than any other arthropod. This variety is said to be greater on 

 continental Africa than anywhere else in the vorld. Other injxiry, 

 apparently due to toxins, in the form of tick paralysis may be 

 locally important. Death, lameness, or serious debilitation of 

 the jst by exsanguination or as the result of secondary infec- 

 tions at the site of attachment is not uncommon. Economic loss 

 due to nximerovis punctures of animal hides by the raouthparts of 

 large ticks is frequently reported.
