In concluding, I have to thank the Hon. Walter Rothschild and Dr. E. Hartert 

 for entrusting me with the study of the interesting material and for publishing tlie 

 report thereon in this periodical. I am also under great obligations to my kind 

 friend Dr. von Lorenz, of Vienna, who lent me numerous specimens from Natterer's 

 collection, and to Count Berlepsch for similar favours and valuable advice in difficult 

 questions.
