Habits. Walton records (Ibis, 1906, p. 74) that he shot several

there during very cold weather, when all the streams were frozen 
hard, except one that was supplied by a clear warm spring.” 
Genus ELACHURA Oates, 1889. 
This genus was created by Oates for the little Wren Zvroglodytes 
formosus ( punctatus), which differs from the typical birds of the 
genus Z'roglodytes in’ having a much stouter bill and a more 
graduated tail, The plumage in Elachura is spotted and not 
barred. 
In Llachura the sexes are alike and the young are probably 
similar to the adult. The bill is stout and almost half the length 
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, 
Elachura haplonota, is represented by a single specimen. 
Key to Species. 
A. Upper plumage spotted.............. Elachura formosa,* p. 449. 
B. Upper plumage unspotted............ Elachura haplonota, p. 450. 
* The name punctata cannot be used for this little Wren as Troglodytes 
punctatus is already preoccupied by Brehm. Troglodytes formosus of Walden 
is therefore the next available.
