their call, like the wag of a barking dog's tail, but nothing 

 could make the bird more conspicuous nor more surely attract 

 its enemies, and this must largely offset the advantage of its 

 protective colors. 



Breeds within the Arctic Circle. (MacFarlane.) 



Eight specimens secured; 6 5, i ?, 1 j'uv. 



Aegialitis vocifera (Linn.). Killdeer. Not common. 

 Seen only along the shore of the lake, where the previous 

 species was abundant. The above remarks in regard to 

 the protective coloration being nullified by conspicuous vocif- 

 erations and actions, are even more applicable to this species. 

 Killdeers are constantly making as much noise as possible, and 

 inviting destruction by following up the collector with their 

 incessant clamor. They are said to warn ducks and other 

 game birds of the approach of the hunter, a case of disinter- 

 ested interference with other people's business that no collec- 

 tor or hunter will regard with favor. 



But one specimen secured, although several were seen. 



Aegialitis semipalmata (Bonap.). Sani-pahnatcd PJoz-er. 

 Rare. Onl}- one specimen secured. I do not recolkct seeing 

 others. 



Breeds on coast of Arctic Ocean. (MacFarlane.) 



Order GALLIN^E. Gallinaceous Birds. 

 Family tetraonid.e. Grouse, Partridge, etc. 



Dendragapus canadensis (Linn.). Canada Grouse. Two 

 specimens secured, male and female. The male is an inter- 

 esting specimen, as it intergrades, apparently, with D.frank- 

 limi, having the characteristic white tipped tail-coverts of that 

 species in connection with the broad orange-brown tips of 

 the rectrices of D. canadensis. The following is a detailed 

 description of this specimen : 



Above, head and neck closely barred with black and rusty; 

 back with broader bars of black and grayish brown; super-
