92 Report of the President 



EXTINCT VERTEBRATES* 



Henry Fairfield Osborn, Honorary Curator 

 W. D. Matthew, Curator 



The limited appropriation for field work was supplemented 



by a special appropriation of the proceeds of sale of duplicate 



skeletons of Moropus from the Agate Quarry, 



enabling us to continue operations at that 



locality. 



In the early part of the year Associate Curator Brown in- 

 vestigated a number of prospects in Oklahoma and northern 

 Texas. 



Mr. Albert Thomson, assisted by Mr. George Olsen, con- 

 tinued operations during the summer in the great fossil quarry 

 at Agate, Neb. An extensive new cut was made 

 N X £ ed, w° n *° on ^ e nortn s ^ e °f the quarry. It proved, how- 

 ever, to be comparatively barren of fossils, the 

 layer thinning out all along this edge. From the richer part of 

 the quarry a section was selected especially suitable to be 

 preserved and exhibited at the Museum in the block. This 

 block, showing 16 skulls and corresponding numbers of skele- 

 ton bones within a space of 5^2 by 8 feet, was skilfully lifted, 

 boxed and brought to the Museum without damage. Its 

 weight when boxed was about 6,000 pounds. Several other 

 valuable fossil specimens were obtained from the quarry and 

 vicinity. 



In November, Mr. H. E. Anthony, assisted by Mr. Charles 



Falkenbach, undertook an expedition for living and extinct 



mammals, to the island of Jamaica. No fossil 



Expedition to vertebrates, except for a single skull of a marine 



Jamaica r ° 



mammal, were known from this island, but a 

 consideration of the conditions in this and other West Indian 



Under the Department of Vertebrate Palaeontology (see also page 216).
