 Meadow-Pipit, AntJms pratensis, from Kent, showing true 

 erythrism. He said that this was the first authenticated

Col. R. Mhinertzhagbn exhibited a new form of the 

 House-Sparrow from the Sudan : — 



Passer domesticus lialfse. 



Very similar to Passer d. arhoreus, but larger and not so 

 bright. Upper tail-coverts and rump are pure smoke-grey, 

 whereas in P. d. arhoreus these parts nearly always have 

 some chestnut edgings. Back with not such an intense 

 chestnut. Is at once distinguished from P. d. niloticus, from 

 the Egyptian Delta, by the larger extent of a brighter, 

 purer chestnut. Differs from P. d. indicus in having the 

 top of the head a paler, brighter blue-grey, and in being 

 slightly smaller. Wing of 5 males, 73-80 mm. 



Type in the Tring Museum, (^ , Wadi Haifa.
