thinks it is probaljly the female of liis two male birds from 

 Nairobi and Kisnmn, which he believes are distinct from 

 S. bohmi. If this is the case, it must, of course, be known 

 as Sarothnira 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 Saruthrura 

 bohitii 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 biJhmi, we shall have : —

A. single example of this Rail appears in the collection 

 which Mr. Bates has now sent to us. It is a male bird iu 

 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 concUisions as Dr. van Someren Iiad 

 done working at Triiig, aiul as he has now descrii)ed two of 

 these forms in the Bull. B. O. C. vol. xl. 1919, p. 20, I will
