Mr. W. P. Lowe on the 
[Ibis, 
appears to be an nndescribed species. It is an enormous 
bird, a pair of which were seen by Mr. Lowe on more than 
one occasion, and is remarkable for the fact that it is entirely 
black, lacking the white primaries of B. abyssinicus and 
B. cafer. As no example of Bucormis with black primaries 
is known to exist anywhere in Africa, a specimen should be 
secured at the earliest opportunity. 
I wish to take this opportunity of expressing the great 
appreciation felt by the authorities of the Natural History 
Museum to Commander Dane, R.N., for so generously taking 
Mr. Willoughby Lowe with him as naturalist on his ship. 
Much of the material obtained by Mr. Lowe (including a 
large collection of birds from Lagos, Southern Nigeria) still 
remains to be worked out, but it will be apparent from a 
perusal of this paper how much valuable work Mr. Lowe has 
accomplished, thanks very largely to the facilities afforded by 
Commander Dane, who spared no pains or personal expense 
to make the trip a success. The new Rail and a fine 
Antelope have been named after him as a small recognition 
of his kindness. 
Introduction .—By Willoughby P. Lowe, M.B.O.U. 
Having been kindly invited by Lieut.-Commander A. Y. 
Dane, R.N., of H.M.S. 4 Dwarf, 5 to accompany him in his 
gunboat to the West Coast of Africa, I found myself once 
again off Freetown, Sierra Leone, on 25 February, 1920. 
My first object was to try and complete the collection made 
on my last visit of 1911 whilst the guest of Capt. Hardy, 
11 .N., of H.M.S. 4 Mutine.’ It was now arranged that I should 
stay on the high ground at Hill Station, and from this point 
many new additions to my former collection were made, as 
well as new records to the list of known Sierra Leone birds. 
Having about exhausted the birds found in the immediate 
neighbourhood of Freetown, it was with much interest and 
pleasure that Commander Dane and myself left the ship early 
on March 12 for the zoologically unexplored Rokelle River 
and its numerous islands. We arrived at Tasso Island (text- 
fig. 3) about 11 A.M. An empty bungalow was to be had, and
