of an upper jaw with its three most charac- 

 teristic molars. They are well preserved and 

 so distinctly dog as to leave no doubt as to 

 their identity. These teeth would indicate an 

 animal about the size of a Newfoundland dog. 

 This one was described a few years ago in a 

 paper read before the Academy of Sciences 

 of the University of Oregon. The descrip- 

 tion was published in the transactions of the 

 academy under the name of Canis Shoshonen-

 Fork of the John Day river by a man who 

 was in the writer's employ in 1894. 



The small dog's head given on Plate XIX 

 was taken from the fossil beds of Bridge creek, 

 several years ago, by J. W. Cusick, an Albany 

 banker. The writer once found in these lower 

 beds the molar teeth of a fossil dog, which 

 were twice the size of those of our largest 

 Newfoundland.
