XLVII. — Oil some Land- Mollusks from Java^ with Descrip-

[Plates VIL & VIII.] 



The species here described form part of a collection of mollu.^ka 

 which has been placed in my hands for investigation by the 

 Council of the Birmingham Natural History and Piiilosophical 

 Society, and I take this opportunity of expressing my thanks 

 to them for so interesting a collection and for their further 

 kindness in defraying the cost of the drawings. 



The collection includes two well-known and one doubtful 

 species of Parmarion and two species of Microparmarion, one 

 of which is new. 



Parmarion. 

 1. Parmarion pupillaris, Humb. (PI. Vll. figs. 1, 2.) 



Hob. Geda. 



The anatomy of this species has been treated of by 

 Semper (2) and Simroth (3). In the present collection there 

 are a large series of specimens, many of which I iiave dissected. 



The generative organs are well figured by Simroth (8), 

 and those dissected by me agree in all particulars ; in two 

 cases, however, an interesting and important variation was 

 found in the form of the receptaculum seminis. In the
