is illustrated with photographs of both sexes feeding from the 

 interstices of the host's shields. Our Torit adults, however, 

 were taken in the host's axillae (diiring a native big-game hunt 

 and stored in a himter's ear, plugged with mud, for three hours 

 until our lost vials coiiLd be recovered). 



DISEASE RELATIONS 



Experimental attempts to transmit heartwater ( Rickettsia 

 ruminantium ) of cattle by this tick species have failed. 



It is claimed that specimens have been found infected with 

 Q fever (Coxiella burnetii ) in Portugese Guinea. 



As with the Aponomma parasites of lizards and snakes, it is 

 of interest to conjecture that the small reptile-amblyomma may 

 be a vector of the hemogregarines of tortoises. 



REMARKS 



Misshapen specimens have been reported (Santos Dias 19^9B, 

 1950A,1955A). 



Amblyomma werneri werneri Schulze, 1932(A), described from 

 Kinixys b. belliana (see Werner 192/i.) from Talodi, Kordofan, Sudan, 

 appears to be a synonym of A. nuttalli . Follov/ing Schulze 's 

 practice of applying species names to any variant, he distin- 

 guished a single specimen as different from A. nuttalli for the 

 following reasons; the dark marking not bla"ckish-brown, but light 

 red brown on a light reddish brown backgroxmd; darker markings 

 boiinded with a coppery color (in A. nuttalli dark yellow brown 

 without copper borders); median stripes more irregular than in 

 A. nuttalli and broadened at the ends; lateral groove sharply 

 defined against the scutum, in A. nuttalli irregular; and ventral 

 median muscle plate smaller. 



All characters proposed to separate A. werneri from A. nuttalli 

 fall well within the normal range of vari'ation due to age"7 nutrition, 

 or methods of preservation. In long series of any Amblyomma species.
