could be found in structures not usually alluded to in taxonomic work, 
and what variation was exhibited by the various parts of the body. In 
the course of this work we came to the auditory ossicles, and soon be- 
came convinced that these little bones were of great interest and value 
for taxonomic studies. In order to gain a wider acquaintance with the 
modifications exhibited, we borrowed African skulls from the U. S. Na- 
tional Museum, and a series of South American skulls from the Ame- 
rican Museum of Natural History. The present short paper describes 
and figures the African specimens collected by the Smithsonian Expe- 
dition to British E. Africa. 
Describers of rodents lay stress on the form and size of the external 
ear and of the auditory bullae. It is very easy to lay bare the auditory 
ossicles on one side, without seriously damaging a skull, and there seems
