THE MALLEUS OF THE LAOEHTILIA, ETC. 587 



Leaving aside the latter question, to which M. Albrecht pro- 

 poses to return shortly, the attempt will be made to demon- 

 strate the correctness of his views by the former method. 



Nevertheless, before this interesting subject is commenced, 

 it is indispensable to determine the morphological value of the 

 malar bone of Mammalia, since this determination will be of 

 the greatest utility in the sequel. 



In a recent work^ M. Albrecht has proved that the malar 

 bone of Mammalia ought to be considered as formed of three 

 parts, which he calls 



1st. A premalar. T 



2nd. A postmalar. . > See the Figs. 1, 2, 3, 4, below. 



3rd. A hypomalar. J
