Genus ELACHURA Gates, 1889.

This genus was created by Gates for the little Wren Troglodytes formosus (punctatus), which differs from the typical birds of the genus Troglodytes in having a much stouter bill and a more graduated tail. The plumage in Elacliura is spotted and not barred. In Elacliura the sexes are alike and the young are probably similar to the atkilt. The bill is stout and almost half the lengtl'i of the head. The wing is very short and rounded and the first primary is about two-thirds the length of the second. The tail is. well graduated, the outer feathers reaching to about the middle of the central ones. The tarsi, toes and claws are long and strong. There are only two species known and one of these, Elacliura liaplonota, is represented by a single specimen. Key to Species. A. Upper plumage spotted, Elacliura formosa,* p. 449. B. Upper plumage unspotted Elachura haphnota^ p. 450. punctatus is already preoccupied by Brebni. Troglodytes for jiiosus of Waldeii is therefore the next available.
 * The name punctata cannot be used for this little Wren as Troglodytes
