PALUDINID-ffil. 27 



var. sphsericula. 



Piilndiiia sphsericula, Deshayes, I. c, Cambodia. 



2 Cochin-china j ex c. P. Bouvier, Esq. 



These are, I think, the form called P. splicericnla ; unfortu- 

 nately they are not quite adult ! They present the sharp angu- 

 lation of the columellar margin at base, said to be characteristic 

 of P. rattrei ; may this not arise from the form not being adult ? 

 Long. 24J, diam. 20| mil. 



25. Paludina lurida. 



Paludina lurida, Morelet, Rev. Zool. 1862, Saigon : long. 21%, diam. 17 mil. 

 1 Cochin-China; ex c. A. Morelet, Esq. 



Very close to typical P. crassa ; it also much resembles the 

 Tenasserim specimen of P. siamensis^ var. burmanica, but is 

 larger, with more exserted spire and less obtuse apex.

1 Sagar; ex Mr. Sowerby [ex c, Lombe Taylor], 



This last a magnificent specimen — long. 2 7 J, diam. 21 mil. — 

 scarcely angulate at the periphery, with the white belt sub- 

 obsolete, was labelled " P. oUvacea." 



subvar. SUbobtusa, nov. 



3 Chdndballi; coll. G. Nevill, Esq. 



The whorls have not the peculiar, convex sha^DO of var. ohtusa. 

 It is probably the P. vielano stoma of Benson, Ms., but not of 

 Reeve! I described it without a name Cat. Moll. Fasc. B., 

 p. 38 : long. 2Q^, diam. 21 mil. : decollate, 3 whorls only 

 remaining.
