Birds of Gazaland, Southern Rhodesia. 35 
appears to me to indicate that it is due in part to mere 
social instinct. 
I may frequently, in the following notes, have occasion to 
mention the “ Gumiti-berry,” a small bright yellow fruit 
with yellowish milky juice and a hard black pyramidal seed, 
the product of a large Urticaceous forest-tree, not yet 
identified. It appears to be greatly relished by the forest- 
birds, even those that are most insectivorous, and supplies 
them with food for several months in the year. 
I take this opportunity of heartily thanking Capt. G. 
EK. Shelley for his kindness in determining a number of 
specimens sent to him and in revising the present notes. 
I wish also to thank my old friend, Mr. Guy F, Marshall, 
for his never-failing help and encouragement. 
The following list is obviously anything but complete. 
I was able to devote very little time to the subject until 
a year ago, and in particular have had no opportunity of 
examining any of the larger rivers, all of which are said to 
be extremely rich in water-birds. Moreover this district 
is anything but deficient in Weavers, Warblers, and many 
other families which are but poorly represented in my list. 
[Along with the present paper Mr. Swynnerton forwarded 
to England a collection of skins, which Capt. Shelley care- 
fully examined during his study of the MS. He described 
two new species from it at the meeting of the B.O.C. in 
June 1906 (Lrithacus swynnertoni and Apalis chirindensis), 
but (owing to ill-health, I regret to say) has not been able to 
complete his revision. Besides these novelties it appears 
that the following twelve species from Mr. Swynnerton’s 
collection are new to the Fauna of South Africa south of 
the Zambesi, not being included in Mr. W. L. Sclater’s work 
on that subject :— 
Estrilda clarkii (p. 39). Sylviella whytii (p. 56). 
Nectarinia arturi (p. 42). Monticola sp. ine. (p. 60). 
Cinnyris niassve (p. 45). Erithacus swynnertoni (p. 61). 
Telephonus anchietze (p. 47). Pachyprora dimorpha (p. 69). 
Laniarius bertrandi (p. 48). Trochocercus albo-notatus (p. 70). 
Phyllostrophus milanjensis (p. 54). Terpsiphone plumbeiceps (p. 71).
