and 110 such bird has ever occnrred on the Philippine Islands ! It is iilwaj-s a bad 

 cnstom to name a species from a figure, though it was regnlarl}' done in former 

 times, and, unfortunately, even now. 



43. Circus macrourus (Gm.) 

 <??,Zaria, 21. xi. 1912. 



44. Melierax canorus neumanni Hart. 



Melierax canoriis mil mniDii Huriert, Vog. pal. Faumi u. ^i. 1165 (Xubia to Xorthern Hausaland— 

 type (J ad., near Merowe, Nubia.) 



4 c?? ad., 2 juv., Zaria, September and October 1012. 



The adnlt birds vary considerably. Tliree have the secondaries and greater 

 npper wing-coverts white, heavily mottled with ash-grey mottlings, while in a third 

 they are much greyer, being grey with white mottlings. 



4.5. Polyboroides typicus typicus .Smith 



f? ? ad., Zaria (November). 



Both specimens — the S smaller, otherwise like the ? — have the underside, 

 from tbe chest downwards, barred. It is still, I think, a mystery what the meaning 

 is of the fact that sometimes adnlt birds have the underside, with the e.xception of 

 the vent, uniform grey, without white bars. We have in the Tring Museum two 

 such examples, both marked males, but other males are barred. 



46. Kaupifalco monogrammicus monogrammicus (Temm.) 



5 ad., Kaduna River, province of Zaria. 



This specimen belongs distinctly to the lighter form, while the darker 

 K. m. meridionalis is a more southern subspecies. The latter ranges in the west to 

 Angola, while the distribution in the east is not exactly known. I am inclined to 

 think that .specimens from Usegua and Tauga (Neumann coll.) agree better with 

 meridionalis than with typical monograminicus. 



47. Accipiter badius sphenurus (Riipp.) 



S ? ad., Zaria, September 1912. 



Juv., Kadsena, Zaria. 



Tiie amount of barring on the underside varies considerably, and I am inclined 

 to think that A. riggenbachi Neumann {Bull. B. 0. C. xxi. p. 69) is based on 

 exceptionally dark specimens of ^l. l>. sjilienarKs, typical specimens of which are 

 common in the Senegal colony, in the same place where the supposed " riggenbachi " 

 was collected, 



48. Circaetus gallicus (Gm.) 



2 ad., Zaria, November 1912. 



This is about the southernmost place from where this species is known. It is, 

 of course, only a winter visitor in tropical Africa.
