A History of North American Birds, Land Birds. Volume 1. Robert Ridgway

this genus but one species is so far known in the United States, the Rock Wren of the earlier ornithologists. It is peculiar among its cognate genera by having the two continuous plates on each side the tarsus divided into seven or more smaller plates, with a naked interval between them and the anterior scutellæ. Other characters will be found detailed in the Review of American Birds, p. 109.
