MANGROVE ROBIN. 
and are mostly seen perched on a twig close to the ground. They sit perfectly 
still, occasionally uttering a low whistling note, which is repeated once. They 
will come within a few feet if one remains quite still for a few moments. 
Some have bred this year (1911), but I have never seen them away from the 
mangroves.” 
Gould described this species as a member of the genus Eopsaltria , and 
some years later Salvadori recognised it as the species named by S. Muller 
pulverulentus. This name was never published by Muller, but appeared in 
Bonaparte’s Conspectus Genera Avium (Vol. I., p. 358, Feb. 1851), under the 
genus Myiolestes, as follows: “ilf. pulverulentus Mull., Mus. Lugd., ex 
N. Guinea. Grisea ; subtus alba .” 
The only recognisable species of that genus was Muscicapa megarhyncha 
Quoy and Gaimard, and I contend that the above description is so inadequate 
as to be absolutely unrecognisable, and therefore cannot be used as a valid 
name. I therefore retain Gould’s name, and if pulverulentus can be used 
at all, it must date from the later Salvadorian description. A series has 
recently been received from the Mullerian type locality, and these are refer- 
able to Gould’s species. Hartert described as a distinct species the mid-West 
Australian form, but in my “ Reference List ” I reduced it to subspecific rank, 
and named two other Australian subspecies as follows (I had lumped all 
these in Pachycephala ) : 
Pachycephala leucura alligator. 
“ Differs from P. 1. leucura in its larger size and darker head and lores. 
Alligator River, Northern Territory. 
Pachycephala leucura connectens. 
“ Differs from P. c. cinereiceps in having a darker head and back. Point 
Torment = Napier Broome Bay, North-west Australia.” 
I later added : 
Pachycephala leucura greda. 
“ Differs from P. 1. alligator in its larger size and lighter upper coloration. 
Melville Island, Northern Territory.” \\ 
and 
Quoyornis leucurus normani. 
“ Differs from Q. 1. leucurus in being distinctly paler above and lacking 
the band on the upper-breast. Norman River, North Queensland.” 
Recording additions to H. L. White’s Collection, Campbell wrote : “ Birds 
collected by H. G. Barnard and myself at Cardwell, North Queensland, appear 
similar to Northern Territory specimens, from which Mathews’s connectens 
from the farther north-west are doubtfully separable. Two males E. L. 
Whitlock collected at Cossack are probably not fully adult, the plumage being
