APTERYGOTA 97 



Type. — Cat. No. 5509, U. S, Nat. Museum. 



Four types, ISIuir Glacier ("hillside to right"), June 11, 1899 

 (No. 68). 



In coloration E. kincaidi is much like E. griseo-olivata Pack. 

 ('73' P' 39) ^"^ ^^^ ^^^'^ species differ sufficiently in structural details. 

 In Packard's species the inferior claws are basally dilated, the mucrones 

 strongly falcate, and the fourth abdominal segment is four times as 

 long as the third. 



Next to griseo-olivata., kincaidi is most nearly allied to i7iarginata 

 Tull. and inuscoruDi Tull. (not Nic), European specimens of which 

 have been furnished me by Dr. Schiiffer. 



Named after Professor Trevor Kincaid, of the University of Wash- 

 ington, who has materially assisted in extending our knowledge of 

 Arctic Collembola.
