rig. Q. Showing manner of occurrence of certain mammals of the Stikine 

 region. Species and subspecies primarily of the coast are listed in the left-hand 

 column; those of the interior in the right-hand column. The intervening columns 

 indicate collecting stations of the 1919 expedition, from the coast toward the 

 interior, reading from left to right, with the approximate distance of each place 

 from the coast. Arrows indicate direction and extent of dispersal of each species 

 from the center of abundance. 



The 127 species and subspecies of birds treated in this report prob- 

 ably form a fairly complete representation of the summer avifauna of 

 the region. It seems curious, though, that we should have seen no 

 three-toed vsroodpeckers (Picoides), no magpies {Pica), and no yellow- 

 throats (Geothlypis) . 



Numerous species of the mammals known to occur in the region 

 we did not meet. We caught glimpses of bats on two occasions, but 

 got no specimens. A coyote {Canis) is said to range this far north, but 

 we neither saw nor heard one. Vulpes, Martes, Gulo, and Lynx are 

 fur bearers that are regularly trapped throughout the region. Whether 

 or not there are seasonal differences affecting local distribution we did
