comparisons with a few orders. These are the Insectivora, Ifarsiijnalia, and 
some of the Prosimics, which have small brains. Other characters, however, 
exist, which add to the reasons for separating them from the Carnivora. 
There is nothing in the dentition inconsistent with the orders Carnivora^ 
Insectivora, and Marsnpialia. It resembles that of some Viverridce of the 
first, JSIysknnys of the second, and the SarcojjJiaga of the third. Neverthe¬ 
less, in the often limited number of incisor teeth, it approaches most nearly 
to the Insectivora. 
The transverse glenoid cavity is that of the three orders named, and 
distinguishes the group from the Piodentia. 
So far as known, the coossification of the scaphoid and lunar bones, the 
distinguishing character of the Carnivora, is wanting. The angulate shape 
of the ilium is that of Insectivora and Marsuyialia. It is less apparent in 
Cliiromys, and is not characteristic of the higher Mammalia. The large 
anterior inferior tuberosity is especially a character of the Lemurs, other 
than NycticehincR (Mivart),* * * § the Cliiromys, and of certain Insectivora, 
especially Solenodon. It is figured by Mivart in Indris and Loris, by Owen 
in Cliiromys, f and by Peters in Solenodon. f It is absent in Carnivora, the 
true Quadrumana, Marsnpialia, and many Insectivora. Allman § does not 
represent it in Mystomys. The third trochanter of the femur is wanting in 
the Gyrencephalous orders generally, characterizing only the Perissodactyla. 
Among Lissencephalous orders, it is very common in the Edentata, and still 
more usual in the Insectivora. It does not occur among Marsupials. But 
in the Prosimice, there is often a third trochanter (Mivart, 1 . c.; c. g.. Lemur, 
Galago'). In Talpa and some other Insectivora, and also in Cliiromys, it is 
situated high up, nearly opposite the little trochanter. 
In the tibio-tarsal articulation, this group resembles no living genera 
with which I am acquainted. So far as the tibia is concerned, it is remark¬ 
ably like that of the Ungulate genus Comjplwdon, but the astragalus is very
