In the literature, P. oorvi has been reported many times as the para- 

 site of the crow, Corvus braahyrhynchos . The type host for P. corvi is 

 the Common Raven and upon examination of Philopterus from both of these 

 birds it is obvious that the 2 species are not the same. Those P. 

 corvi found on the crow refer to Philopterus ocellatus osborni Edwards, 

 1952 inn for D. corvi Osborn, 1896).

After examining 27 blue jays, I cannot agree with the statement made 

 by Malcomson (1929) that, "I have found the blue jay to be very heavily 

 infested with this particular species of louse."
