Notes from South Brazil. 13 



also by Euler), as is evident from the note on the yellowish 

 colour of its lower mandible. 



The number of species of birds of the interior of Rio 

 de Janiero is raised by this addition to 385. It would be 

 useful if European ornithologists would co-operate with me 

 in completing these lists of the local faunas of Rio de 

 Janeiro, S.Paulo, and Rio Grande do Sul, which I have thus 

 attempted to set in order. 



My ' Catalogo critico-comparativo dos Ninhos e Ovos das 

 Aves do Brasil,^ published in the same volume of the ' Revista ' 

 (pp. 191-300), is a synopsis of all that is yet known of the 

 nidification and eggs of Brazilian birds. This is, in truth, a 

 very difficult subject to deal with satisfactorily. All those 

 who have taken up collecting-work in this country have been 

 misled by the native assistants' practice of attributing eggs to 

 birds to which they have no relation whatever. Thus the 

 literature of this subject is full of wrong descriptions and 

 mistakes. For example, such an egg as that of Ammodromus 

 manimbe (Sbarpe, Cat. B. xii. p. 691) has been described 

 several times, but always wrongly. It is evident that much 

 further work and study, based upon special knowledge, is 

 required to separate the good observations from the doubtful. 



The above-mentioned paper is, however, not altogether a 

 compilation, for many new observations are added to what 

 was previously known. Among these may be especially 

 noticed the very singular suspended nest of Thripophaga 

 sclateri with two chambers [op. cit. p. 246, figs. 20, 21). 



Since I published the paper, I have obtained some new 

 eggs from S. Lourenco, Rio Grande do Sul. These may 

 be described as follows : — 



Ceophlceus erythrops (Val.). 



The eggs are thin and transparent, of a uniform bluish- 

 white colour, polished, and lustrous. The measurements 

 are 30-31x24-25 mm. 



Chrysotis vinacea (Vieill.). 



This is an egg of 38 x 30 mm. in dimensions and of oval 

 form. The poles are subequal, the surface is smooth, little
