The two Guanacaste specimens while dark, as is typical of guat- 
malensis, are slightly grayer, less brownish above than the average 
from eastern Costa Rica, Nicaragua, and Honduras. 
MYIARCHUS CRINITUS CRINITUS (Linnaeus): Southern Crested Flycatcher 
Turdus crinitus LINNAEUS, Systema naturae, ed. 10, vol. 1, 1758, p. 170 (South 
Carolina). 
Three of the crested flycatchers taken at Liberia are representative 
of the southern form, with larger bill and darker dorsal coloration. 
On October 23 I shot one from an open tree at the edge of a pasture 
near the Rio Colorado. On October 26 and November 2 others were 
obtained near Liberia in bushy fields and at the border of woodland. 
MYIARCHUS CRINITUS BOREUS Bangs: Northern Crested Flycatcher 
Myiarchus crinitus boreus BANas, Auk, Apr. 1898, p. 179 (Scituate, Mass.). 
On November 3 I secured a male in woods along the Rio Liberia 
below Liberia. Apparently this race comes regularly to Guanacaste, 
as we have another taken by Underwood at Bebedero on February 12, 
1890. 
MYIARCHUS NUTTINGI NUTTINGI Ridgway 
Myiarchus nuttingi Ripaway, Proc. U.S. Nat. Mus., vol. 5, Sept. 16, 1882, p. 394 
(La Palma de Nicoya, Costa Rica). 
Near Liberia I secured specimens of Nutting’s flycatcher on Oltober 
28, 29, and 31 and November 2, finding them in brushy areas. They 
seemed to be common and were quite noisy. In life they appeared 
identical in most instances with Myiarchus tyrannulus brachyurus, 
which ranged with them, and in the short space of time of my field 
work I was never certain of them until I had them in the hand, 
though with greater familiarity it is probable that the two could be 
distinguished in life in most instances. The smaller bulk of the present 
bird, with the wing measuring under 90 mm., serves to distinguish it, 
as does the decidedly smaller bill when compared with brachyurus. 
MYIARCHUS TYRANNULUS BRACHYURUS Ridgway 
Myiarchus brachyurus Ripgway, Manual of North American birds, Sept. 1887, 
p. 3384 (Ometepe, Nicaragua). 
Near Liberia these flycatchers were common, and between October 
23 and November 17 I secured nine specimens. On November 9 
I shot one in the coffee plantation near the house at Hacienda Santa 
Maria. They were found in open woods and in the brushy borders 
of heavy forest and were active and noisy. 
Van Rossem * has found intergradation between this form and 
Myiarchus tyrannulus nelsoni in El Salvador, which affords satis- 
factory allocation of a bird whose previous status has been a little 
uncertain. He records it as confined to mangrove swamps in the 
14 Publ. Field Mus. Nat. Hist., zool. ser., vol. 23, 1938, pp. 367-368.
