The first paper on the list is a supplement to a previous 

 one by tiie same author on the birds of the southern portion 

 of what was previously German East Africa, published in 

 the same journal in 1913-14, It contains comments on 

 several species, and a description of two new subspecies — 

 Estrilda astrild litoris and Lagonosticta rubricata reichenowi. 



The second paper on the list is a review of the subspecies 

 of the iittle grey Flycatcher, Alseonax niurinus, which is 

 found throughout the greater part of tropical Africa in 

 mountainous districts under slightly varyiug forms. The 

 review is based on the examples in the Berlin INIuseum, 

 though the author allows that it cannot be really satis- 

 factory without a direct comparison with the specimens in 

 the British ]\iuseum. One new form, A. m. subtilis, from 

 Beni, west of the Semliki river, is here described. 



Herr Grote's last paper deals with a considerable collec- 

 tion of birds made by a German missionary, Pater Conrads, 

 in 1908-9, on the large island of Ukerewe in the southern 

 half of Lake Victoria. The collection, consisting of 750 

 skins representing 174 species, is in the Berlin Museum 

 and is now listed for the first time. The geographical 

 relations of the avifauna are partly with Reiclienow's 

 " Great Lakes subregion," partly with the avifauna charac- 

 teristic of the inland districts of eastern Africa. Another 

 interesting feature of the avifauna of Ukerewe is the large 

 number of Paleearctic wintering-birds, such as Acrocephalus 

 arundinaceus, Budytes flavus thunuergi, Hirundo rustica, 

 Coracias garrulus, Tringa glareola, and T. hypoleucos. 



Three new forms had been previously described — Rhino-
