2. Attila gaumeri. . 
Attila citreopygius, Boucard, P. Z.S. 1883, p. 149 (nec Bp.) *. 
A. cozumele similis et cauda ejusdem coloris ; corpore subtus quoque griseo, uropygio tamen multo magis pallide 
cinnamomeo. (Descr. exempl. ex Tizimin, Mexico. Mus. nostr.) 
Hab. Mexico, Tizimin1, Peto in Northern Yucatan, Meco,.Holbox, and Mugeres Is. 
(G. F. Gaumer). 
This form is closely allied to A. cozumele, but appears always to have a much paler 
rump, though the colour of the under surface is nearly the same in both forms. Its 
range appears to be confined to the northern portion of Yucatan and the islands 
off the coast north of Cozumel. 
3. Attila cozumele. . 
Attila cozumele, Ridgw. Pr. Biol. Soc. Wash. iii. p. 281; Pr. U. S. Nat. Mus. viii. p. 5727; Salv.

A, citreopygio similis, sed supra pallidior : subtus grisescentior ; cauda brunnescente ad basin vix cinnamomea, 
uropygio saturate cinnamomeo. (Descr. exempl. ex Cozumel I. Mus. nostr.) 
Hab. Mexico, Cozumel I. (Benedict }*, Deirs4, G. F. Gawmer®). 
This form appears to be restricted to the island of Cozumel. It may be distinguished 
from A. citreopygius by its greyer throat and breast, the latter seldom showing a trace 
of greenish yellow; the rump is of a darker cinnamon, and the tail much browner. 
4. Attila sclateri.

A, citreopygio similis, sed undique multo magis virescens; dorso medio palliore cinnamomeo-brunneo; cauda 
paullo obscuriore ; uropygio multo flavescentiore. (Descr. maris ex San Pablo, Panama. Mus. nostr.) 
Femina mari similis. 
Hab. Nicaraaua, Los Sabalos (Nutting 7); Costa Rica, Guaitil (Carmiol 2), Irazu (Rogers), 
Tucurriqui (Arcé) ; Panama, Volcan de Chiriqui °, Calovevora > (Arcé), Lion Hill 
(M‘Leannan+?), San Pablo (0. S.4).—Sourn Amznrica, Eastern Ecuador. 
This is another of the brown-tailed group, differing, however, from the preceding in 
having the under surface from the throat to the abdomen yellowish green, with dark 
central streaks to the feathers. Its distinctness from A. citreopygius is obvious when 
the more typical specimens are compared; but Costa Rican examples sometimes have 
the base of the tail more rufous, so that the line of distinction becomes obscured.
