much louder than any other Woodpecker, and can be heard 

 a long way oft*. 1 found on dissection that it is the female 

 which has the head entirely red. 



9. ClIRYSOFTILUS CRISTA TITS. 



One of the commonest birds to be met with in the woods 

 near Gualeguaychu. 



10. PlCUS CACTORUM. 



This is a very pretty and a very common little bird. It 

 and C. cristatus are more numerous than C. agricola; but all 

 three species arc frequently to be met with, while C. boicei is 

 always scarce. The "capitan" (head man) of one of my friends, 

 on being shown C. boicei, recognized the bird at once as having 

 been seen by him on one occasion only, a year or two pre- 

 viously, when he was struck by the black body and brilliant 

 red crest; but he has never again met with it. 



11 . COLAPTES AGRICOLA. 



This Woodpecker is quite common, and is generally seen 

 in open ground. It is often found hopping about over the 

 grass in little parties of three or four. 



12. Hydropsalis torquata. 



This bird may often be seen in the woods on summer even- 

 ings j but it is difficult to procure a good specimen, as one 

 must get near to distinguish the species, and then the shot 

 often spoil the beautiful tail-feathers. 



13. Nyctidromus albicollis. 



11. podageb nacunda. 



Neither of these is uncommon j and they may be found in 

 much the same localities as Hydropsalis torquata. There is 

 a larger kind of Night-jar which sometimes gets up in flocks 

 oft' the camp when one is riding in the daytime j it has a large 

 white patch on the wings. 



15. BOLBORHYNCIIUS MONACHUS. 



One of the commonest birds in the country. I noticed 

 three kinds of Parrots during my stay, viz. this species, a 

 smaller variety, of a brighter green colour, and a rather 

 larger bird, with an orange and red patch on the breast. The
