mayr. It is easily distinguished from this latter form, however, by 

 the much paler, less rufescent shade of the upper parts and flanks, 

 and by the paler gray of the breast. The single San Lorenzo speci- 

 men differs from the rest of the series in the color of the pileum, 

 which is sooty olive instead of russet, and in having the brown of 

 the flanks more restricted, as in H. hilaris bangsi, but in other char- 

 acters it agrees much better with the present fota. This individual 

 is the only one even suggesting intergradation between the two forms, 

 and in the absence of further evidence it seems best to keep them 

 specifically distinct, as Mr. Bangs insists. 



This wren is so similar to H. hilaris bangsi as to be practically in- 

 distinguishable in life. There is a decided difference, however, in 

 their altitudinal distribution, the present form occurring higher up 

 than the other, as a bird of the upper Subtropical and Temperate 

 Zones. On the San Lorenzo it probably does not range much below 

 8,000 feet, for the other species is plentiful there at 7,000 feet. In the 

 Sierra Nevada, however, on account of the relatively lower tempera- 

 ture at corresponding altitudes, it is found as low down as 6,000 feet. 

 It was not noted by the writer above 10,000 feet, although Mr. Brown's 

 specimens were taken on the Paramos de Chiruqua and Macotama, at 

 11,000 to 12,000 feet. It is not a rare bird, but is difficult to secure 

 on account of its habit of keeping near the ground in the most im- 

 penetrable thickets and in dark ravines, especially the latter. The 

 song is very similar to that of H. hilaris bangsi, but is seldom heard, 

 while the other species is constantly whistling, and is moreover very 

 inquisitive.
