I have not attempted to give in connection with this paper a com- 

 plete bibhography of the subject, as such an undertaking seems un- 

 necessary in the case of any student who has access to the works men- 

 tioned above and to the 'Zoological Record.' A complete bibliography 

 would constitute a considerable volume in itself. 



Before closing these brief introductory notes I desire to express my 

 sincere gratitude to Dr. F. E. Lutz and his amiable associates in the 

 Department of Invertebrate Zoology in The American Museum of 

 Natural History, and to the Director of the Museum, Dr. F. A. Lucas, 

 who kindly granted me the pi-ivilege of reserving for our collections in 

 Pittsburgh a small series of duplicates of each species in cases where 

 there were duplicate specimens in sufficient number to permit the writer 

 to retain a few. For this generous permission, as well as for the uni- 

 formly kind indulgence shown me by the officials of The American Mu- 

 seum of Natural History, I desire to express my thanks. To Mr. 

 Herbert Lang, the leader of the expedition, I am indebted for a number 

 of kind letters written to me in answer to inquiries made during the 

 progress of my work.
