18. PSEUDOLEISTES VIRESCEN8 (Vieilh). 



Breeding in end of November. A typical nest was placed 

 in the thickest and highest part of the clump of thistles above 

 mentioned, about two feet from the ground. It was built of 

 dry grass, then a thick layer of mud, still moist, and was 

 sparsely lined with some fine grass or rootlets. It contained 

 five eggs. 



19. LeISTES SUPERCILIARIS, Bp. 



This species was abundant during all the time of my stay, 

 frequenting the open camp and grass-coverts. Latterly I 

 had strong suspicions of its breeding, but did not succeed in 

 getting a nest. The note is harsh and unmusical. 



20. T^NIOPTERA DOMINICANA (Vicill.). 



A not uncommon bird, and very conspicuous from its 

 plumage, generally to be seen in pairs ; but I found no 



nests. 



21. Alectorurus guiru-yetapa (Vieill.). 



I was much struck by the appearance and habits of this 

 species and the contrast between the male and female. The 

 bare part of the throat in the former is of a reddish colour, 

 not pleasing to the eye. It was not uncommon, frequenting 

 localities where a few trees were associated with high grass, 

 thistles, and isolated plants of a similar height, preferring to 

 alight on the latter. The flight is singularly weak and 

 feeble, not necessarily low, but like the fluttering passage of 

 a butterfly through the air. The tail is not expanded, but 

 floats along behind in a semi-detached way. One nest which 

 I succeeded in obtaining was placed on the ground among 

 some weeds; it was neatly built of grass, lined with the 

 same and a few feathers, and contained three eggs. The 

 date was 21st October. 



22. Machetornis rixosa (Vieill.). 

 Not uncommon. 



23. Hadrura pecturalis (Vieill.). 

 Not rare.
