Rare in the Steppes of the Kitsch-Negroes, on the western 
shore of the Bahr el Abiad. Itmiay be the same as T. rnarga- 
ritatus, but I have never met with this species in Kordofan. 
I now add descriptions of the newly-discovered species, which 
are represented in the accompanying Plate. 
1. POGONORHYNCHUS ROLLETI. (Plate Y. fig. 1.) 
Coracino-niger, tergi macula, et hypochondriis pure a]bis, his 
ex parte nigro-striolatis: remigibus fuliginoso-nigricantibus, 
subtus, interne et basin versus pallidioribus, externe cora- 
cino-limbatis : subalaribus cinereis, flexuram versus cora- 
cinis: abdomine medio et crisso intense cinnabarinis: 
orbitis nudis, violaceis : rostro valido, pallide virescente, basi 
cserulescente, maxilla bidentata, simpliciter sulcata, man- 
dibula non plicata: vibrissis rigidiusculis nigris: iride 
brunnea: pedibus plumbeo-fuscis : long, tota 10 3, rostri a 
fronte 1*4, ab angulo oris 1*5, alse 4*15, caudse 3*15 poll, 
et lin. Gall. 
This species is distinguishable from P. dubius (of Senegambia) 
by important characters, such as the absence of red on the head, 
and a different formation of the bill. The whole bird is nearly 
entirely of a shining blue-black, with the exception of a large 
white spot on the back, and the sides of the belly, which show 
a few fine black markings, and some flame-coloured streaks to¬ 
wards the breast. The middle and lower part of the belly is of 
a lively cinnabar-red on a white ground; the wings are smoky 
grey on the inner web, the feathers getting gradually lighter 
towards the base. The under wing-coverts are likewise smoky 
grey, becoming towards the wing-margins bluish black. The 
upper beak has on each side a single deep furrow, within which 
the bristles are placed: the latter are about half the length of 
the beak; the colour of the beak is light greenish yellow, bluish 
towards the base. The feet and nails are greyish brown. 
The sexes are coloured alike, but the female is a trifle smaller 
in dimensions. This species is rather numerous on the Upper 
White Nile, particularly on the Sycamore trees, the fruit of 
which supplies a favourite food for all the species of Capitonidce.
