In _Novitates Zoologicae_, XXV. 1918, I have, with the help of Arthur Goodson, reviewed the African Green Pigeons of the _calva_ group. We were able to distinguish not less than nine sub-species, and there seem to be one or two other, still doubtful ones, in N.E. Africa. In the _Catalogue of Birds_ in the British Museum all these nine forms were united, while Reichenow separated two, and recently four different ones. The specimens from East Africa have given us the greatest trouble. It is evident that a distinct form with a very short naked ‘cere’ or basal portion of the beak, and with a sharply defined lavender-grey nuchal collar, is found in East Africa around Kilimanjaro and thence to the Athi River, Machakos, Matabato Hills, and to the Kikuyu Mountains and Escarpment. This form we called _Treron calva brevicera_. (init.) “E. H.” “No. 152. _Motacilla clara_ (Long-tailed Pied Wagtail). This is the bird which used to be called for many years _Motacilla longicauda_, but as this name had been preoccupied, Sharpe named it _Motacilla clara_ in the fifth volume of the _Hand-list of Birds_.

Rendle of the British Museum, and was fortunate to secure some interesting species, four of which were new, and not formerly recorded, and have been described in the _Journal of Botany_ (October, 1916), while others, unfortunately, were too fragmentary to determine, or to give more than a genus name, though nine of them are possibly new species. The East African plants obtained were: CAPPARIDEAE _Cleome hirta_ Oliv. PORTULACACEAE _Talinum cuneifolium_ Willd. TILIACEAE _Grewia canescens_ A. Rich. GERANIACEAE _Pelargonium_ sp. LEGUMINOSAE _Vigna fragrans_ Bak. fil. _Rhynchosia_ sp. RUBIACEAE _Pentas carnea_ Benth. (forma) _Oldenlandia Bojeri_ Hiern COMPOSITAE _Erlangea Buchananii_ S.
