partly due. But we quite agree with Dr. Reichenow that 

 by far the greater proportiou of this vast work has been 

 accomplished by the indefatigable energy of his fellow- 

 countrymen. Hildebrandt, Fischer, Bohm, and Emin Pasha 

 alike sacrificed their lives to the scientific exploration of 

 Eastern Africa, and two others — Stuhlmann and Neumann — 

 who have also done much^ are still, happily, living and con- 

 tinuing their collections in the same country. To this 

 historical account is appended a list of 81 publications which 

 refer to the ornithology of German East- Africa. 



In the second chapter Dr. Reichenow proceeds to explain 

 the relation of the avifauna of the German East-African 

 Protectorate to that of the whole continent. He points out 

 that the Protectorate belongs mainly to the S.E. steppe- district 

 of Africa, though at the western border it intrudes on the 

 great W est- African wood-region. Of the 728 species of 

 birds yet recognized within its limits, about 30 only are 

 western forms, and the remaining 690 are south-eastern. 

 After several pages of instructions as to collecting and pre- 

 serving birds, the rest of the work is devoted to the sys- 

 tematic account of these 728 species, commencing with the 

 Struthionidse and ending with the Sylviidse, according to the 

 fashion of Dr. Reichenow's system. Short characters are 

 given not only of the species, but also of the higher groups,, 

 and a number of "keys^^ are likewise introduced. We 

 regret the entire absence of synonymy. No doubt it would 

 have increased the bulk of the volume considerably, but we 

 think it would have been better to have quoted the references 

 that specially relate to occurrences within the Protectorate. 

 "VVe may also remark that, though exact localities are assigned 

 to each species, no authorities are added for these occur- 

 rences. The numerous illustrations, plain and coloured, 

 introduced into the text will be of material assistance to 

 those who use this volume as a handbook.
