TRICHOSTOMA UMBRATILE. 
(Hind Figure ). 
Among the birds lately purchased by Mr. Wilson from M. Verreaux, 
and obligingly communicated to us by the former gentleman, are two 
distinct species, which resemble each other considerably in colour, 
and which M. Verreaux seems to have confounded together, as both 
birds bore the same MS. title “ Napothera umbratilis, Temm.” The 
localities however are different, one being from Borneo and the 
other from Celebes. The above specific name being, I believe, un- 
published, I have no means of deciding which of the two species 
M. Temminck intended to designate umbratilis ; but not wishing 
to supersede this title altogether, I have retained it for that species, 
which, from its pure umber colour, seems best to deserve the name. 
These two birds belong to that peculiar Malasian group of shrike- 
like or thrush-like birds, distinguished by the density of their dorsal 
plumage, of which the genus Tinialia is the type. In the general 
form of their beaks they approach Malacopteron , Eyton, and 
Goldana, Blyth ; but the considerable development of the rictal 
bristles refers them to a separate genus, which Mr. Blyth terms 
Trichostoma. 
The species to which I retain the specific name umbratile, in- 
habits Borneo ; and in the length of the rictal bristles and breadth 
of the beak, makes the nearest approach to Mr. Blyth’s typical 
Trichostoma !. The whole upper plumage is rich rufous brown, 
darkest on the head, and becoming more rufous on the outer mar- 
gins of the secondaries and rectrices ; chin and middle belly whitish , 
breast and sides dirty brown ; beak dark corneous ; legs pale ; first, 
second, and third primaries, graduated ; fourth, fifth, and sixth, 
equal and longest. ..
