of Paisandti, Uruguay. 277 



riensis) I found the majority of the following species of 

 birds. 



1. TuRDUs RUFivENTRis, Vieill. 



Only seen in one locality, the woods in the valley of the 

 Cangiie river, a tributary of the Uruguay, about ten miles 

 below Paisandu. 



2. MiMUs CALANDRtA (d^Orb. et Lafr.). 

 Very abundant. 



3. Anthus correndera (Vieill.). 



4. Progne chalybea (Gm.). 



Very abundant, appearing first on 15th September, and 

 breeding about the middle of November. 



5. Progne tapera (Linn.). 

 Appeared on 29th September. 



6. Petrochelidon pyrrhonota (Vieill.). 



Found a nest in a wall of outbuildings 18th November, 

 containing young and an addled egg. 



7. Spermophila hypoxantha (Cab.). 



One shot in pasture near head station lltli November. 



8. DoNACospizA albifrons (Vieill.). 



Is probably abundant, but difficult to distinguish from 

 other grass-covert frequenting species. A female was shot 

 off the nest in grass-pasture near head station 28tli October. 

 It had no note. The nest was placed in the top of a thick 

 clump of grass, and was built of dry grass and fine hair-like 

 roots, and lined with the latter. Number of eggs three. 



9. PoospizA NiGRORUFA (d'Orb. et Lafr.). 

 Appeared ( (;J ) on 1st October. 



10. DiUCA MINOR, Bp. 



Not uncommon. I generally observed it in pairs, fre- 

 quenting the small scattered trees in the open, and each pair 

 very local in its habits. The note is very sweet, aud so ex- 

 ceedingly like that of Paroaria cucullata, that I was never 

 able to distinguish them during the M'hole of my stay.
