PRELIMINARY NOTE. 



The succeeding Catalogues include all the species of which speci- 

 mens are in the Collection, with the localities given, as determined 

 by the naturalists of the Expedition, and generally stated by them 

 in labels attached during the voyage. In some instances, however, it 

 is quite impossible to give the exact locality, specimens having been 

 obtained from naturalists, or from dealers or other persons, at places 

 evidently not the habitat of the species. In such cases I have in- 

 closed the locality in parentheses.
