 1874, p. 332.) 



M. c. nut'tingi. (To C. C. Nutting.) Nutting's Crested Flycatcher. Like the last, 

 and especially like its young, which have the tail-feathers more e.\tensively rufous than the 

 adults. Outer web of outer tail-feather not distinctly whitish, and its inner web wholly rufous, 

 or with only a narrow dusky stripe, not widening at the tip. Kather small ; wing 3.40-3.70 ; 

 tail 3.35-3.80; tarsus 0.85; bill from nostril 0.50. Arizona, from the vicinity of Prescott 

 southward through western Mexico to Costa Rica. A nest found in a giant cactus June 12, 

 1892, contained 4 fresh eggs 0.95 X 0.67, indistinguishable from those of cinerascens proper.

M. lawren'cei. (To Geo. N. Lawrence.) Lawrence's Crested Flycatcher. Similar 

 in color to M. crinitus, but much smaller, and belonging to a different section of the genus. 

 Bill broad, flat, shaped much as in Contopus, about i its own length wide at the nostrils. No 

 chestnut on tail-feathers except a narrow bordering on outer webs, and, in the young, an inner 

 margining also. Wing-coverts and inner secondaries as well as primaries edged with rufous 

 (rarely yellowish on inner secondaries) ; pileum dark or quite blackish. Very small : length 

 7.00 or less; wing and tail only 3.00-3.40; bill 0.62-0.70 ; tarsus 0.75. Lower Rio Grande 

 valley of Texas through eastern Mexico to Guatemala; only included in our fauna on the 

 authority of Giraud, 1841. It is a long but not yet well known species. 

 M. 1. olivas'cens. (Lat. olivascens, growing olivaceous, somewhat olivaceous.) Olivaceous 

 Crested Flycatcher. Like the last ; lighter colored ; crown little darker than back ; wing- 

 and tail-feathers usually without rufous edging. Wing 2.90-3.25 ; tail 3.00-3.25. Western 

 Mexico, S. to Yucatan, N. to Arizona regularly, casually to Colorado (Fort Lyon, May 11, 

 1883). (M. lawrencei Brewst. Bull. Nutt. Club, 1881, p. 252, Santa Rita Mts. Ariz, in 

 May of that year; first record for the species in the U. S. since 1841.) But the bird is now 

 known as a common summer resident of mountains in Arizona and New Mexico, up to about 

 7,000 feet. Nest in Woodpecker holes and natural cavities in trees, of fur, feathers, and other 

 material; eggs 2-4, with finer markings than usual in this genus, laid in May and June.

SAYOR'XIS. (Name of Thos. Say, with Gr. Spvis, ornis, a bird.) Pewit Flycatchers. 

 The 3 following species do not particularly resemble one another ; most authors place them in 

 separate genera, and some even under different subfamilies, of Tyrannidce. But the discrep- 

 ancies of form are not startling, and for the purposes of this work the species may be properly 

 kept together, as they agree in presenting a certain aspect not shown by other N. Am. groups. 

 (Fig. 344, b.) They are small — about 7.00 or less in length. Head with a slight crest of 

 erectile feathers. Tarsus rather longer than middle toe and claw (the reverse in C. ^orea/i«). 

 Bill narrower than in other little Flycatchers, with nearly straight lateral outlines, its width at 

 base about ^ length of culmen. Wing pointed by 2d-5th quills, 1st shorter than 6th. Tail 

 about as long as wing, emarginate, with broad feathers tending to divaricate in the middle. 

 One eastern, two western species. Nest affixed to rocks and buildings, with mud; eggs white, 

 normally unmarked, but often sparingly dotted with brownish. (Name spelled Sayornis origi- 

 nally by Bonaparte, 1854; A. O. U. Lists, 1886 and 1895; Sai/iornis CouES, Key, 2d-4th 

 eds. 1884-90. Type of genus Tyrannula nigricans Swains. 1827.)
