 deer, or the camivora, we find, first, that the region of the 

 spinal column is marked by a dark stripe ; secondly, that the 

 regions of the appendages, or limbs, are differently marked ; 

 thirdly, that the flanks are striped or spotted, along or be-

shoulder and hip regions are marked by curved lines ; fifthly, 

 that the pattern changes, and the direction of the Hues, or 

 spots, at the head, neck, and every joint of the limbs.; and

 caterpillars, similar spots and markings are repeated in each 

 segment, except where modified for some form of protection.

 colours and markings follows generally the same law. The 

 crown of the head, the throat, the ear-eoverts, and thr

 and the under tail-coverts. 1

 certain directions forminglines or bands; and, these again, some-
