LARGE PIN-TAILED SAND-GROUSE. 13 



ten ; when flashed, rises with a low chuckling call, takes a short 

 flight at no great elevation, and drops into cover again. I have 

 very rarely seen it among rocks, where there was little or no 

 jungle. I have had the eggs brought me, very cylindrical in 

 form, of a dull earthy green with a few dusky spots. On several 

 occasions I have observed in this species crepuscular, if not noc- 

 turnal habits. On one of these several flew round a field on 

 which I was encamped, near the Nerbudda, late one evening 

 when nearly dark, alighting every now and then, and again re- 

 suming their flight, which, being particularly noiseless, led me 

 to take it for some kind of Caprimulgus at first ; and more than 

 once I again noticed similar habits. 



P. ldchtenstebii is not unlike P. fasciatus, but differs in being 

 larger, with the nape, front and sides of neck, and the fore part 

 of the wing, prettily variegated. It is common in Arabia, and 

 may occur as a straggler in Sindh, or in the Western Punjab. 



With the medial tail-feathers greatly lengthened (Pteroclurus,
