SPECIES OF DRAPARNaUD ; AND ERRATA. 



After the foregoing part of this volume had been 

 printed^ I received a communication of considerable im- 

 portance as regards the determination of some of the 

 species described by Draparnaud. It consisted of the 

 original types or specimens of that author, from the 

 public museum at Montpellier, and which, through the 

 great kindness of the Director, M. Michaud, I have now 

 had an opportunity of examining and comparing with 

 my own specimens. The following is the result of this 

 examination.
