Paludina martensiana, n. sp. 



Imperforate, spire more or less shortly produced, moderately thick, of 

 greenish brown colouration, suture rather indistinct, apex obtuse ; whorls 

 3 to 4, planulately turreted (almost concavely), the last whorl about twice 

 the size of the others, rounded at base, with one acute and raised spiral 

 keel immediately below the suture and three or four others crowded to- 

 gether at the periphery, the preceding whorl has two of these prominent 

 keels and both have besides, under the lens, a very minute, subobsolete, 

 spiral striation ; aperture oval, relatively rather small, not oblique, peris- 

 tome scarcely thickened, but slightly convex, having a very slight suban- 

 gulate appearance about the middle, coluinellar margin a little reflected, 

 evenly rounded.

I have thought it advisable to give a figure of this very distinct, 

 imperforate species, for which the Museum is indebted to Dr. J. Anderson, 

 although there is no species which I know of with which it could possibly 

 be confused. 



Btthinea philippinensis, n. sp. 

 Somewhat closely resembling B. lutea, Gray = B. goniostoma,Hwiioxi ; 

 slightly decollate, distinctly umbilicate, spire variable, sometimes very short,

 ately solid, suture distinct, whorls 3 to 4, convex, the last one globosely 

 and tumidly swollen, rounded at the perij)hery, more or less angulate round 

 the deep, open umbilicus ; under the lens spirally, very closely striated,
