species, including the domestic dog, a wild dog of South 

 America, two wild dogs of Asia, two foxes, and a wolf. 

 The domestic dog has a familiar sucking louse and is also 

 credited with that problematical normal or straggling 

 biting louse of a peculiar genus which I have referred to 

 in my account of the parasites of the kangaroos Tricfoo- 

 dectes latus, the common biting louse of the domestic dog, 

 is also common to the wolf, Canis lupus, of Europe and 

 Asia, and to the raccoon-like wild dog, Nyctereutes pro- 

 cyonoides, of Asia and Japan. The record of this last 

 came, it must be noted, from the Berlin Zoological Gar- 

 dens. There is no other record of commonness of para- 

 site to two hosts in the family. The English fox has a 

 single Mallophagan species, and the California fox has 

 another. The dhole, a wild dog of the Himalayas, has a 

 Mallophagan species, and the Magellan wolf of Patagonia 

 has another. 



The family Procyonidse is represented in the host-list 

 by two raccoons, the California ring-tailed cat, and two 

 coatis of Central and South America, respectively. The 

 two raccoons, Procyon lotor of North America and Pro- 

 cyon psora of California, harbor a common Mallophairnn 

 parasite. In addition a German record (from a zoolog- 

 ical garden?) credits Procyon lotor with carrying also a 

 M;ill»ipli;m';ui which is the characteristic parasite of the 

 badger. On the California ring-tailed cat, Bassariscus 

 astnta, have been found two Mallophagan species, one of 

 which is the characteristic parasite of the skunks of 

 North and South America. The two coatis, Nasua narica 

 and Nasua rufa, one of southwestern United States, 

 Mexico and Central America, and the other of South 

 America from the equator south, both harbor a common 

 Mallophagan species. 



The family Mustelidae, comprising the badgers, wea- 

 sels, martens, and skunks, an ill-smelling crew, offers no 

 attraction to blood-sucking parasites, but is represented 

 in the host-list by nearly twenty species from which 

 Mallophaga have been taken. The Old World badger has
