Myrmelastes immaculatus berlepschi Ridgw. — 2 (^(^, 1 $ 

 ^4, Santo Domingo de los Colorados, road to Mana vi, 3000 f.; 

 1 J Vt, 1 (^ 7;, 1 S 7io, below Gualea, 4000 f. »Always found 

 beside the large anthills, feeds on the ants and their eggs. 

 Local name: »hormiguero ». (L. S.) 



Grallaria rufula Lafr. — 8 specimens, Jan. — April and 

 Sept.— Oct. from Pichincha, 11600—12000 f.; 1 S, above 

 Nono, 11500 f. These specimens are all of them much brighter 

 below than above and belong consequently to the typical form, 

 not to the dark G. r. saturata Domaniewski & Stolzmann. 



Grallaricula costaricensis Lawti. — 2 <^(^, 1 $ collected in 

 March and May at Mindo 5500 f. These specimens agree 

 completely with Ridgway's description of Costa Rica speci- 

 mens, and Chapman has also recorded the same species from 

 Central Colombia. The brown maxilla of our specimens proves, 

 that they have nothing to do with G. flavirostris Sclater 

 from Eastern Ecuador, and this is thus still another example 

 of greater affinity between the birds of Western Ecuador 

 and those of Central America than with those of Eastern 

 Ecuador. We are also able to confirm Chapman's statement 

 about the variability of the species as one of the males in 

 the present collection has the ochraceous buff more broadly 

 extended över the breast and flanks and at the same time 

 much more vi vid than in the other. As the specimens are 

 from the same locality this must be purely individual. 



Upucerthia excelsior Sclater. — "^ (^<^, 2 $$ collected at 

 various times of the year, Pichincha, 13000 f.; 1 $ ^Vi2 below 

 Guamani W. of Papallacta, 13000 f. 



Cinclodes juscus albidiventris Sclater. — 1 $ ^/^, 1 o Vs' 

 1 c^, 1 ? 'y„ 1 ^ Vi„ Pichincha, 13500—14000 feet (below 

 crater). 



Leptasthenura andicola Sclater. — 6 c^(^ & 4 $$, Pichin- 

 cha, 13 — 1400 f. »From 11000 feet up to near the crater of 

 Pichincha.» (L. S.) 



Synallaxis hrunneicaudalis Sclater. — 2 J(^ & 1 ?, July, 

 Mindo, 5500—7000 f.; \ ^ 'V^, Nono, 8000 f. Although this 

 species originally was described from Napo, thus from the 

 eastern side of the Andes, we cannot from the descriptions 

 find out any aberrance in these specimens.
