the Alexandra District, S. Austraha. 413 
colour. The rump is noticeably lighter than the rest of 
the back, which is not the case in the typical P. sonora. 
Owing to the faintness of the striations on the breast and 
flanks, the under parts are not so dusky; the abdomen and 
under tail-coverts are unmarked, being of a dirty white 
colour, washed with isabelline. Total length about 7 inches, 
culmen ‘8, wing 3°6, tail 3°7, tarsus 1. 
In the large series of P. sonora at the British Museum 
there is a single skin from the late Mr. Gould’s collection 
agreeing fairly well with the two birds from Alexandra. 
The label unfortunately gives no locality other than “ Aus- 
tralia”’; it bears the MS. note “light variety,” shewing that 
Mr. Gould did not consider the specimen as typical.

The measurements of one of the skins (no. 33) slightly

apy of the examples in the National Collection. The food 
consists of insects.
