 Mason University College, Birmingham. 



[Plates Vir. & VIIL] 



The species here described form part of a collection of mollusks 

 which has been placed in my hands for investigation by the 

 Council of the Birmingham Natural History and Philosophical 

 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.

The anatomy of this species has been treated of by 

 Semper (2) and Simroth (3). In the pi^esent collection there 

 are a large series of specimens, many of which I have dissec ed. 



The generative organs are well hgured by feimroth (3), 

 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 tlie
