1921 .] Recently published Ornithological Works. 5G3 
two previous volumes, and a good many subspecies not 
mentioned in Hartert's Yog. pal. Fauna are discussed at 
length. Count Zedlitz commences a similar series of 
articles on the birds of the eastern front, dealing with the 
collections and summarizing the observations of various 
other ornithologists, as well as his own, on the birds in the 
vast swamps of the head-waters of the Pripjet River in 
southern Poland and the neighbouring parts of Russia—a 
melancholy region, wild and inaccessible, and but sparsely 
inhabited by man though swarming with birds. Another 
paper, also in several parts, dealing with the birds of 
the Ural region in eastern Russia is from the pen of 
Mr. H. Grote. 
Mr. Oscar Neumann contributes a long list of new genera 
and of subspecies from different parts of Africa. These, he 
states, have long been known to him, and indeed many of 
the types are in the Tring and London museums, which 
he visited before the war. But, as he moufnfully writes, 
seeing little chance® of securing further material for com¬ 
parison, he now publishes his old notes. The new genera 
are Knestrometophon for Sigmodus scopifrons Peters, Suaheli- 
ornis for Phyllastrephus kretzschmeri Rchw., Sathrocercus 
for Bradypterus barakce Sharpe, Vibrissasylvia for Callene 
cy omit hop sis Sharpe, and the new races described are 
sixteen in number. 
Another paper by Count Zedlitz reviews the eastern races 
of Certhia familiaris and C. brachydactyla, and includes 
descriptions of several new races ; while Dr. Reichenow has 
some remarks on the South American genus Cinclodes , and 
also adds to the number of described races. The last 
supplementary part is entirely occupied with portion of a 
work on the birds of Egypt by Prof. Koenig, of Bonn. 
It contains the accounts of the Insessores ( i . e. Picarians 
and their allies) and the Coraces (Orioles, Bulbuls, Star¬ 
lings, and Crows). Full diagnoses of the genera and species 
are given; also the names in English, French, and Arabic, 
and detailed accounts of the nesting-habit's and eggs of such 
species as breed there.
