286 Mr. D. Bannerman : A Systematic List [Ibis, 
Mr. Willoughby Lowe’s second collection was made in the 
spring of last year (1920), mainly on the islands of the 
Rokelle River, when the guest of Commander Dane, R.N., 
as naturalist on board H.M.S. f Dwarf.’ 
This collection, which I had the opportunity of working 
out, comprised 207 skins, representing 118 species and 
subspecies, including 32 birds new to the colony, and forms 
the basis of Mr. Lowe’s paper published in the current 
number of ‘ The Ibis ’ ( cf . pp. 265-282). 
Commander Dane has generously presented the birds 
obtained to the Natural History Museum, where they form 
a most valuable addition to our West African collections. 
In the following pages I have attempted to bring up to 
date the list of birds known to have occurred in the Sierra 
Leone Protectorate, somewhat on the lines of Professor 
Neumann’s List of Birds of the Lower Senegal Region 
[cf. Journ. Ornith. lxv. vol. ii. 1917, pp. 189-213.) 
The specific or subspecific name of the race to which the 
form is now supposed to belong is given in full, together 
with the author of the name used. Following this are the 
names of the collectors who have actually obtained the birds 
against which the names are placed. 
With the exception of Afzelius, Kemp, Kelsall, and 
W. P. Lowe, the other collectors mentioned have only 
obtained a few odd birds, which have either been noticed 
casually (as, for instance, those of Dr. Fergusson) in such 
wrnrks as ‘ The Catalogue of the Birds in the Collection of 
Sir William Jardine,’ or by Cassin or Fraser, who, in the 
various publications to which they contributed (vide List 
of Literature), usually mentioned the source from which 
their Sierra Leone birds had been obtained, and thus gave 
a clue to the actual collector of the birds described 
by them. Other collectors’ names, again, have simply been 
copied from labels* of Sierra Leone birds in the British 
Museum Collection. 
Lowe i. following a bird’s name in the List signifies that
