 streak through eye (running beneath crest, on occiput), and chin (sometimes 

 throat also) velvety black ; anterior portion of malar region white. Young much 

 duller than adult, the lower parts streaked with brownish or dull grayish on a 

 whitish ground. Nest in trees, bulky, constructed of small twigs, rootlets, etc., 

 mixed and lined with feathers and other soft materials. Eggs 3-5, pale dull bluish

618. A. garrulus Linn. Bohemian Waxwing.

The male of tbe single Mexican species (P. cinerens) is uniform plumbeous, becoming ashy on head, which 

 fades to nearly white anteriorly ; flanks bright golden olive, or oil-yellow, the under tail-coverts rich gam- 

 boge-yellow ; eyelids white ; ear-coverts and occiput (beneath crest) soft grayish brown. The female is grayish 

 brown where the male is plumbeous, the flanks wholly light brown, the wings and tail duller black, white spots 

 on inner webs of tail-feathers more restricted, etc. An allied Guatemalan race {P. cvnereus molyhdophanes, 

 new subspecies) differs in having the plumbeous decidedly deeper, the flanks olive-green instead of oil-yellow, 

 etc. The dimensions are nearly the same (length about 7.75-8,00, wing 3.70, tail 4.00-4.25). A very fine 

 Costa Rican species (P. candatus Cab.), with long and much graduated tail but very similar plumage, is the 

 type of the subgenus Sphenotelus Baird (Rev. Am. B. i. May, 1866, 412).
