In noting the species of parasites under the various 

 hosts, it has been extremely diflicult to determine what 

 records should be acce))ted and what ones should be 

 rejected. As nearly all of Ihe older recoids are bas.-d 

 ui)on determinalitnis by e.xlernal form inslead of in 

 Ici-nal inialdiiiy, f bi'lieve Ihe lime lias come when we 

 should b.-iii an eiiliivly le'W scrii^s of records of

.Ml records of la|iewor.iis, except in llw case of lyp.- 

 specimens where the (leteniiiim I ion has been riia.le
