170 Mr. H. Durnford on the Birds of 
13. Atticora cyanoleuca (Vieill.); Scl. et Salv. P. Z. S. 
1869, p. 159. 
Arrives at the end of September, and generally leaves in 
March; but this year I observed two, a little north of Buenos 
Ayres, on the 30th of April. This, the smallest species of 
Hirnndinidse, always reminds me of the Sand-Martin at home. 
In its habit of flying close to the ground and frequenting the 
neighbourhood of pools and streams, from which it never 
wanders far, it is essentially like that bird. It nests in holes 
in the banks of arroyos, sandpits, and similar localities. 
14. Stephanophorus leucocephaltjs (Vieill.); Scl. et Salv. 
P.Z. S. 1869, p. 161. 
Common in winter in flocks, frequenting bushes and low 
trees; but I have not observed it to the south of Buenos 
Ayres. Its food consists of buds and young shoots. From 
its handsome crimson crest-feathers, and delicate grey and 
pale blue plumage which flanks these, it is one of the most 
beautiful birds we have. Iris wood-brown; beak blue-black, 
under mandible slightly the lightest; legs and feet brown- 
black. 
15. Tanagra striata (Gm.) ; Scl. et Salv. P. Z. S. 1868, 
p. 139. 
I have only observed this Tanager here two or three times. 
In February I shot a young bird at Punta Lara, which must 
have been bred there; and in June and July last I saw several 
birds, both males and females, about thirty miles to the north 
of Buenos Ayres. They seem fond of low damp ground where 
there are plenty of reeds. 
16. Guiraca glaucocvERulea (Lafr. et D'Orb.); Scl. et Salv. 
P. Z. S. 1868, p. 139. 
A summer visitor, but rare. I have only seen it once, when 
I met with it in the riverain wood at Punta Lara. 
17. Spermophila ornata (Licht.); Scl. et Salv. P. Z. S. 
1869, p. 632. 
A spring and summer visitor, arriving about the end of 
October and leaving again towards the end of April; during
