Certain undoubted Ptilodus jaws from the Fort Union beds 

 are probably identical with two species of Hallodon described 

 by Professor Marsh from the Ceratops beds of Converse county, 

 Wyoming, while other species of Ptilodus have been found in 

 the Torrejon beds of northern New Mexico, thus giving new 

 evidence of the close affinity, if not identity, in part at least, of 

 these three formations. Zoologically, Mr. Gidley would remove 

 the Allotheria from the Prototheria, where they have been placed 

 by certain, authors and associate them with the Diprotodont 

 Marsupials, not as the direct forebears, bat derived from a common 

 ancestry somewhere in Jurassic or Triassic time. Finally Gidley 

 considers these creatures as frugivorous in habit, possibly living 

 upon small fruits and berries. e. s. l. 



7. Descriptions of two new species of Pleistocene ruminants of 

 the genera Ovibos and JBoot/ierium, with notes on the latter 

 gemis / by James W. Gidley, Proc. U. S. Nat. Museum, Vol. 

 xxxiv, pp. 681-684, with pis. lvii-lix and one text figure. — Mr. 

 Gidley here describes two new horned ruminants from post- 

 glacial deposits, though from widely separated localities, Michigan 

 and Alaska, the former locality yielding the Bootherium found 

 in association with a mastodon. 



Gidley expresses the opinion that the genus Bootherium, sup- 

 posed by some to be synonymous with Ovibos, the musk ox, is 

 valid and may represent a distinct subfamily of the Bovidrc.

1. British Association for the Advancement of Science. — 

 The seventy-ninth annual meeting of the British Association was 

 held at Winnipeg during the week beginning August 25. This 

 is the fourth meeting ot the series held outside of the British 

 Isles ; it was highly successful in attendance and still more in 

 the importance of the scientific work done, notably the inaugural 

 address of Sir Joseph Thomson, and the sectional addresses of 

 Profs. H. E. Armstrong (Chemistry), E. W. Rutherford (Physics) 

 and Dr. A. Smith Woodward (Geology) — see Science for Aug. 

 27, Sept. 3 et seq., also .Nature of Aug. 26, Sept. 2, etc. Numer- 

 ous excursions were held, including one extending to the Pacific 

 Coast. Dr. T. G. Bonney will be the president of the meeting 

 for 1910, to be held at Sheffield.
