darker than that of Palestine, and is separable as a sub- 

 species on those grounds, as pointed out by Neumann. 

 The type-locality of Argija s. squamiceps Cretzsch. is Akaba^ 

 far to the north on the borders of Palestine. There is a 

 large series of the southern A. s. yemensis in the British 

 Museum from the neighbourhood of Aden as well as from 

 Muscat. It appears to be a common species.

I have very carefully compared these and other examples 

 from southern Arabia in the British Museum with examples 

 from Palestine, and I am quite unable to detect any diflfer- 

 ence between the two series. Lorenz & Hellmayr state that 

 the southern Arabian birds are much smaller than those from 

 Palestine, but I find that the wings of the males average 

 97 mm. and the females 91 mm. in both northern and southern 

 birds, nor can I confirm any of the other distinctions pointed 

 out by Lorenz & Hellmayr for their P. relche?ioivi.
