Description based on two Js and seven ? s found on sheep in Eastern 

 Cape Colony (Lounsbury coll.). We have examined specimens kindly 

 lent us by Prof. Neumann and others (in W. F. Cooper's coll., determined 

 by us) from goats, Albert District, S. Africa, 1905 (H. E. F.). This 

 tick is supposed to inoculate an obscurely defined disease characterised 

 by anaemia.
