ectoparasitic existence. Furthermore the genus Eoctenes , at least, exhibits a 
remarkably catholicity of taste as to hosts and an even greater discon¬ 
tinuity of geographical distribution. It should further be noted that no 
Polyctenid has yet been reported from a bat of the family Vespertilionidae.

Inasmuch as this is one of the oldest and largest families of bats, such 
negative evidence may be of more than usual significance. 
Table I has been changed in certain details from Ferris and Usinger 
(1939) to conform to Allen’s views. Thus the host of Polyctenes molossus 
is assumed to have been a Nyctinomus rather than a Molossus as originally 
reported because we are told that Molossus is a new world genus and is 
replaced in the old world by Nyctinomus. Even more changes will be noted 
in Table II which summarizes the most recent views on the systematic
