been published : Xo. 1087, "Preliminary description of a new genus and 

 two new species of Crustaceans from an artesian well at San Marcos,

 Edgar A. Mearns. Manuscripts of fourteen additional papers to be 

 published in the Proceedings were in the hands of the printer at the 

 close of the fiscal year, and nineteen more have been accepted for 

 publication. 



The following additional parts of Bulletin 39 have been issued : Part 

 H, "Directions for collecting minerals," by Wirt Tassin; Part I, "Direc- 

 tions for collecting rocks and for the preparation of thin sections," by 

 George P. Merrill; Part J, "Directions for collecting specimens and 

 information illustrating the aboriginal uses of plants," by Frederick V. 

 Coville; Part K, "Directions for collecting and preparing fossils," by 

 Charles Schuchert. 



Circular 47, in regard to the identification of mollusks by the National 

 Museum, has been issued. 



The titles of all the papers which have appeared in the form of sepa- 

 rates during the year are given in Appendix v. 



Bulletin No. 47, " The Fishes of North and Middle America : A Descrip- 

 tive Catalogue of the Species of Fish-like Vertebrates found in the 

 Waters of North America North of the Isthmus of Panama," by David 

 Starr Jordan and Barton Warren Evermann, a volume of 1,1^40 pages, 

 is entirely in type and will be shortly put to press. The present Bul- 

 letin constitutes Part 1 of the work. A second volume of text and an 

 atlas of plates will be published later. 



Bulletin No. 49, "A Bibliography of the Published Writings ot Philip 

 Lutley Sclater, F. R. S., Secretary of the Zoological Society of London," 

 prepared under the direction of Dr. G. Brown Goode, has been set in 

 type. It contains 135 pages, with a portrait of Dr. Sclater as a frontis- 

 piece. Much care has been given to the typography, with a special view 

 to securing compactness and clearness. This work is not included in 

 the series of Bibliographies of American Naturalists, of which five have 

 been published (Bulletins 20, 23, 30, 40, and 41), since the scope of this 

 series is necessarily limited to the work of naturalists living in the 

 United States; but, inasmuch as Dr. Sclater's contributions to the 

 systematic ornithology of the American continent have exceeded in 

 extent those of anyone living in this country, it was deemed proper 

 that the XJ. S. National Museuni should publish his bibliography. 



It was hoped that the second and third numbers of the Special Bul- 

 letin, the first of which appeared in 1892, would be ready for distribu-

 this was impossible. No. 2 of the series, entitled "Oceanic Ichthyol- 

 ogy : A Treatise on the Deep-sea and Pelagic Fishes of the World, based
