PALUDOMUS. 
Puare II. 
Species 12. (Hig. a, 6, c, Mus. Cuming.) 
Patupomus Tennant. Pail. testd obovatd, crassiusculd, 
spira vie easertd ; anfractibus rotundatis, levibus aut 
obscurissimé liratis; aperturd subampliter effusd ; 
olivaced, fusco indistincte longitudinaliter undata, intus 
albidé, columellé et aperture limbo purpureo-fusco 
tinctis. 
Tpnnant’s Patupomus. Shell obovate, rather thick, 
spire scarcely exserted ; whorls rounded, smooth, or 
very obscurely ridged ; aperture rather largely effused ; 
olive, indistinctly longitudinally waved, interior white, 
columella and edge of the aperture stained with 
purple-brown. 
Hab. Tn a rocky stream flowing from Adam’s Peak, Cey- 
lon; Gardner. 
An equally interesting species with the P. Gardneri, 
distinguished in early growth by an elaborate pattern of 
waved painting, which is very conspicuous in the interior 
of the shell. At a more advanced period, this striking 
display of pattern is entirely obscured by a superincum- 
bent deposit of colourless matter. 
By the title given to this species I wish to honour the 
name of Sir Emerson Tennant of Ceylon, whose zeal in 
this department of Natural History may serve to promote 
the discovery of other genera, which, like the present, are 
almost indigenous to that country. 
Species 13. (Mus. Cuming.) 
PaLupomus FunicuLatus. Pal. testi oblongo-ovati, 
spira exsertd, anfractibus superné depressiusculis, liris 
subdistantibus obtusis spiraliter funiculatis ; nigerrimo- 
Suscd, intus albidd. 
THE corDED Patupomus. Shell oblong-ovate, spire 
exserted, whorls rather depressed round the upper 
part, spirally corded with rather distant obtuse 
ridges ; jet brown, interior whitish. 
Hab. Tn a mountain stream at Ratnapoora, Ceylon; 
Gardner. 
Of a dark sombre colow, without any indication of 
pattern, encircled throughout with rather distant ridges. 
Species 14. (Pl. IL. Fig. a and 4, Pl. III. Fig. c. 
Mus. Cuming.) 
Patupomus conicus. Pal. testa subglobosd, spird ea- 
sertd, anfractibus rotundatis, levibus nisi ad basin et 
per suturas indistincté sulcatis ; apertura mediocrt, 
labro subobscuré denticulato; castaneo-fuscd, imtus 
albidd. 
THE conicaL Patupomus. Shell somewhat globose, 
spire exserted, whorls rounded, smooth unless indis- 
tinctly grooved towards the base and along the 
sutures ; aperture moderate, lip somewhat obscurely 
denticulated ; chesnut brown, interior whitish. 
Melania conica, Gray in Griffith’s Cuvier, pl. 14. f. 5. 
Hab. Himalaya, India; Benson, Dr. Cantor. 
A rounded shell, with the spire more or less exserted, 
and perfectly smooth, excepting along the sutures and 
towards the base where there are faint superficial grooves, 
causing the lip to be slightly denticulated. 
This is one of the species referred to by Mr. Swainson 
for the illustration of his genus, but we are now acquainted 
with several, P. loricata, Gardneri, Tennantii, and Ne- 
ritoides, for example, more typical of the character upon 
which he founded it. 
Species 15. (Mus. Cuming.) 
PaLupomus sprratis. Pal. testd ovati, spird ampli, 
prominuld, anfractibus rotundatis, levibus ; olivaced, 
nigro hic illic maculata, intus alba. 
THE SPIRAL Patupomus. Shell ovate, spire large, pro- 
minent, whorls rounded, smooth; olive, spotted here 
and there with black, interior white. 
Hab. Streams of Ceylon; Dr. Sibbald. 
This little species, which is quite on the confines of the 
genus passing into Melania, was brought from Ceylon 
some years since by Dr. Sibbald. 
July, 1847.
