South-African Land-Mollusca.

spermatheca was very large and swollen at the free end. 

 This appearance indicated a spermatophore (PI. XX. fig. 2 a) 

 "vvas within it, and with great care I managed to extract it 

 nearly complete. The spines, however, were all broken off 

 except one ; there were only fifteen, less than in others I have 

 seen, all on one side (j.). This, and its shorter flume, is a 

 good specific character. The single spine entire is simple, 

 biiid.
