Mallophaga of the Canadian Arctic Expedition, 1913-18. 
A. W. Baker, Ontario Agricultural College, Guelph. 
The Mallophaga taken on the Canadian Arctic Expedition comprise a 
small collection of twenty species occurring in eleven genera. These parasites 
were taken from thirteen species of bird hosts and one mammal. The collection 
shows three new records for America, and a considerable number of new host 
records. The specimens were collected by Mr. Frits Johansen and other 
members of the expedition. 
In preparing this list I have followed Harrison's generic classification, and 
also have followed his specific synonymy. The result is that a number of 
common species appear under names which have not previously been given 
them in papers from this continent. I have also followed Harrison in 2;iving 
the original bibliographical record for Nitzschian species. 
Since the districts where the collections were made are so infrequently 
worked over I have included the dates of collections for the possible benefit of 
future collectors. Considerable collections of Mallophaga from Alaskan birds 
have been worked over by Kellogg and others, and where these workers have 
made previous records from Alaskan birds of one of the species occurring in 
this coUectioi, I have made mention of the record. 
I append figures of seve.al forms which are new American ecords or of 
which descriptions and figures may not be readily available to Canadian students. 
I am much indebted to Mr. G. F. Ferris, of Leland Stanford Junior Uni- 
versity, for examining a number of species in the collection and comparing them 
with material in the University collections. I am also indebted to Mr. H. G. 
Crawford, of the Department of Entomology, Ontario Agricultural College, for 
preparation of the material for microscopic examination.
