A. cozumclce similis et cauda ejusdem coloris ; corpore subtus quoque griseo, uropygio tamen multo magis pallide 

 cinnamomeo. (Descr. exempl. ex Tizimin, Mexico. Mus. nostr.)

 (G. F. Gaumer). 



This form is closely allied to A. cozumelce, 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 cozumelEe.

A. dtreopygio similis, sed supra paUidior : subtus grisescentior ; cauda brunnescente ad basin vix cinnamomea, 

 uropygio saturate cinnamomeo. (Descr. exempl. ex Cozumel I. Mus. nostr.) 



Hab. Mexico, Cozumel I. {Benedict ^ 2, Beirs *, G. F. Gaumer ^). 



This form appears to be restricted to the island of Cozumel. It may be distinguished 

 from A. dtreopygius 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.

A. dtreopygio similis, sed undique multo magis virescens ; dorso medio palHore cinnamomeo-brunneo ; cauda 



pauUo obscuriore ; uropygio multo flavescentiore. (Descr. maris ex San Pablo, Panama. Mus. nostr.) 

 Femina mari similis. 



Hab. NicAEAGUA, Los Sabalos {Nutting '') ; Costa Eica, Guaitil (Carmio? ^), lxdiZ-a.{Rogers), 

 Tucurriqui {Arce) ; Panama, Volcan de Chiriqui ^, Calovevora ^ {Arc6), Lion Hill 

 {M'Leannan^^), San Pablo {0. S.^). — South Ameeica, 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. dtreopygius is obvious when 

 the more typical specimens are compared ; but Costa Eican examples sometimes have 

 the base of the tail more rufous, so that the line of distinction becomes obscured.
