American authors" record the following hosts of the tick in the 

 United States : Besides the type-host, Lepus palustris, the tick occurs 

 on 6 other species of hare and rabbit, these appearing to be the chief 

 hosts. Adults also occur on Felis domestica, robin, quail and meadow- 

 lark. Immature stages are abundant on quail and meadow-lark, scarcer 

 on chaparral cock and Breivers blackbird (assuming that they were 

 rightly determined, the immature stages are also found on thrush, field- 

 lark, jackdaw, blue jay, magpie and pine squirrel). Rabbits are nearly 

 always infested about the head, on the crest and occasionally about the 

 ears and eyes; when heavily infested '" the rabbits are often much 

 weakened and can be easily captured.
