the same region until August 27, when he started south, stopping 
September 3 and 4 at Thomas Bay and from September 10 to 17 
at Helm Bay, both being localities on the mainland between 
Juneau and Dixon Entrance. 
The expedition obtained 532 birds, 33 sets of eggs, some with 
nests, and 476 mammals. Notebooks were kept by most of the 
party, and upon these as well as the specimens the accompanying 
reports are based. The halftone illustrations are from photo- 
graphs taken by Miss Alexander. 
Miss Alexander has donated all of this material to the Uni- 
versity of California Museum of Vertebrate Zoology, constituting 
the first accession to its collections. 
The region dealt with is wholly within the faunal area first 
named by Nelson the Sitkan District. It is characterized by 
excessive humidity of the atmosphere and cloudiness, by rela- 
tively warm winters, as compared with the interior of North 
America on the same parallel of latitude, and by colder sum- 
mers. The vegetation is abundant and peculiar, the terrestrial 
animal life relatively less abundant.
