remains to be discovered. All the members of the group 

 are characterised by the presence of a large descending 

 flange from the inferior border of the zygomatic arch, while 

 most of them have a second projection descending from the 

 chin. The European Entelodon, as shown by its enlarged 

 premolars, is a more specialised form than the American 

 Archceotherium ; the most specialised of all in this respect 

 being the Indian Tetraconodon, in which the premolars were 

 enormous. So far as can be judged from their osteology, 

 coupled with the undoubtedly omnivorous character of their 

 dentition, 'their long limbs, and their wide geographical dis- 

 tribution, it seems highly probable that these giant swine-like 

 animals were capable of adapting themselves, when necessary, 

 to changed conditions of environment. 



Certain remains from very superficial beds in South Africa 

 have been considered by Dr. R. Broom to afford sufficient 

 evidence for naming a new species of hartebeest {Bubalis priscus) 

 and another of Eqnus, namely E. capensis ; the latter being 

 distinguished from other members of the genus by its superior 

 size. Dr. Broom's papers appeared in the third part of vol. vii. 

 of the Annals of the South African Museum, issued on April 28, 

 1909. The exact date of publication in this instance is a matter 

 of some importance, for in the October issue of the Proceedings 

 of the Zoological Society Prof. W. Ridgeway has described, 

 under the name of E. hollisi, the fore part of an equine jaw from 

 a presumed late Tertiary deposit in British East Africa. 



A brief reference will suffice to Mr. W. J. Sinclair's mono- 

 graph of the Typotheria of the Santa Cruz beds of Patagonia, 

 published in the Memoirs of the Princeton Expedition, to Pata- 

 gonia, since it is in the main only an expansion of the preliminary 

 paper published in 1908 on the same subject and mentioned 

 in my article in Science Progress for that year. 



Passing to the Proboscidea, attention may be directed to the 

 description by Dr. C. W. Andrews in the Geological Magazine for 

 1909 (pp. 349, 350) of a new mastodon {Tetrabelodon dinotheriodes) 

 probably from the Loup Fork beds of Kansas. The species is 

 founded on a lower jaw in which the symphysis is bent down, 

 so that the incisors were apparently almost vertical. 



Here it may be conveniently mentioned that Prof. H. F. 

 Osborn has contributed a note to Nature (vol. lxxxi. p. 139) 

 on the probable feeding habits of the Egyptian Tertiary genera
