The publications of The American Museum of Natural 

 History for the current year are composed of the Annual 

 Report; the Bulletin; the Anthropological Papers; 

 Natural History, Journal of The American 

 Museum of Natural History; the Guide Leaflet, and the Hand- 

 book. 



The Annual Report gives each year a short review of the 

 administrative and educational activities of the institution. 

 It is particularly pertinent to all who are interested in the 

 welfare and progress of the Museum as well as to those who 

 for practical purposes are concerned with museum organiza- 

 tion. 



The Bulletin is the organ whereby the scientific staff publish 

 the results of the field and laboratory work for the year. It 

 consists of twenty to twenty-five articles issued more or less 

 regularly throughout the year and at the conclusion bound 

 into a volume. During 1919 Volume XLI was published, which 

 contains three articles on Mammalogy, one on Ichthyology, nine 

 on Invertebrate Zoology, three on Vertebrate Palaeontology, 

 two on Herpetology, one on Ornithology and one on In- 

 vertebrate Palaeontology. Also two volumes relating to the 

 Belgian Congo were published : Volume XXXIX, containing 

 a monograph by Bequaert on "A Revision of the Vespidae 

 of the Belgian Congo Based on the Collection of The American 

 Museum Congo Expedition, with a List of Ethiopian 

 Diplopterous Wasps," and a monograph by Schmidt on "Con- 

 tributions to the Herpetology of the Belgian Congo Based on 

 the Collection of The American Museum Congo Expedition, 

 1909-1915"; and volume XL which is devoted entirely to 

 Pilsbry's paper on "A Review of the Land Mollusks of the 

 Belgian Congo Based on the Collection of The American 

 Museum Congo Expedition, 1909-1915." The collection of 

 papers on the Belgian Congo has steadily increased. A List 

 cf Reports on the Results of The American Museum Congo 

 Expedition published this year contains a short description 

 of fifteen such papers. These reports, two volumes, bound 

 in red morocco, with illuminated frontispiece, were presented 

 to the King of Belgium on his recent visit to the institution.
