somewhat varied by dusky, whitish, and buff edges and bases of some of 

 the feathers, the bulf showing most on breast and the dusky and whitisli 

 on center of abdomen; himinous throat patch glittering grass green; 

 partially concealed woolly feathers on center of belly and flanks while ; 

 under tail-coverts ochraceous-bufF with faint green central spots; tail, 

 below, shining auricular purple ; above, in some lights, auricular purple, 

 in others, dark shining grass green. Adult 9) above shining grass 

 green ; below, throat ochraceous-rufous, gradually becoming ochraceous- 

 buff on chest and center of abdomen; sides spotted with shining grass 

 green; under tailcoverts ochraceous-buff with dusky central spots; tail 

 smaller than in the cf, all the outer rectrices tipped with buff. Young 

 (^ similar to adult 9) l>'^t with rather more green on sides; older (j^ 

 similar to adult (^, but lacking the luminous throat patch. 



Measurements. — AAwM (^, No. 6232, from Paramo de Macotama : Wing, 

 60; tail, 44; culmen,12.6; width of central rectrix, lO.S. Adult $ (type) : 

 Wing, 53; tail, 34.4; culmen, 12.4; width of central rectrix, 8.2. 



Remarks. — Strangely enough M. districta bears a much stronger super- 

 ficial resemblance to the far-away M. smaragdiiiicoUis, as pointed out by 

 Messrs. Salvin and Godman and by myself, than it does to its nearest 

 neighbor, M. iyrlantldna, of Venezuela and Colombia. The splendid 

 series secured last winter by Mr. Brown proves, as might be expected, 

 that the slight diflerences l^etween the Sierra Nevada de Santa Marta bird 

 and M. smarugdinicoJUs are perfectly constant.

Remarks. — 0. pernix is wholly different from either 0. fiirnigalns of Co-
