by Mr. Packard ^ from Okak, two hundred miles east of Ungava. 

 Mr. Mcllwraith sends three si^ecimens labelled "Labrador." Of 

 these probably two were taken south of the habitat of ungava and 

 within the range of hudsonicus, with which form they seem to 

 perfectly agree. ^ The range of ungava is probably coextensive 

 with that of the Arctic Realm across northern Newfoundland. 

 Its westward extension to and beyond the shores of Hudson's Bay 

 can only be conjectured. 



Average tneasurements of 15 adults:— SN\ng,6<,.s mm- (63 to 68) ; tail 65, 

 (63 to 68) ; tarsus 16.2 (16 to 16.5) ; bill from nostril, 7 (6.5 to 7.5).

3. Parus hudsonicus stoneyi Ridgiv. Kowak Chickadee. 

 Habitat. — Northwestern Alaska. 



Mr. Ridgway's description of this race not only ignores any 

 subdivisi on of the species hudsonicus but contains no reference to 

 the evura of Dr. Coues with which it is almost identical in 

 measurements. Tiie special characters given by Mr. Ridgway to 

 stoneyi are, however, in no sense synonymous with those of 

 evura as stated by Dr. Coues. Sioneyi is characterized -as 

 "similar to hudsonicus but inuch grayer above, sides of neck 

 purer ash gray, sides much paler rusty and throat clear slate 

 black instead of sooty blackish." The measurements given for 

 stoneyi by Mr. Ridgway are greater than his measurements of 

 hudsonicui though he included under that name all the rest of the 

 group, but he makes no reference to the comparative size of 

 stoneyi., probably from the very reason that other Alaskan birds 

 were as large. On the contrary Dr. Coues bases his evura solely 

 on the larger size of Alaskan birds as compared with eastern ones 

 and takes care to state that Alaskan birds retain the precise color- 

 ation oi hudsonicus. My examinations of the two original speci- 

 mens oistoneyi, which still remain the only adult representatives 

 of their race in collections, fully confirm the value of the color 

 diagnosis given to this form by its describer. It may now be 

 more fully characterized as the palest of the group with wing 

 measurements about the same as ungava, the bill being stouter

''Mr. Mcllwraith has since written me they all came from "southern Labrador."
