SPECIES OF MAMMALIA. 



Order III.— CARNASSIERS. 



Teeth of three sorts, incisives, canines, and cheek teeth, 

 more or less of a trenchant or carnivorous character. Ar- 

 ticulation of the lower jaw crosswise, so as to prevent any 

 other than a vertical motion. Orbits not separated from 

 the temporal fossae. Zygomatic arch wide and elevated. 

 Thumb of the anterior extremities never opposable to the 

 other fingers or toes. Stomach simple, membranaceous. 

 Intestines short. 



Eats more or less of animal and vegetable matter in the 

 different species, but never grass or leaves. 



Habits various. More or less savage, as their physical 

 traits are more or less of a carnivorous character. 



Inhabits nearly all the habitable parts of the globe. 



This order is divided into four families, viz. 



1. Cheiroptera. 



2. Insectivora. 



3. Carnivora. 



4. Marsupiata. 



Family I. — Cheiroptera. 



Fingers of the anterior extremities connected by a mem- 

 brane, which spreads from the anterior to the posterior 

 extremities, and in many of the species also connects the 

 latter to each other, forming altogether an apparatus more 

 or less effective for flight. Incisives various in number. 

 Canines more or less strong. Cheek teeth, in general, 

 having their crowns furnished with several acute points; 

 but in the first group of the first genus a single regular 

 furrow or indentation passes along the whole series, both 

 sides of each tooth approaching the figure of the transverse 

 section of a cone, a little convex, notched on the upper 

 edge from right to left. Mammae, in genera!, two, pectoral.
