Borneo; Corydon (1 species), Malacca, Sumatra and Borneo

The Dendrocolaptidse, or American Creepers, are curious 
brown-coloured birds with more or less rigid tail feathers, strictly 
confined to the continental Neotropical region, and very numerous 
in its south-temperate extremity. They are divided by Messrs. 
Sclater and Salvin into five sub-families, to which I shall con- 
fine my remarks on their distribution. The details of the 
numerous genera, being only interesting to specialists, will be 
given in the table of genera of the Neotropical region. No less 
than 13 of the genera are confined to South-Temperate America 
and the High Andes ; 14 are restricted to Tropical South America, 
while not one is peculiar to Tropical North America, and only 15 
of the 43 genera extend into that sub-region, showing that this 
is one of the pre-eminently South American groups. 
Sub-family I. FURNARiiNiE (8 genera, 30 species). Kanges over 
all South America, 4 genera and 18 species being restricted to the 
temperate sub-region; one species is found in the Falkland Islands. 
Sub-family II. Sclerurdle (1 genus, 6 species). Brazil to 
Guiana, Columbia, and north to Mexico. 
Sub-family III. Synallaxinjs (12 genera, 78 species). Ranges 
from Patagonia to Mexico ; 7 genera and 28 species are confined
