MAMMALIA 



I. A study of the rnammalian skull. Time will not admit of a 

 careftil study of the skull' of any one species. Figures 3, 4,

 identification, of skull characteristics. The study of the skull 

 of any given species is optional with the student. 



II. Identification of species. Write the tooth formula of each 



species identified.
