in 1870 from a porcupine {Erithizon epixantJms) in Idaho, and that it 

 was also taken in Wyoming in 1873 from a rabbit {Lepus Bairdii). If 

 the determination was correct, these must have been ticks carried 

 north by Southern cattle, for B. amvulatus does not normally occur 

 so far north. Murray (1877, pp. 193, 191) says that a 

 specimen was taken from a miner's neck in Utah, and he 

 thinks that the tick on the moose referred to by Capt. 

 Campbell Hardy (Forest Life in Acadie, 1869) is identical 

 with this form. It seems more probable, however, that 

 Hardy's form is Dermacentor variegatus^ and there are 

 some doubts in our minds regarding the correctness of 

 the determination in the Utah case. 



Curtice (1891) proposed Ixodes horns as type of a new 

 genus, BoojMlus. It was also Curtice who suggested that 

 this species was possibly identical with Ixodes 

 ammlatus and Hcemaphy sails rosea. Curtice's 

 genus BoopJdlus has been generally accepted by 

 American authors, but was rejected by Neumann (1897), 

 who placed B. homs in Mhipicephcdus a^ B. annulatxis. 

 Neumann unites under this species the following forms: 

 Ixodes annulatus Say, 1821; Hmiiaj^hysalis rosea, Koch, 1841; 

 Ixodes lovis Riley, 1869; ''I DugesiV of Megnin, .1880; 

 Hcemaphysalis microtia Canestrini, 1887; Boophilus horns 

 (Riley); Rli. calcaratus (Birula), 1895; Bh. annulatus cau- 

 datus. 



Fuller (1899) compared the North American, the Austra- 

 lian, and the South African forms and considered that they 

 represented distinct species (see below, p. 130). He follows Neumann 

 by not adopting Boophihis.
