rior pair; remaining feathers tipped with liair brown. liroad super- 

 ciliary stripe white; lores and cheeks white, somewhat mingled with 

 brownish; postocnlar streak like the crown; sides of neck brownish 

 gray; chin and throat pure white; rest of lower surface grayish wliite; 

 sides and flanks tinged with brownish graj', this color deepest and 

 most brownish on the latter; crissum tinged with ochraceoiis, atid

Youmj in frst plumage. — Male; No. 308, Coll. .1. Orinnell; San Ole- 

 mente Island, ('alifornia, June 2, 1807; J. (Irinnell. Upper parts, 

 including middle lectrices and ])roximal portion of outer webs of all 

 but exterior i>air, brownish gray, slightly paler on the rump, the 

 feathers of which have hidden sjmts of dull white; tail barred with 

 black; remainder of tail black, tii)i)ed with slate gray, the two outer 

 pairs of feathers barred distally on external webs with dull white. 

 Edges of greater wing coverts slightly rufescent, outer margins of 

 prinniries bufty; secondaries and greater coverts obsoletely barred 

 with dark biown. Superciliary stripe white; lores and cheeks grayish 

 white, mixed with brown; postocnlar streak dark brown; lower parts 

 brownish white; throat, breast, and sides thickly mottled with dusky, 

 this light and dark niaiking invading the sides of the neck; sides .ind 

 thinks ])a]e brownish gray, more rufescent on the latter; crissum 

 washed w ith ochraceous and barred with blackish. 



The cliaracters which separate T. h. JeKcophri/s from clifinaiinnis 

 consist in the rather i)aler, grayer thinks and ui)per paits, the longer bill, 

 and less heavily barred inferior tail-coverts. Compared with nesophiius. 

 leucopJirys is readilj'^ distinguishable by its mu(;h i)aler and grayer 

 (;oloration, less heavily barred crissum, longer bill, somewhat longer 

 wings and tail. The interior form, eremophilus, ai)i)roaches very close 

 to leKcophri/s in color above, though averaging rather more rufescent, 

 at least in winter, but differs in its narrow superciliary stripe, paler 

 Hanks, decidedly longer wings and tail, shorter bill and tarsus. 



The examination of good series of leucoplirys and charicntnriis shows 

 that no one of the characters which serve to separate these forms is 

 entirely constant. Some sj^ecimens of Iriic(>phri/,s are quite as conspic- 

 uously barred on the crissum as is (haricniurun; gray exami)les of the 

 latter almost exactly match the darker ones of leucophri/s; while the 

 broad su])erciliarv stripe, a character em])liasized by Mr. Anthony in 

 the name leucoplirt/s, is one common to apparently all the Pacilic coast 

 forms, though it is due to say that the type of leucophrys presents in 

 this respect a rather exaggerated phase, a difference not borne out by 

 the other specimens from San Clemente Island, even after proi)er allow- 

 ance has been made for iedu(!tion in width by natural abrasion. In 

 view of these fa(^ts it seems nnadvisable longer to accord leucophrys 

 more than subspecilic rank. 



The type is a bird m fresh fall ]>lnmage, and seems to be noticeably 

 more rufescent above than any of the other specimens in similar cou-
