8 ANNUAL REPORT OF THE 



Several North American mammals have been added to the 

 collection on exhibition, as a result of Dr. H. B. Bigelow's zeal 

 and Mr. Nelson's skilful taxidermy. A number of heads and 

 horns of some typical forms of hoofed Mammalia have been 

 mounted by Mr. Nelson and are hung on the walls of the entrance 

 Hallway. 



Through the kind interest of Professors J. B. Woodworth and 

 C. H. Hitchcock the Museum has obtained a large slab of Potsdam 

 sandstone, showing the tracks of the enigmatical animal known as 

 Climatichnites wUsoni. The slab is from Mooers, N. Y., and is 

 installed in the entrance Hallway. 



New cases have been built in the Hallway, in the Pacific Room, 

 in the Coral Room, and in the rooms devoted to the Systematic 

 collections of mammals and of fishes. 



A rearrangement of the Systematic collection of fishes on exhibi- 

 tion has been begun; for the Synoptic collection of fishes the 

 rearrangement is completed. The arrangement of the collections 

 in the room devoted to the Pacific Fauna has been changed; the 

 vertebrates are displayed in the wall cases, the invertebrates in one 

 of the floor cases, and in the second floor case are brought together 

 characteristic vertebrates and invertebrates peculiar to the islands 

 of the Pacific. 



The Library consists of 44,558 volumes, and 40,266 pamphlets; 

 1,040 volumes, and 2,240 pamphlets have been added during the 

 year.

 and the Annual Report, a total of 578 (78 quarto, 500 octavo) 

 pages, with 59 (15 quarto and 44 octavo) plates have been issued 

 and are listed on pages 41-42. The two Memoirs and three of 

 the Bulletins contain reports on the scientific results of explorations 

 carried on under Mr. Agassiz's direction, one Bulletin contains a 

 report upon the " Albatross" Echini collected in 1906, one Bulletin 

 is a Contribution from the Zoological Laboratory, three Bulletins 

 are Contributions from the Geological Laboratory, and seven
