PUBLICATIONS OF THE MUSEUM. 



For the convenience of scientific workers it has been deemed 

 expedient to issue the publications of the Museum in separate series 

 for each of the sciences represented. The following series have been 

 established : Historical, Geological, Botanical, Zoological, Ornitho- 

 logical and Anthropological. 



A consecutive number has been given tbe entire set of pub- 

 lications to indicate the order of issue. Each departmental series, 

 however, has its own volume number and individual consecutive 

 pagination, making the literature of the science, or general subject, 

 independent and complete for separate binding: or they may be 

 bound in order of publication without relation to subject. Proceed- 

 ings, memoirs, monographs, bulletins, and hand-books and catalogues 

 of collections, are included within the scope of the publications. 



Full lists of the publications of the Museum may be found in the 

 Annual Report of the Director. 



Publications are sent to societies and institutions of a public 

 character that reciprocate with their own literature, and to a limited 

 number of scientists who are able to exchange. 



Two publications have been previously issued in the Zoological 

 Series: Hay, "On the Structure and Development of the Vertebral 

 Column of Amia," (Pub. 5), and Hay. "On certain portions of the 

 Skeleton of Protestega gigai," (Pub. 7).
