Annual Report.] 316 [May 4, 



brates, 536 of travels and local faunae, and Journals and pub- 

 lications of Societies number 4,173. No classification of the 

 pamphlets can be given until they are in a more orderly con- 

 dition. 



707 books have been borrowed from the library by 85 

 persons ; none are supposed to have been lost. 



The exploration on the Isthmus of Tehuantepec, on the 

 part of Prof. F. Sumichrast, referred to in the preceding Re- 

 port, has been continued during the past year, and several 

 boxes of specimens have been forwarded to Washington. 



In accordance with the arrangement made with the Smith- 

 sonian Institution, all the insects have been sent to us for 

 arrangement and identification, the other collections being 

 distributed to specialists, for a like purpose. The birds are 

 in the hands of Mr. George N. Lawrence of New York, by 

 whom a list will be prepared on the completion of the entire 

 labor, and presented to the Society for publication. The rep- 

 tiles, in a similar manner, have been placed in the hands of 

 Prof. E. D. Cope, and the land shells in the care of Mr. 

 Thomas Bland of New York. It is believed, in view of 

 the eminence of Prof. Sumichrast as a naturalist, and his 

 well-known ability as a collector, that important results to 

 science will be developed by a careful examination of his 

 collection. The expenses of this exploration, in addition to 

 the contribution on the part of the Society, have been borne 

 mainly by the Smithsonian Institution and the Kentucky 

 University at Lexington, aided by a moderate contribution 

 from the Academy of Natural Sciences at Philadelphia. 

 Such portion of the expense as has not been met by sub- 

 scriptions already named, will, it is hoped, be defrayed by 

 the sale of duplicate specimens. . 



It is with great regret that we announce the death of our 

 esteemed coadjutor, Col. A. J. Grayson, to whose labors, 

 in the exploration of north-western Mexico, the Society has 

 contributed in connection with the Smithsonian Institution.
