[97] APTERYGOTA 95 



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



Four types, Muir Glacier ("hillside to right"), June n, 1899 

 (No. 68). 



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

 ('73' P- 39) Dut the two 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 marginata 

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

 have been furnished me by Dr. Schaffer. 



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

 ington, who has materially assisted in extending our knowledge of 

 Arctic Collembola.
