T. Townsend). With these llama Mallophaga there is 

 also a small Anopluran which I have not yet worked out. 



The family Cervidae is represented in the host list by 

 about ten species. They are infested by three species of 

 Anoplura, each peculiar to its host, and six species of 

 Trichodectes (Mallophaga) of which T. tibialis is com- 

 mon to the roe deer of Europe and Asia Minor, an 

 African Caprenhts, and our own black-tailed deer of the 

 western states. Trichnrfrcl Inuqicaruis is common to 

 the red deer of Europe and Asia Minor and the fallow 

 deer of south Europe, Asia Minor and north Africa. 



The giraffe (family Giraffidae) harbors a sucking louse, 

 Linognathus brericomis, peculiar to it. 



The great family Bovidas, with its many buffalo, buck, 

 sheep, goat and antelope kinds, is represented in the host 

 list by five or six species of Bos, four African bucks, 

 three or four sheep, the ibex, chamois and two or three 

 goats, and five or six antelopes, or gazelles. The domes- 

 tic ox, Bos taurus, harbors three species of Anoplura and 

 one Mallophagan. Curiously, none of these species is 

 recorded from any other Bos. On the other hand, the 

 zebu, the Indian buffalo, and the American bison all 

 have the same Anopluran species (and no other, nor any 

 Mallophagan), while the yak of central Asia and the 

 Kaffir buffalo each have an Anopluran peculiar to it. 

 The four species of African reedbucks and duikerboks 

 have, according to the records, each a peculiar species of 

 sucking louse. These records need scrutiny. One of 

 them is my own, but I had to describe the species without 

 seeing the types of the others. The domestic sheep 

 carries two Anopluran species and one Mallophagan. 

 The latter occurs also on at least two wild species of 

 Ovis, one of west Africa and the other of north Africa. 

 The fat-tailed sheep has a record from German south- 

 west Africa of a Trichodectes of its own. 



The domestic goat harbors one Anopluran and at least 

 one Mallophagan, the latter being common also to the 

 Angora goat, the chamois, and a wild ( ?) goat of Guinea,
