wing coverts, light king's yellow, changing to olivaceous on the 

 flanks. 



3rd primary rather longest ; 2nd and 3rd subequal. In some 

 cases the 2nd is a little shorter than 3rd, and 1st than 2nd. The 

 female resembles the male in every respect, except that the plu- 

 mage is duller. Length 5 inches ; expanse 8^ inches. 



S. BlacJchurnm. Blackburn's Warbler. 

 Dendroica BlacJchurnice. Baird ! 



V.S.P. Bill, tarsi, toes, and claws black ; irides black ; eggs 

 unknown. 



Dorsal aspect. Crown of head and nape of neck black, the 

 former intersected by a stripe of bright orange, and bounded as 

 well as the latter by a stripe of the same colour, which com- 

 mences at the nostrils and passes over the eye ; dorsal region 

 black, interspersed with a few streaks of brownish -white ; tail co- 

 verts black, margined with brownish white ; tail square, black. 

 The inner vanes of nearly all the lateral feathers white except to- 

 wards the tips ; outer vanes margined with brownish-white ; small 

 wing coverts black ; greater ones black with white tips to the 

 outer vanes ; coverts of the secondaries or scapulars all white. 

 Brownish-white margins on the outer vanes of the quill feathers. 



Ventral aspect. An orange spot below the eye; auriculars 

 black, bounded by orange ; chin and throat bright orange, bound-

 flanks ; breast yellow, dull, fading to white on vent and tail fea- 

 thers, numerously interspersed with black streaks except in the 

 two last positions. 



1st primary longest, then the 2nd, and then the 3rd. Length 

 4J inches ; alar expanse 8 inches. According to Nuttall the 

 three lateral feathers only have white on their inner webs. In the 

 specimens which I have seen, some five or six, it existed on the 

 inner vanes of all except the two central feathers. This bird is 

 one of the most pretty of the Sylvian genus. On the Island 

 of Montreal it is not plentiful, but is found much more numerous- 

 ly in the groves of St. Remi on the south side of the river.
