thinks it is probably the female of liis two male birds from 
Nairobi and Kisumu, which he believes are distinct from 
S. bohmi. If this is the case, it must, of course, be known 
as Sarothrura bohmi somereni. 
While this paper was in the press I received yet another 
form of this Rail, caught at sea in lat. 10° 0 ; N., 
long*. 15° 30' W. off the coast of French Guinea by 
Mr. W. P. Lowe. I have named this bird Sarothrura 
bohmi danei in the Bull. B. O. C. xli. p. 5, October 1920. 
It is very much blacker on the underparts than the typical 
form and is darker on the back, but other differences exist 
and are set forth in the original description. 
If Dr. van Someren is correct in thinking S. somereni 
a race of bohmi , we shall have :— 
1. Sarothrura bohmi bohmi Rcliw. 
Type loc. : Likulwe, Belgian Congo. 
Range. Belgian Congo, probably westwards to Came¬ 
roon. 
2. Sarothrura bohmi somereni Bannerman. 
Type loc.: Macliakos. 
Range . Kenya Colony. 
3 . Sarothrura bohmi danei Bannerman. 
Type loc. : At sea off French Guinea. 
Range. Unknown.

A single example of this Rail appears in the collection 
which Mr. Bates has now sent to us. It is a male bird in 
adult plumage. Whilst working at this group of Rails, I 
had the advantage of examining a series of birds which 
Dr. van Someren sent to me for my opinion as to their 
being one or two new subspecies represented. I arrived at 
very much the same conclusions as Dr. van Someren had 
done working at Tring, and as he has now described two of 
these forms in the Bulk B. O. C. vol. xl. 1919, p. 20, I will
