The excellent series of 16 skins from Coiba agrees so closely with 
the race that I have named earlier from the Pearl Islands in the Gulf 
of Panama that they must be identified under that name. The Coiba 
birds, when compared in series with birds from Isla San José, Isla 
Pedro Gonzalez, and Isla El Rey in the Archipiélago de las Perlas, 
average slightly darker but not sufficiently so to warrant their separa- 
tion. It is interesting, however, to observe that this heavier pigmenta- 
tion, when compared with the race of the adjacent mainland Elaenia 
flavogaster pallididorsalis, follows the pattern of darker coloration 
that marks other resident forms found on Coiba. 
MYIOPAGIS VIRIDICATA ACCOLA Bangs: Orange-crested Elaenia, 
Mofiona Copete-anaranjada 
Myiopagis placens accola BANGS, Proc. New England Zool. Club, vol. 3, Jan. 30, 
1902, p. 35. (Boquete, Chiriqui.) 
This is primarily a forest species, found from the lower under- 
growth to the intermediate branches of the higher trees, though I 
saw it occasionally in the platano plantations, in more open localities 
along the forest trails, and in fruiting trees with other small birds. It 
moves methodically among the smaller twigs, usually alone, and is 
often overlooked because its greenish and yellowish colors are not at 
all conspicuous in the subdued light of its forest haunts. There is 
seldom any hint of the brilliant orange of the crest until the bird is 
in the hand. It was fairly common. 
The 12 skins taken on Coiba agree in color with birds from 
Chiriqui. . 
SUBLEGATUS ARENARUM ARENARUM (Salvin): Scrub Flycatcher, 
Mofiona Ceniza 
Elainea arenarum Satvin, Proc. Zool. Soc. London, August 1863, p. 190. 
(Puntarenas, Costa Rica.) 
These flycatchers were found in scrub growth back of the beaches, 
and in the border of mangroves, never in the densely shaded high 
forest. They were encountered alone, resting on leafy twigs, or 
occasionally feeding in fruiting trees with other birds. They moved 
quietly among the thickets, flying across small openings with undulat- 
ing flight, and were silent. Though not timid it was difficult to see 
them because of their subdued colors. 
The over-all similarity in color in this species throughout its ex- 
tensive range makes careful study necessary to determine the geo- 
graphic races. Twelve years ago, when I was studying collections
