30. Chrysomitris uropygialis Sclater. 



This bird lives in cultivated places, on meadows, and near 

 water. It is not common ; it feeds on seeds. It was 

 observed at Moreno up to an altitude of at least 4G00 metres 

 above the sea-level. 



31. Pseudochloris lutea (d'Orb. et Lafr.). 



This bird is usually seen singly along the rivulets at 

 Moreno, where it is common. It feeds on seeds and buds. 



32. ZONOTRICHIA CANICAPILLA Gould. 



Iris yellowish brown. Very common at Moreno, feeding 

 on seeds and insects ; it builds its nest in stone Avails and 

 under the roofs of houses. 



The specimens from Moreno are to a certain extent inter- 

 mediate between Z. pileata and Z. canicapilla, having the 

 coloration of the former and especially the black bands on the 

 sides of the crown ; but they are much larger than Z. pileata^ 

 almost attaining the size of Z. canicapilla, and I therefore 

 refer them to that species. Wing 80, tail 75, culmen ] 3 mm. 



Schalow (Fauna Chilensis, Bd. i. Zool. Jahrb. Suppl. 

 p. 723) regards Z. canicapilla as a subspecies of Z. pileata. 



33. Phrygilus fruticeti (KittL). 



Rather scarce, feeds on seeds and buds. Two specimens 

 were shot at Moreno in November, 1901. It has been 

 reported by Dr. Sclater from Peru, at an altitude of 

 14,000 feet {cf. P. Z. S. 1881, p. 486). 



34. Phrygilus atriceps (d'Orb. et Lafr.). 



Iris yellowish brown. This bird was common in the 

 Pampas-grass {Gyneriurri) along the rivulets at Moreno. 

 Its food consisted of seeds and buds. It builds its nest 

 in tufts of Pampas-grass. One which Mr. von Hofc'sten 

 brought to me was taken on December 20th, 1901, and was 

 constructed of grasses and pieces of dry herbs, lined with 

 horse-hair and the wool of the vicuna. It contained three 

 eggs, bluish green in colour, with numerous small pule 

 brown spots and blotches scattered all over the surface, most 

 densely at the greatest circumference and least at the ends. 

 The longitudinal diameter of the eggs was 21-25 mm., the 

 greatest transverse 17 mm.
