This study of the parasitic Arthropods of domestic and wild animals 

 of the Argentine Republic and neighbouring countries has been 

 undertaken in view of the increased interest in the subject from the 

 point of view of the transmission of disease. A key is given to the 

 species of ticks known to occur in the countries investigated, including : 

 Argasidae, Argas persicus, Ok., a common parasite of domestic 

 poultry, to which it transmits spirochaetosis, living in the crevices 

 of hen-coops and pigeon-houses and attacking the birds at night 

 Ornithodorus megnini, Dug., is frequently found in the ears of sheep, 

 cattle and llamas and sometimes of man, particularly children. 

 O. talaje, Guer., recorded from Asuncion, Paraguay, is found in 

 cracks in the walls of houses and hen-coops ; this species remains 

 hidden during the day and attacks both man and animals in the night, 

 0. turicata. Dug., is parasitic upon man and pigs and is probably 

 identical with 0. rostratus, Arag., which is believed to be the 

 transmitter of relapsing fever in Colombia. 



Representatives of the Ixodidae include Amblyomma cdtiplanum, 

 Dios, abundant on llamas and apparently peculiar to this host ; 

 A. agamum, Arag., found on a snake, Xenodon merremi, investigations 

 on this species indicating that it is parthenogenetic, though this has 

 not been definitely proved ; A. brasiliensis, Arag., from Paraguay ; 

 A. cajennensis, F., which is widely distributed in sub-tropical America, 

 attacking man as well as practically all domestic and wild animals ; 

 A. maadatum, Koch, which is common in Argentina, the habitual 

 host being the dog, though cattle, deer and sometimes horses are also 

 attacked; A. testudinis, Con., taken on tortoises; and Boophilus 

 {Margaropus) annulatus var. niicroplus, Can.
