much paler throughout. * * * This form is strikingly paler than any of 

 the known races of Perisoreus canadensis. The contrast between the 

 white throat and the fore neck and the drab lower parts, so noticeable in 

 the other subspecies, is quite lacking." 



The above common name appears in the nineteenth supplement to our 

 Check-list (1944), where the present known range of the race is said to 

 be "central and southern Alberta." Its habits, so far as known, are in- 

 cluded in those of the type race. 



PEBISOREUS CANADENSIS NIGRIOAPIIXUS Ridgway 



LABRADOR JAY 



At long last the A. O. U. (1944) committee on nomenclature has 

 decided to admit to the new Check-list this fairly well marked subspecies, 

 which Robert Ridgway (1882) described many years ago as "similar to 

 P. canadensis funiifrons in darkness of coloration, but forehead, lores, 

 chin, throat, and sides of neck distinctly white, in marked and abrupt con- 

 trast with the dark color of adjacent parts; crown, occiput, and upper 

 part of auricular region decidedly black, with little or no admixture of 

 slaty anteriorly. Differing from true canadensis in much darker colora- 

 tion throughout, much blacker crown, black auriculars, less extensive 

 white area on forehead, and more marked contrast of the white portions 

 of head and neck, with adjacent darker colors." 



Dr. H. C. Oberholser (1914) proposed the name P. c. sanfordi for the 

 birds of this species found in Newfoundland, but this name has never 

 been recognized by the A. O. U. committee. I have collected birds of 

 this species in both Newfoundland and Labrador and have examined 

 large series of both in the museum at Cambridge, where we all agreed 

 that the Newfoundland bird is not sufficiently different from that of the 

 Labrador Peninsula to warrant its recognition in nomenclature. 



What we know about the habits of this race in Newfoundland and 

 Labrador is included in our life history of typical canadensis, which 

 was written before nigricapillus was formally recognized. 



PERISOREUS CANADENSIS BARBOURI Brooks 

 ANTICOSTI JAY 



The Anticosti jay was described by Winthrop Sprague Brooks (1920) 

 as a distinct species, but is now to be admitted to our Check-list as a 

 subspecies. Mr. Brooks gives its characters as follows: "Size about as in 

 P. canadensis nigricapillus Ridg. of Labrador. In color this jay differs 

 at a glance from P. canadensis nigricapillus in that the upper parts, in- 

 cluding lesser wing-coverts and upper tail-coverts, are plain slate-color 

 (instead of mouse gray), the black of crown and occiput slate-black
