BEACHYPTEEYX POLIOGENIS. 
“ This curious bird was obtained by Mr. Wilson from M. Verreaux, 
with the words ‘ Myiothera poliogenys, Boie, Borneo,’ attached. 
It evidently belongs to the genus Brachypteryx of Horsfield, but 
differs from his type-species in the shortness of its tail, which gives 
it a great analogy (though in my opinion no affinity) to some of the 
American Formicariince, such as Formicarius, Leptorhynchus , &c. 
Like the other Timaliine birds which abound in the Malasian Ar- 
chipelago ( Malacopteron , Macronus , &c.) the rump feathers are 
remarkably long and dense, and when expanded laterally, seem 
admirably adapted to protect the bird from tropical showers. 
“ I have altered the spelling of the specific name from poliogenys 
to poliogenis , as the former word would imply grey-bearded in- 
stead of grey-cheeked. 
“ Crown dirty brown, with a rufous tinge ; back and wings pure 
brown, passing into tawny towards the rump ; rectrices fuscous 
brown, margined with rufous ; circuit of the eye and cheeks pure 
grey, passing into black towards the angle of the mouth; lores 
whitish ; chin white ; breast, sides, lower wing-covers, thighs, and 
lower tail-covers, pale tawny ; middle of belly white ; upper man- 
dible corneous ; lower whitish ; feet and claws pale yellowish. 
“ Total length, 4.5; beak to front, 6; to gape, wing, i. 5; 
medial rectrices, i .2; external, i.i; tarsus, i.'i; hind toe and 
claw, 6; middle ditto, 8.” — H. E. Strickland.
