The Coosa Paludina. Shell subglobose, dusty-olive,

 Vivipara Coosaensis, Binney.

Distinguished by an impressly channelled suture, and 

 a peculiar sculpture of longitudinal crisply wrinkled 

 striae.

 Vivipara TFareana, Binney. 



Hab. Lake Ware, East Florida, United States. 



According to the specimen preserved in !Mr. Cuming's 

 collection as a type of this species, it is a shell of rather 

 solid growth, densely constrictedly striated throughout, but 

 yet thin and transparent towards the aperture. 



Species 24. (Mus. Cuming.) 



Paludina Texana. Pal. tesid snbpyramidali-conlcd, 

 solidd, virescente, suturis impressis, anfractibus plano- 

 declivibiis, medio snbcoiicavis, ad basin rotundatis ; 

 aperturd piriform i-circulari, parviiisculd. 



The Texas Paludina. Shell somewhat pyramidally 

 conical, solid, light green, sutures impressed, whorls 

 flatly sloping, slightly concave in the middle, rounded 



at the base ; aperture pyriforinly circular, rather 



small. 

 Vivipara Texana, Tryon, Pro. Acad. Nat. Sci. Phil. 1863. 



Vivipara subpurpurea, var., Binney. 

 Ilab. Texas, United States. 



This species has been lately described by Mr. Tryon. 

 Mr. Binney considers it a variety of P. subpurpurea ; but 

 if the specimen here figured can be relied upon as a type, 

 and I know not to what other species it can be referred, 

 P. Texana should, I think, be retained. 



Species 35. (Fig. a, b, Mus. Cuming.) 



Paludina malleata. Pal. testd globoso-conicd, sub- 

 inflatd, vivide olivaced, anfractibus rotundatis, longi- 

 tudinaliter copiose plicato-striatis, spiraliter obscure 

 lineari-puncturatis, ubique malleatis ; aperturd pyri- 

 formi-ovatd, labro nigro-marginaio. 



The malleated Paludina. Shell globosely conical, 

 rather inflated, bright olive, whorls rounded, longi- 

 tudinally copiously plicately striated, spirally ob- 

 scurely linearly punctured, everywhere malleated ; 

 aperture pyriformly ovate, lip black-edged. 



Ilab. Japan. 



This and the following Japanese species difl'er from the 

 American species of similar form, P. intertexta for example, 

 in beino; malleated throuirhout. 



Species 36. (Fig. a, h, Mus. Cuming.) 



Paludina abbkeviata. Pal. testa globosd, nigricante- 

 olivaced, spird abbreviatd, anfractibus rotundatis, ad 

 suturas oppressis, inferne obsolete angulatis, longiiudi- 

 naliter copiose constricio-striatis, spiraliter obscure 

 lineari-puncturatis, ubique malleatis ; aperturd pyri- 

 formi-ovutd, labro nigro-niarginaio. 



The shortened Paludina. Shell globose, dark olive, 

 spire shortened, whorls rounded, appressed at the 

 sutures, obsoletely angled round the lower part, 

 longitudinally copiously constrictedly striated, spi- 

 rally obscurely linearly punctured, everywhere mal- 

 leated ; aperture pyriformly ovate, lip black-edged. 



Hab. Japan.
