Mallophagan parasite, Trichodectes parumpilosus, while 

 the horse and donkey have another common biting louse, 

 Trichodectes pilosus. Two varieties of Trichodectes 

 parumpilosus have been named by Piaget, one from the 

 zebra and another from " little horses of Java." 



The pigs (family Suidaa), of which three wild African 

 species besides the familiar animal of the barnyard are 

 found in the host list, are infested by two (perhaps three) 

 species of Anoplura and one (a not too certain record) 

 Mallophagan. Hmmatopinus suis is found on the domes- 

 tic Sus all over the world, while Hcematopinus latus of 

 Neumann, II . phocochoeri of Enderlein and H. peristictus 

 of Kellogg and Paine, which are almost certainly all one 

 species, are recorded from the wart hog, Phacochcsrus 

 a-thiopicus from Xyasa-land, Africa, and probably also 

 from another wart hog species from Africa, and the Eed 

 River hog, Potamochcerus chceropotamus from Nyasa- 

 land, Africa. In addition Potamochcerus demanis (prob- 

 ably), from German east Africa, is credited by Stobbe 

 with a Mallophagan parasite peculiar to it, Trichodectes 

 vosseleri Stobbe. 



The peccary, Dicotyles tajacu (family Dicotylidae) of 

 Central America and southwestern North America, has a 

 Mallophagan species peculiar to it, belonging to the 

 smaller of the two large Mallophagan genera, namely, 

 Gyropus. 



The dromedary, of north Africa and western Asia, and 

 the bactrian camel, of central Asia, harbor a common 

 sucking louse, Hcematopinus cameli. A doubtful second 

 species called H. tuberculatus (Neumann thinks it iden- 

 tical with cameli) has been recorded from a dromedary 

 imported from India into Australia. The * 'South Amer- 

 ican camel," the llama, harbors an Anopluran species 

 peculiar to it, and two Mallophagan species, Trichodectes 

 hreviceps Rudow and T. inaqualemacidatus Piaget. Al- 

 though Rudow's species are often suspect, I have just 

 had his hreviceps from a llama of Peru (collector C. H.
