 5. Inner chamber of another shell, showing the central column 
(usually more or less tubular) tri-cleft and spreading. 
Fig. 6, Part of a central column dividing near its summit into smaller 
members, with the portion of the shell-wall immediately above 
it still adhering. | 
Figs. 7-10 are intended to illustrate the form of the external and septal 
apertures. Fig. 8 is an end view of a specimen without a neck, 
but otherwise perfect, showing what seems to be the ordinary 
condition of the external orifice. Fig. 7 is a representation of a 
similar shell broken down the centre. Figs. 9 & 10 relate tu 
the inner chambers. 
Fig. 11. Abnormally formed primordial chambers of an elongate specimen. 
Fig. 12. Multicellular nucleus found in the primordial chamber of a large 
: example, x 180 diam. 
XLIIU.—Deseription of a rare Indian Clausilia. 
By Sytvanus HAN ey, Esq., F.L.S. 
Clausilia tuba, Hanley. 
Testa (pro genere) magna, subcylindraceo-fusiformis, apicem 
- obtusum versus cylindracea, albido-cornea, unicolor, tenuis, 
subdiaphana, haud rimata, lineis elevatis vix continuis 
et (presertim in anfractu ultimo, ubi remotiores fiunt) 
oblique corrugata. Anfractus 10-12, sutura profunda et 
minime crenata divisi; apicales unice convexi, subsequales ; 
exeteri convexi, et satis rapide crescentes.; penultimus major, 
altior; ultimus curvatus, verticaliter descendens, infra su- 
turam submarginatam subcoarctatus, denique insigniter di- 
latatus, basi rotundata nequaquam cristatus. Apertura 
permagna, soluta, porrecta, subcordato-rotundata, undique 
_ patentissima. ‘Peristoma .continuum, late expansum: la- 
mella supera conspicua, angusta, arcuatim subverticalis ; 
lamella infera adjacens, obliqua, magisque profunda; plica 
subcolumellaris parvula, verticalis; plica palatalis (si sit 
ulla) labrum haud attingens: lunella opacitate conspicua. 
Long. 1} poll. 
Hab. Shan, province. Ind. or. Mus. Theobald, Hanley. 
I am indebted to W. Theobald, Esq., for this remarkable 
species, which must aus resemble the American C. episto- 
mium. It was taken by Mr. Fedden from the valley of the 
Upper Salwen.
