Milk dentition. — There are three specimens, a right 

 (Cat. No. 1 ^) and a left (Cat. No.^ 56 ) maxillary and 

 a right mandible (Cat. No.~-) ? containing milk teeth. 

 The two maxillaries do not seem to pertain to the same 

 individual, as in one the teeth are somewhat smaller. 

 Each contains three teeth preceded by a single empty 

 alveolus in front of which the bone is broken away. The 

 larger individual contains a portion of another molar, 

 only a tip of which protrudes, while the broken hinder sur- 

 face of the other specimen shows a very distinct tooth 

 impression. There is nothing distinctive about the two 

 posterior teeth, which are typical molars, except that the 

 external column of the postero-external crescent is more 

 distinct than in the adult teeth. The anterior of the pre-
