(No. 36,988, % ?) Bill shorter than the head ; gonys slightly convex. Color 

 of upper parts, with sides of neck, ash-gray ; the middle of back, and less 

 conspicuously, the upper tail coverts, streaked with black. A line from' 

 nostrils to above the eye (passing into white for a short distance behind it),
