We have been led into a more detailed description of this 

 bird than we usually give to an already described species, ui 

 order to point out the differences of its characters from those of 

 our European Hir. rustica, with which it has been generally 

 confounded. The chief distinction is in its inferior size ; in the 

 side-feathers of the tail being shorter, and at the same time less 

 gracile ; in the frontal band being wider, and in the ferruginous 

 colour extending over the breast, in place of the broad black 

 band which characterizes the European species. Our New Hol- 

 land specimens accord accurately with the figures and descrip- 

 tions of this species given by MM. Sparmann and Temminck 

 from Javanese specimens. The migratory habits of these birds 

 account for their wide dispersion. 



In Mr. Caley's MSS. we find the following observations on 

 these birds. " The resting-places of these Szivallou's are on the 

 dead boughs of large trees, where I have seen several of them 

 gathered together, in the same manner as European Szcallozcs, on 

 the roof of a house. I apprehend, however, that it is when their 

 young have taken to flight that this occurs."
