 occupies the greater portion of each of the bristles exhibits a 

 chant,cable metallic lustre, varying m diiferent positions from 

 deep steel-blue to bright copper-red. The length of the body

* " The deep sulci on the anterior surface of the incisor teeth of the 

 upper jaw are situated nearer to the inner than to the outer edge of the 

 tooth, and divide its face into thiee ridges, the inner of which is half the 

 breadth of the middle, and the middle less than half the breadth of the 

 outer. The molar teeth of the upper jaw have two re-entering fold.s of 

 enamel on the outer, and one on the inner side ; the outer passing be- 

 yond the middle of the crown, the inner centr.d and less deeply entering: 

 all the teeth are nearly equal in size; the anterior three are nearly 

 square ; the posterior somewhat rounded : there is no notching on the 

 outer edge, but a distinct notch exists where the enamel folds in on the 

 inner side, especially of the three posterior teeth. In the lower jaw the 

 tirst molar has three folds of enamel on the inner side passing beyonil the 

 middle of the crown, and one small fold slightly notched on the outer : 

 the second and third have two inner folds and one outer, all notched at 

 • the edge: the posterior is nearly similar, but more rounded bebiud* 

 This system of dentition bears a greater resemblance to that of Erdhizottf 

 F. Cuvier, than to that of any other genus of the Rodcntia."
