14: MUSEUM OF COMPARATIVE ZO-OLOGY. [Jan. 



tions in our behalf, and Dr. Walsh has sent us series of his 

 original specimens. 



Notwithstanding the general interest felt in the Museum, and 

 the numerous additions we have received from private individ- 

 uals, by far the largest additions to our stores have been 

 received as exchanges. These have been continued on the most 

 satisfactory footing with the Jardin des Plantes through Profes- 

 sors Milne Edwards and Dumeril, to whom we have continued 

 to send, during the past year, living specimens of our common 

 North American animals. In this I have been greatly assisted 

 by the zeal of Mr. J. G. Rich, of Maine. I have to thank, also, 

 Mr. B. P. Mann, of Concord, and Mr. S. Jillson, of Felton- 

 ville, for the many living specimens they have furnished the 

 Museum, as well as Mr. H. K. Moore and Mr. 0. St. John. From 

 the University Museum, of Copenhague, through Professor 

 Steenstrup, we have a valuable invoice of cetacean skeletons. 

 From the Museum of Gottingen, through Professor Keferstein, 

 reptiles from Australia. Messrs. E. L. Layard and W. Theobald 

 have sent us valuable exchanges. Through Professors Gegen- 

 baur and Haeckel we have obtained a collection of marine 

 animals from the Mediterranean, German Ocean, and fishes 

 from the Danube and Rhine. We have received Italian fossils 

 for our duplicates from Professor Gastaldi, Messrs. Michelotti and 

 Rigacci. Professor Poey has continued to send us Cuban fishes. 

 Professors Krauss, Merian, Angelin, and Mr. Pickett, have 

 sent us valuable exchanges of fossils. To the Chicago Academy, 

 of Natural Sciences we owe an important collection of Northern 

 and Western birds. Mr. Henry Edwards has continued his 

 valuable invoices. Dr. Kaup has sent us an extensive collec- 

 tion of insects in exchange for American species. Besides 

 these more general exchanges, I have to mention those of the 

 special departments with Don Rafael Arango, C. F. Angas, I. A. 

 Lapham, Robert Swift, G. W. Tryon, M. Tervers, Prof. Oppel," 

 Dr. Newcomb, Barrande, and other minor exchanges, amount- 

 ing, as will be seen by the special reports, to extensive additions. 



Among the other additions, I must notice specially a very 

 important collection made at Lake Titicaca and on the coast of 

 Peru by Mr. E. G. Squier ; the collections of Nova Scotia fos- 

 sils by Mr. Hartt, and of Dr. Stimpson on the coast of New 

 Jersey ; of Mr. J. M. Nelson in the interior of Newfoundland,
