122 Book-lice and Bark-lice; Biting Bird-lice 



Malloi)haga, has been found only on the guinea-pig. Washing the body of 

 the infested animal with kerosene emulsion (see p. igo) is [jrobabiy the 

 mos' effective remedy for biting lice. 



Of the nearly three hundred species of Mallophaga which I have recorded 

 (Proc. Nat. Mus., v. 22, 1899, PP- 39~ioo) f''o'" ^^''W North American birds, 

 mention may be made of the largest, Lccmobothnum loomis, taken from the 

 Canada goose; of Docophorus communis (Fig. 152), the most abundant and 

 widely distributed parasite of perching and song birds; of the pretty Nirmits 

 jclix (Fig. 153), with its dean v^'hite body and sharply marked black s[)ots; 

 of the fierce-looking Lipeiirus jerox, found on albatrosses; and of Amislrona 

 gigas (Fig. 154), found on fulmars, the broadest of the Mallophaga. 



As there are nearlv one thousand different species of North American 

 birds, and Mallophaga have been taken from l)ut two hundred and fifty of 

 them, it is obvious that the collector and student of these parasites has a 

 profitable field open to him.
