TEOQLODTTES, 101 



and southwards of Costa Eica the Andean race of T. furvus appears. From both of 

 these T. intermedius differs in its rufous-brown colour, though in this respect it 

 approaches the Brazilian form of T. furvus, the tail, however, being shorter and the 

 crissum more strongly banded. 



After being for some time doubtfully referred to T. aedon ^, or left unnamed ^, it was 

 described from Costa-Eica specimens as T. intermedius ^ by Dr. Cabanis, and the follow- 

 ing year as T. hypaedon by Mr. Sclater'' from Mexican and Guatemalan examples. 

 Subsequently Prof Baird compared Mexican and Costa-Eican birds, and pronouncing 

 them to agree in general appearance, placed both under Dr. Cabanis's name ^. 



In Guatemala T. intermedius is a very familiar species, being found in villages and 

 towns throughout the country irrespective of elevation, as we observed it at various 

 places from 8000 feet to the sea-level. Its favourite resort is the thatch or tiled roofs 

 of houses, where it lives a restless life in pursuit of food. Its song is lively, but short, 

 and of no great power or compass. It frequently utters a kind of scolding note, which 

 has doubtless gained for it the name of " Curuchichi," which not inaptly expresses it. 

 ' A nest found at Buenaventura, on the Lake of Panajachel, was in a hole in a bank, the 

 eggs being exactly like those of T. aedon, pinkish white, thickly freckled with red spots.
