335169. Adult female. "Arroyo Eke," Territory of Santa Cruz, Argen- 

 tina. May 24, 1898. Collected by Albert E. Colburn. Original num- 

 ber 362. Received from the Princeton Museum of Zoology, where it 

 was No. 7939. 

 The barbarous word "Eke" (on the original label) or "Aike" (on the map 

 accompanying the official reports of the Expedition) seems to mean a camp- 

 site. The locality "Arroyo Eke" is nowhere mentioned in the reports, but 

 the whole of the period from May 3 to June 29, 1898, was spent by Hatcher 

 and Colburn at "a number of springs near a fine meadow, which ... lay 

 a short distance to the west of Swan Lake" (see Hatcher, Princeton Univer- 

 sity Expeditions to Patagonia 1 [Narrative and Geography] : 188-190, 

 1903). Swan Lake is a small body of water fed by Spring Creek, a stream 

 flowing eastward from the eastern base of Mount Belgrano. The provenience 

 of the type specimen thus seems to be along Spring Creek, just west of its 

 debouchment into Swan Lake.
