364 PKOCEEDINGS OF THE MALACOLOGICAL SOCIETY. 



While in Paris I also visited the rich collection of Mr. Dautzen- 

 berg, and found there material confirming my previously expressed 

 opinions on several species with which my acquaintance was limited. 

 Mr. Dautzenberg has a specimen of A. Tamsiana, Phil., much larger 

 than any I have previously seen; it measures 47x46 mm. The 

 specimens of African species in Mr. Dautzenberg's collection I found 

 helpful and instructive, but of these I will treat in my next paper.
