Mallophaga of the Canadian Arctic Expedition, 1913-lS. 



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 giving 

 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 collectioi, I have made mention of the record. 



I append figures of sevei 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 coUectioji and compariag 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.
