A very distinct minutely punctured species, of rather 

 solid growth, encircled very irregularly with purple bands, 

 some of which are quite linear.

The thread-encircled Paludina. Shell ovately co-

Hab. ? 



Another veiy characteristic species, with a shining vel- 

 lowish-olive surface neatlv nded with black linear bands. 



Species 32. (Mus. Cuming.) 



Paludina Ceylanica. Pal. te.itd ovnio-conicd, solidius- 

 culd, virescente-olivaced, anfractibus plano-coiwe.vis, 

 superne et inferne decliti-angulatis, ubique dense spi- 

 raliter lineari-striatis et puncturatis, ad angulos ob- 

 tuse carinatis ; aperturd pyriformi-ovatd, nigro-mar- 

 ginatd. 



The Ceylon Paludina. Shell ovately conical, rather 

 solid, greenish-olive, whorls tlativ convex, flatlv anded 



above and below, everywhere closely spirally linearU 

 striated and punctured, obtusely keeled at the aiigles 

 aperture pyriformly ovate, black-edged. 



DoHRN, Pro. Zool. Soc. 1857, p. 123. 



Hab. Ceylon. 



Readily recognized by its obtusely-angled form and 

 dense sculpture of spiral lines and punctures. 



Species 33. (Pig. a, b, ]\Ins. Cuming.) 



Paludina crassa. Pal. testd orato-turbinatd, solidd, 

 Jlacescente-olivaced, anfractibus rotundatis, ad -mturas 

 constrictis, oblique plicato-striatis, spiraliter minutis- 

 sime nndato-striatis et puncturatis ; aperturd fere cir- 

 cularl, nigro-marginatd. 



The thick Paludina. Shell ovately turbinated, solid, 

 yellowish-olive, whorls rounded, constricted at tlit- 

 sutures, obliquely plicately striated, spirally very mi- 

 nutely wave-striated and punctured ; aperture nearly 

 circular, black-edged.

 Paludina obtusa, Troschel. 



Hab. Jaunpore, India ; Burmah. 



Of a peculiarly solid constricted growth, copiouslv mi- 

 nutely punctured, like most Eastern species. 



Species 34. (Mus. Cuming.) 



Paludina zonata. Pal. testd nnguste subprofundi uni- 

 bilicatd, ovato-coni.cd, viride vii-ente-olivaced, nileute.

 leevibus, sub lente minute pzuicturatis ; aperturd pyri- 

 fonni-circulari, nigro-margiuatd. 



The zoned Paludina. Shell narrowly rather deeply 

 umbilieated, ovately conical, bright greenish-olive, 

 shining, encircled with neat black linear bands, whorls 

 convex, smooth, beneatii the lens minutely punctured ; 

 aperture ])yriformly circular, black-edged.
