24 PALUDINA BENGALENSIS. 



OBSERVATIONS. 



This species is most nearly allied to P. 

 decisa, Say; from which it may be distinguish- 

 ed by the subrotund aperture; and from P. vivi- 

 para, by the want of the rufous bands. That 

 it is a distinct species, I have not the least 

 doubt. I am indebted to Mr. Lea for the use of 

 his original specimen to figure and describe.
