BIRDS OF ETHIOPIA AND KENYA COLONY 



161 



The Siberian birds have been separated, on the basis of larger sizfe, 

 wing 196-213, bill 29-34.5 as against wing 189-201, bill 28-30.5 

 millimeters in typical material. This northeastern form, hypo- 

 melaena, is said by Meinertzhagen ®^ to occur in winter in northern 

 Somaliland, while the birds of the Kenya coast are squatarola. The 

 single specimen collected by Mearns has a wing length of 189 milli- 

 meters, the minimium for squatarola as given by Hartert ''° and a bill 

 33 millimeters long, nearly the maximum for hypotnela^na. It is 

 obvious that the two forms can not be maintained. The North 

 American cynosurae is likewise unrecognizable, A series of 77 birds 

 gives the following results (from data tabulated by J. L. Peters, 

 based on the material in the Museum of Comparative Zoology). 



An adult male from Dar-es-Salaam, Tanganyika Territory, is 

 much smaller than any other specimen, having a wing length of only 

 179 millimeters. 



Sclater ^^ records only the typical form (he uses trinomials) from 

 Africa. However, if the races are to be recognized it seems that 

 hypomelaena should be added to his list.
