on the inside of the teeth than on the outer. They increase in use 

 evenly and rapidly, so that the one contiguous to the molars is tin- 

 highest tooth in the jaw, excepting the canine, and even to that it 

 is not greatly inferior. 



The only peculiarity I am ahlc to note respecting the true molan 

 is, that the first has its anterior inner cusp so much produced as to 

 be nearly even with the outer anterior one, usually much the highest. 



The numeration of the teeth may he thus stated : — 



T 2—2 r , 1 — 1 n 2—2 -ir i 3—3 lfl 



In. -j-; Can. — ; Prem. — ■ ; Mol. — =-. 



The dimensions in column 1 of the following table are those of a 

 specimen from lhinnatt ; 2, those of one from Sicily : both lire- 

 served in spirit. Column 3 contains the dimensions of "the mutilated 

 skeleton, which is all that remains of the type of Prince Bonaparte's 

 Miniopteris Ursinii', whilst column 1 refers to a specimen collected 

 in Algeria in 1856 by the Rev. II. B. Tristram, and very kindl\ pre- 

 sented to me ; and columns 5 and (i refer to specimens from Lake 

 Ngama, collected by Mr. Anderson. The three last-mentioned spe- 

 cimens are all preserved in skin, and their dimensions are therefore 

 less to be depended on than those of the specimens in spirit.
