Mr. W. P. Lowe on the 
[Ibis, 
Centropus senegalensis senegalensis. Senegal Coucal. 
One of the commonest birds, occurring everywhere. 
Ceutlimochares aereus flavirostris. Yellow-billed Coucal. 
A fairly common bird. 
Tachornis parvus brachypterus. Short-winged Palm-Swift, 
One of the most common birds. 
Scotornis climacurus. Long-tailed Nightjar. 
This is quite a common bird. On 16 March I found a 
bird sitting on some reddish-coloured ground amongst the 
cassava. I went close up to it and it refused to move until 
I practically touched it with my hand, when it flew away 
a short distance, leaving two eggs, which were brought home. 
Their colour matched the ground wonderfully well. 
Lophoceros semifasciatus. Half-barred Hornbill. 
Tolerably common. 
Bycanistes fistulator. Piping Hornbill. 
Moderately common and noticed feeding on berries. 
*Bucorvus sp. ? Ground-Hornbill. 
A pair of Gfround-Hornbills inhabited the island. Unfor¬ 
tunately, I was not able to obtain a specimen, though I 
and others saw them many times. In size they resemble 
B. abyssinicus , but differ from that bird in being entirely 
black throughout, including the head and neck. They are 
known to the natives as “ Woodcock,” and are said to occur 
on the mainland, but I failed to find any. The beat of the 
wino- is audible at a considerable distance. 
O 
[It seems very probable that the Ground-Hornbill seen by 
Mr. Lowe on Tasso Island will prove to be an entirely new, 
undescribed species. A race (if recognised as such) of 
B. abyssinicus is certainly known to inhabit parts of West 
Africa, and is recorded by Reichenow from Portuguese 
Guinea. This form was named by Schlegel “ Buceros 
carunculatus , var. guineensis on account of its supposed 
smaller size etc., but Reichenow (‘ Vogel Afrikas,’ ii. p. 234)
