which were very similar to those of MilvzihiS tyrannus., but 

 leather smaller. 



74. Milvulus tyrannus {Limi). Tijerita (Little Scis- 

 sors, in allusion to the tail). — By far the most abundant Fly- 

 catcher \vhich breeds at Concepcion. Arriving early in October, 

 it breeds during November and December, and leaves for the 

 north again before April i . It was met with at Azul on Jan- 

 uary 31, 1881, and a single one was seen at Bahia Blanca 

 February 9. 



75- Pachyrhamphus, sp. incog. — Three males of a beau- 

 tiful species probably belonging to this genus were taken at 

 Concepcion during November, 1880. They were shy and silent, 

 moving leisurely from one low tree to another along the borders 

 of the streams. 



76. Phytotoma rutila Vieill. — An abundant bird among 

 shrubbery everywhere, especially in winter. Gravelly localities 

 where the mimosas and other thorny shrubs alternate with the 

 melon and prickly-pear cactuses and where there are occasional 

 patches of brambles and creeping vines overrunning all, are 

 favorite resorts. Here the brick-red breast of the male is a rather 

 conspicuous object as he sits on the top of some low bush utter- 

 ing from time to time that characteristic note which has been 

 well likened by Hudson to the bleat of a new-born lamb. The 

 nest, which may be found late in September or early in October, 

 is quite frail and is commonly well hidden in the green interior 

 of a prickly bush, or a mass of twining vines. It is built mostly 

 of fine twigs and finer roodets and in it the bird deposits usually 

 three bluish-green eggs with brownish flecks. The birds feed 

 largely on green leaves of various kinds with perhaps some 

 bei-ries and a few insects. 



77. Geositta cunicularia ( Fze///.). -^Hardly more than 

 a winter visitor at Concepcion, though a pair seen October 26 

 appeared to have eggs or young. In winter, however, it is very 

 abundant and may be seen running about singly or in pairs on 

 dry, grassy or gravelly places. It is strictly terrestrial and when 

 running about singly it may be driven before one like a chicken. 

 It has a rolling call similar to that of the Downy Woodpecker 

 {Picits pubescens) but weaker, and a nervous way of flirting its 

 wings and raising and dropping the tail which is common to 

 many other birds of this group. It was abundant at Bahia
