umbia, Western Oregon and Washington we find average unalasch- 

 ensis. Two winter specimens from Vancouver Island show the 

 extreme of the melauistic coast tendency, being nearly black and 

 very dark specimens from Kalama, Washington and Humboldt 

 Bay, California, show the direction and extent of the migration of 

 this phase along the coast. Alaska specimens are lighter, three 

 from Koniuski Island being nearly as light above as schistacea, so 

 that extremes of dark and light from south and north, respectively, 

 appear like distinct species, but they are connected by a perfect 

 intergradation. Winter specimens of schistacea all come from Cali- 

 fornia, while all Oregon specimens are winter unalaschensis. Brit- 

 ish Columbia thus forms common ground for unalaschensis and schis- 

 tacea, the Cascades being the habitat of intermediates in the breed- 

 ing season. Unalaschensis breeds on Vancouver Island and north- 

 ward. While unalaschensis from north Alaska is nearly as light 

 as schistacea, there is a marked difference between the two, the for- 

 mer retaining the broAvn shade above as contrasted with the ashy 

 cast of upper parts in the latter. 



198. Pipilo muculatus megalonyx. Spurred Towhee. 



Abundantly haunting the woodlands of the interior in all locali- 

 ties visited, up to 4,000 feet. 



199. Pipilo maculatus oregonus. Oregon Towhee. 



Replacing megalonyx west of the Cascades. Its exact counterpart 

 in habits and habitat. 



200. Habia melanocephala. Black-headed Grosbeak. 



Not met with alive. Many skins from parts of Washington and 

 British Columbia examined. 



201. Passerina amoena. Lazuli Bunting. 



This beautiful finch is very abundant between the coast range 

 and the Rockies, but does not extend farther north than Bonaparte. 

 Its habitat, in this respect, coincides with that of other species of 

 southern extraction in British Columbia. 



202. Piranga ludoviciana. Louisiana Tanager. 



Fairly abundant and uniformly distributed over the coasts, 

 islands and mainland of Washington and British Columbia. 



203. Progne subis. Purple Martin. 



Only one specimen, a male from Victoria, being secured, it is dif- 

 ficult to state whether the Martins of Vancouver Island belong to
