Genus— MUSCITREA. 
Muscitrea Blyth, Journ. As. Soc. Bengal,

Type (by monotypy) ... ... ... Tephrodornis grisola Blyth.

designation) ... ... P achy cephala orpheus Jardine. 
The genus Muscitrea was introduced by Blyth for an Indian bird with which 
the North Australian P achy cephala simplex Gould has been considered con- 
specific. It is fortunate that Gould’s name is older than Blyth’ s, so that we 
can use the correct name whether Blyth’s species is different or the same. 
This species has somewhat the facies of the Eopsaltria series and, according 
to McLennan, in its manners recalls the preceding. 
The bill is long and heavy, more like that of Eopsaltria than true 
P achy cephala ; the first primary is long and narrow more than half the length 
of the third, which is a little longer than the second ; the fourth, fifth and 
sixth primaries are equal and longest and the seventh exceeds the third, the 
eighth being longer than the second ; the tail is of medium length and the 
legs are short and delicate. 
It is probable, as suggested in connection with the preceding genus, that 
skeletal skull characters may assist in locating correctly this species, but it 
must be remembered that in the Passerine groups there are no “ deep-seated ” 
internal features available for generic groupings. I find that anatomists have 
been using single specimens for comparison and noting characters which, had 
the bird skins been used, would have been reduced to subspecific value.
