ABYSSINIA AND THE BOGOS COUNTRY. 279 
The female of this species is a fourth less than the male, with a smaller beak; the 
skin under the chin is black instead of coloured. The anatomical structure of this bird 
is singular; each muscle stands well separated from the others; and between the skin 
and the body is an open space, the first not adhering to the latter, as in most birds, but 
attached by a number of threads or ligaments. It appears possible that this vacant 
space can be filled with air, especially as the flight of this bird is singularly light. 
These peculiarities apply also to Bucorax abyssinicus, and, I believe, to others of the 
family. Contents of stomach seeds and stones of fruit and small coleoptera. Did not 
meet with this bird higher up than Rayrayguddy.—W. J.]

I only obtained two specimens of this species near Senafé, towards Rayrayguddy, and, 
being at the time much engaged with preparations for returning to Zoulla, had no time 
to make further notes. I never obtained or saw this bird afterwards in Bogos or else- 
where.—. J.|

[Iris brown ; eyelid horny, lashes bristles; beak black, surmounted at base by a hollow 
casque, which appears as though broken off, leaving the hollow part exposed ; a little way 
down the hollow portion of the casque there is a membrane across, somewhat similar to 
the inside of a reed-joint; skin round the eye blue and black ; under throat blue with 
some red, in the female the same, save the red. 
I found this bird at Senafé and Facado in May; Bejook on the Anseba, July, and also 
saw one as low down, and near the coast, as Ain in August; I never saw them regularly 
in the plain. It is useless to give a description of the habits of this bird, as Antinori 
has already done so with great accuracy, omitting, however, the bird’s note, which is
