378 Mr. E. Gibson on the Ornithology of [Ibis, 



The breeding-season is in the first half of November, to 

 judge from the very sparse number of nests (only four) which 

 I have obtained. Two of these were in Tala trees^ one in a 

 cleft and the other at the very extremity of a brancii, to 

 which it was attached like a cup to its liandle ; tlie other 

 two liidden in thorny " Brusquilla " bushes : all four about 

 six feet from the ground. The localities chosen were sunny, 

 and in the most retired parts of the woods. Beautifully 

 built of lichens, moss, and spider-webs — lined with horse- 

 hair, small feathers and down, and rather cup-sliaped — the 

 nests much resemble those of the Chaffinch. The respective 

 clutches of the four nests were two, three, three, and six — 

 the last clutch of six being laid between 2 and 9 November. 

 The colour of the eggs is a pale yellowish buff, and they 

 are rather roundish. Measurements: 16 X 13 mm. 



12. Troglodytes furvus (Gra.). Brown House- Wren. 

 I have absolutely nothing to add to the notes in my 

 former paper. 



15. Anthus correndera Vieill. Cachila Pipit. 



Until the advent of Mr. Claude H. B. Grant in 1908, I 

 had failed to separate this species from the following one 

 (^A. furcatus). Accordingly, all my former Correndera 

 field-notes are valueless. Mr. Grant himself, however, 

 has omitted to describe the eggs of both birds [vide Ibis, 

 1911, p. 87), so I herewith supplement his notes, from 

 clutches of his own collecting. 



A. correndera. The shape is not so elongated as would 

 be inferred from Hudson, though perhaps more so than 

 those of A. furcatus. Ground-colour a very dirty white, 

 thickly spotted with dusky brown and drab. "In some eggs 

 the spots are confluent,'' as Hudson says, " the whole shell 

 being of a dull brownish-drab colour." To which may be 

 added a tendency to form a ring at the blunt end. According 

 to botii Hudson and Grant, the full clutch is four. Measure- 

 ments : Average 20 X 15 mm,
