agree with known, but poorly described, European forms. Thanks to 

 the careful work of a nixmber of investigators at Konigsberg and at 

 Basle, the latter are being steadily worked up and it is planned to 

 effect the same result here. In view of the large number of forms yet 

 unknown is seems wise at present, however, to withhold all names 

 rather than to publish many blanks in the list. Of many forms more 

 material is needed for the determination of that now in hand and any 

 gifts will be gladly received. Specimens can be preserved with ease in 

 formol (5 to 10 per cent), better if a few drops of acetic acid has been 

 added, and sent in this fluid or in alcohol. The head of the parasite is 

 of importance for the determination of the species as are also the ripe 

 segments at the opposite end of the chain. 



The appended table gives a list of the species of birds thus far ex- 

 amined, the number of individuals found infected and free, and the 

 kinds of parasite represented. In arranging the list of hosts the num- 

 bers and names of the A. O. U. check list have been followed without 

 exception:
