a nest placed in the tuft of a palm tree. Anotlier clutch of 

 four eggs taken 27th November 1886 from a nest placed in 

 a hole in a palm tree. 



These eggs average in size 1 ^V hy f ^ inch, the smallest 

 being |^ by -|^, and the largest IfV by |i inch. The first 

 clutch varies greatly in size, while the other is nearly 

 uniform. They are of a delicate pale blue colour, finely 

 streaked with hair-like markings, and a few spots of very 

 dark purple, chiefly round the larger end. 



The nest is formed of the points of the palm leaves and 

 twigs of climbers which run up the palm trees. The former 

 are like flat grasses and are interwoven into a cup-like nest, 

 which measures 4J- inclies across, with an opening of 3 

 inches, and is IJ inches in depth. 



5. Myiarchus tyrannuhis (Mlill.). Tiusty-tailed Tyrant. 

 Local name Guira caballero {Suiriri ijo.rdo y roxo. Azara). — 

 This Tyrant bird is found throughout South America down 

 to the Argentine Eepublic. White found it within the 

 latter in the provinces of Oran and Salta, where, he says, it 

 takes the place of Pitangus bellicosus, and Barrow observed 

 it at Concepcion on the Lower Uruguay. It is rather a 

 solitary and silent bird, often found sitting by the sides of 

 paths through brushwood. 



Clutch of four eggs taken on 7th November 1886 from a 

 nest in a hole in a palm tree. They are oval in shape, 

 nearl}^ uniform in size, averaging -|^ by -f-^- inch, and are of 

 a rich cream colour streaked longitudinally with greyish 

 lilac and dark brown markings. 



The lining of the nest which accompanied the eggs con- 

 sisted of matted hair interspersed with small pieces of the 

 cast skin of a serpent. 



6. Fwnuirius rufiis, Gm. Oven Bird. Local name 

 Hornero {Hornero. Azara). — This fussy bird is as common in 

 Paraguay as in Uruguay, and its nest is of the usual form, 

 from which it derives its name. 



7. Fhacellodomus ruber (Vieill.). Red Thorn Bird. Local 

 name Anumbi {Anicmhi roxo. Azara). — This is a species of 

 very retiring habits like our own hedge sparrow, although 

 not so active in its movements. It is not uncommon, 3'et it
