250 WHITE-BODIED CATERPILLAR-CATCHER. 



formation; but the bill of these is considerably 

 depressed. As representing the Glires, the greatest 

 number of the species are of a mouse colour, while 

 their analogy to the hedgehogs is shown by a pecu- 

 liarity in the structure of the feathers almost unique 

 in the class of birds. Upon pressing the fingers 

 against the feathers of the rump and back, it seems 

 as if they were intermixed with little spines or 

 prickles, from which circumstance the French have 

 termed them Echenilieurs. The curious reader will 

 find this singular formation explained at some length 

 elsewhere*. 



The most typical examples of this singular race 

 inhabit New Holland; to them we retain M. 

 Cuvier's original name of Ceblepyris ; they are 

 known by their superior size some being nearly 

 as large as magpies and by the great length of 

 their wings, which are pointed and reach to the 

 middle of the tail. The other group that M. 

 Yieillot's name should not be lost we denominate 

 Campephagas, it contains birds smaller in size and 

 differently coloured ; the wings are short and 

 rounded, and the rictus, or mouth, is furnished 

 with a few stiff bristles, indicating that they have 

 some of the habits of true flycatchers. Between 

 these two groups, but more closely allied to the first 

 than to the last, comes the species now before us. 

 As it is the only one yet known having a decided 

 white under plumage, it is easily recognised.
