PALUDIN A 



Plate IX. 



Species 4'9. (Mus. Cuming.) 



Paludixa Thermites. Pal. testa, globosd, fuho-olivacea, 

 spird brevi, subimmersd, siitiiris canaliculatis, anfrac- 

 tibus supertie obtuse multicarinaiis ; aperiurd parvius- 

 culd. 



The Theesites Paltjdina. Shell globose, fulvous- 

 olive, spii'e sbort, somewhat immersed, sutures chan- 

 nelled, whorls obtusely many-keeled round the upper 

 part ; aperture rather small. 



Hanley, MS. in Mus. Cuming. 



Hai. ? 



The spire is in this species curiously immersed, but it is 

 not a deformity of growth. There is another equally cha- 

 racteristic specimen in the British Museum. 



Species 50. (Pig. a, b, Mus. Ciuning.) 



Paltjdina lineolata. Pal. testa ovato-conicci,virescenie, 

 nigricante-oUvaceo midtilineatd, anfractibus lavibiis, 

 superne declivibus, deinde convexis ; aperturd parvius- 

 ciild, pyriformi-rotundatd. 



The lineated Paludina. Shell ovately conical, green- 

 ish, many-lineated with dark-olive, whorls smooth, 

 sloping round the upper part, then convex ; apertiu'e 

 rather small, pyriformly rounded. 



MoDSSON, MS. in Mus. Cuming. 



Hab. Siam. 



A smooth linearly-painted shell, of the same type as 

 P. Bengalemis, uniformly smaller and of a more slopiugly 

 conical form. 



Species 51. (Mus. Cuming.) 



Paludina fallax. Pal. testd ovato-couicd, subinfiatd, 

 virescente-oUvaced, anfractibus superne sabangulatis, 

 obscurissime carinatis et malleatls, undupie minute 

 grano-striatis ; aperturd pyriformi-ovatd. 



The deceptive Paludina. Shell ovately conical, rather 

 inflated, greenish-olive, whorls faintly angled round 

 the upper part, very obscurely keeled and malleated, 

 everywhere minutely grain-striated ; aperture pyri- 

 formly ovate. 



Vivipara fallax, Frauenfeld, Ueber die Gattung Fivipara, 

 November, 1S62. 



Hab. Brazils? Madras? 



Having compared this shell in Mr. Cuming's collection 

 wdth Prauenfeld's original type of P. fallax, I can affirm, 

 without any doubt, that they are the same. The habitat 

 "Brazils," which Mjc. Cuming has with it, may be erro- 

 neous. Frauenfeld gives Madras. 



Species 53. (Mus. Cuming.) 



Paludina Javanica. Pal. testd ovato-conicd, solidius- 

 culd, nigricante-olivaced, anfractibus convexis, obscu- 

 rissime carinatis, undique valide lineari-striatis, lou- 

 gitudinaliter plicato-slriatis, anfractu ultimo circa 

 umbilicum aiigulato-excavato ; aperturd pyriformi- 

 ovatd. 



The Java Paludina. Shell ovately conical, rather solid, 

 dark-olive, whorls convex, very obscurely keeled, 

 strongly linearly striated throughout, plicately stri- 

 ated longitudinally, last whorl angvdarly excavated 

 around the umbilicus ; aperture pyriformly ovate. 



Von dem Buscii, Albild. und Besch. Conch, pi. 1. 

 f. 11, 13. 



Hab. Java. 



In this species the gi'anular strise assume the form of 

 linear ridges, and longitudinal strise descend in a plicated 

 manner from the sutures. 



Species 53. (Mus. Cuming.) 



Paludina cakinata. Pal. testd subgloboso-conicu, fnlcd, 

 obscurissime fasciatd, aifraclibus rotundatis, prima ad 

 viarginem inferiorem carinatis, deinde striis undulatts 

 sericeis undique confertim decnssatis ; aperturd ovatd. 



The keeled Paludina. Shell somewhat globosely 

 conical, fulvous, very faintly banded, whorls rounded, 

 at first keeled at the lower margin, then very closely 

 decussated throughout with waved silken striae ; aper- 

 ture ovate. 



Hub. Philippine Islands. 



Of a peculiar fulvous colour, keeled round the lower 

 edge of all but the last whorl, in which the keel fades 

 away.
