This is a purely Neotropical genus containing, according to Mr. Hargitt, seventeen 
species, which are spread over the greater part of the region from its most northern 
boundary in Mexico to Paraguay and Argentina. Six species are found within our 
limits, all of them peculiar, except C. yucatanensis, which ranges into the north-western 
parts of the southern continent. Of the other species, three are restricted to Mexico 
and two to Costa Rica and Panama. | 
The bill is curved, with a distinct ridge on each side of the culmen; the tarsus is less 
than the outer reversed toe and its claw; the wing moderately long; the tail rather 
short, the short outer rectrix reaching nearly to the tips of the longest coverts.

The Eastern Cordillera of Tamaulipas, and thence southwards through the whole of 
the central and northern portion of the State of Vera Cruz on the flanks of the 
mountains sloping towards the Atlantic Ocean und onwards to the State of Oaxaca, 
is the home of this Woodpecker, where it ranges from the sea-level to as high as 
5000 feet in the mountains. It appears to be strictly confined to this region, for 
immediately to the southwards, in Southern Vera Cruz, in the State of Tabasco, and in
