than in aS. />. danei, altliouoh there is no appreciable dif- 

 ference in measurement. The wing is, however, 3 mm. 

 shorter : I have compared it with a specimen of S. h. bohni 

 from Cameroon, No. 5639 in the British Museum collection. 

 The measurements of S. h. danei are as follows : — Total 

 length in the flesh (from tip of bill to tip of toe) 6^ inches. 

 Bill 13 mm., wing 84, tail 34, tarsus 24. 



Iris dark brown, eyelids chestnut ; bill, upper mandible 

 black, lower Indian purple ; feet brownish plumbeous. 



Type. S (in breeding condition), Reg. No. 1920.5.15.204, 

 in the British Museum. Caught at sea on board H.M.S.

Named in honour of Captain Dane, R.N., to whose 

 generosity and interest in Ornithology we are indebted 

 at the Natural History Museum for a fine collection of 

 West African birds made this year by Mr. W. P. Lowe, 

 while Capt. Dane's guest on the ' Dwarf.' 



Ohs. There is a specimen of what I believe to be this new 

 Rail in the British Museum obtained at Bo, in Sierra Leone, 

 by Robin Kemp in 1904, erroneously recorded at the time 

 as *S'. honapartel. 



Sylviella flaviventris nigeriae, subsp. nov. 



Evidently a local race of S. flaviventris flaviventris from 

 the Gold Coast, and is distinguished from it by having the 

 head greyer, less brown, and in having the back slightly 

 more olive. The distinguishing shades are difficult to 

 describe, but the difference is perfectly apparent when the 

 two races are examined side by side. The under-parts are 

 very similar, but in the new race the white of the belly 

 extends further up towards the breast. Three specimens 

 were obtained. 



Bill, upper inanflible dark horn-, lower flesh-colour ; iris 

 reddish-brown ; feet dark flesh-colour. 



Bill 11 mm., wing 49, tarsus 17.
