PALUDOMUS. 
Puate II. 
Species 6. (Mus. Cuming.) 
PaLUDOMUS NIGRICANS. Pal. testi ovatd, spird promi- 
nuld eusertd, anfractibus levibus, basin versus subin- 
distincté angulatis; nigricante, intus c@rulescente- 
alba. 
THE BLACKISH PaLupomus. Shell ovate, spire rather 
prominent, exserted, whorls smooth, faintly angled 
towards the base; blackish, interior blueish white. 
Hab. Ceylon (in mountain streams at 6,000 feet eleva- 
tion); Gardner. 
This little species partakes a great deal of the character 
of Melania, being about intermediate between the genera. 
Species 7. (Fig. a and PI. III. Fig. 7. 4, c. Mus. Cuming.) 
Patupomus CuHILinomEs. Pal. testd ovata, tenuiculd, 
spird parva, exserté, anfractibus superné depressis, 
levibus ; olivaced, nigro longitudinaliter undata. 
Tue CHILINA-LIKE Paxtupomus. Shell ovate, rather 
thin, spire small, exserted, whorls depressed round 
the upper part, smooth; olive, longitudinally waved 
with black, aperture white. 
Hab. Bed of the Mahawelle Ganga, near Kandy, Ceylon ; 
Gardner. 
Found abundantly in the stream above noted; the 
chief variation of form consists in the whorls being more 
or less depressed round the upper part, after the manner 
of a Chilina, with the spire varying considerably in its 
elevation, 
Species 8. (Fig. a and PI.IIT. Fig. 8 4, c. Mus. Cuming.) 
PaLupomus sutcatus. Pal. testé ovatd, spird prominuléd, 
anfractibus rotundatis, spiraliter creberrimé sulcatis, 
suleis lirisque intermediis striis longitudinalibus ere- 
berrimé decussatis ; luteo-olivaced, nigricante hic illic 
picti, interdum tota nigra, intus albida. 
THE GROOVED Patupomus. Shell ovate, spire prominent, 
whorls rounded, spirally very closely grooved, grooves 
and intermediate ridges very closely decussated with 
longitudinal striz ; yellowish olive, painted here and 
there with black, sometimes entirely black, interior 
whitish. 
Hab. In a mountain stream at Ratnapoora, Ceylon; 
Gardner. 
A neatly grooved species of a light yellow olive with a 
few black waved spots, as represented in PI. III. Fig. 8, 
6, c, or entirely black as at Fig. 8 a. 
Species 9. (Fig. a, 6, Mus. Cuming.) 
Patupomus Garpnurit. Pal. testé orbiculari-ovatd, 
spird plano-depressd, anfractibus requlariter convents, 
creberrimé spiraliter liratis, liris tenuiusculis, obtusis, 
alternatim majoribus ; aperturé perampla ; aterrimd, 
intus albidé, columellé et aperture limbo purpureo- 
nigro tinctis. 
GARDNER’s PaLupomus. Shell orbicularly ovate, spire 
flatly depressed, whorls regularly convex, very closely 
spirally ridged, ridges rather thin, obtuse, alternately 
larger ; aperture very large ; jet black, interior whitish, 
columella and margin of the aperture stained with 
purple-black. 
Hab. Tn a stream at the foot of Adam’s Peak, Ceylon ; 
Gardner. 
The most characteristic species of the genus and farthest 
removed from the Melania type; I therefore name it in 
honour of its discoverer, George Gardner, Esq., a gentle- 
man well known to botanists and horticulturists by his 
productive researches in the great Orchid country of 
Brazil, and to the public in general by the interesting narra- 
tive of his ‘ Travels’. 
Species 10, (Fig. a, 0. Mus. Cuming.) 
Patupomus pictus. Pal. testé oblongo-ovatd, spiré ex- 
sertd, anfractibus spiraliter obtuse striatis ; olivaced, 
fasciis nigris undulatis angustis longitudinaliter picta, 
intus albidd, columelle margine fusco tincto. 
THE PAINTED Patupomus. Shell oblong ovate, spire 
exserted, whorls spirally obtusely striated; olive, 
painted longitudinally with narrow undulated waved 
bands, interior white, margin of the columella stained 
with brown. 
Hab. To a mountain stream at Ratnapoora, Ceylon; 
Gardner. 
The waved painting may be observed in adult specimens 
on the outside, when not visible in the interior, 
July, 1847.
