624 Col. It. Meinertzhagen on Birds from [Ibis, 
El Tor. The bird is not black as krausei should be, but has 
the coppery plumage of ruficollis. 
As regards other Sinai birds, through the kindness of 
Professor Koenig, who has a series from Sinai, I am able to 
give the following measurements :— 
Wing 350-378 ; culmen, length 57*5-62*5, height 21-22*5. 
Zedlitz (J. f. 0. 1912) gives the following measurements 
for his series of krausei from Sinai :— 
Wing 355-375 ; culmen, length 58-64, height 21-23. 
Two birds from Nekhl (central Sinai) in the Giza 
Zoological Museum measure: wing 387-405; culmen, length 
59-63, height 23 ; whilst a female in Koenig’s collection 
from Sinai has a wing of 385 mm. (J. f. 0. 1918, p. 147). 
So Sinai birds have a wing varying from 350-405, and a 
culmen whose length is from 57*5 to 65 mm. and height 
from 21 to 25 mm. 
Now from the series in the British Museum, Tring 
Museum, Giza Zoological Museum, and in my own collection, 
I have obtained the following measurements :—

On these measurements I am unable to substantiate 
krausei or infumatus , and therefore shall treat them as 
synonyms of ruficollis.
