in Beloochistan and Persia, it becomes more common, breeding freely 

 at Bushire. 



Mr. J. W. N. dimming, to whose kindness I am indebted fof a 

 clutch of eggs of this species, has most obligingly furnished me with 

 the following note, which is at present the extent of our information 

 regarding the breeding of this somewhat rare bird : — 



" Once only have I come across the nest of the Gre} r -backed War- 

 bler, and that on the 14th April 1884, in the telegraph garden at 

 Bushire. It was placed inside (a few inches from the top) of one of 

 a number of old hollow telegraph posts, standing about three feet 

 out of the ground, and forming supports to the wire fencing sur- 

 rounding the garden. The eggs, four in number, were entirely cover- 

 ed with minute yellowish-brown spots and very pale purple blotches, 

 hiding almost completely the white shell, and are similar in shape to r 

 though a good deal larger than, those of Thamnobia cambaiemis. 



" The nest was cup- shaped, and the materials consisted of fine grass-, 

 well lined with hair and fibres. In the evening of the same day, the 

 female was caught seated in the nest, about to lay its fifth and last 

 egg, for, on dissecting the ovary, after the removal of the skin, I 

 found an entire and perfect egg, which would in all probability have 

 been laid that night. 



"My brother, also, when at Fao, came across a number of nests of 

 this species, chiefly in holes in walls and on date trees, in the hollows 

 at the bases of the leaves." 



The eggs are very similar in shape and colour to the thickly speckled 



type of egg so commonly met with amongst those of Thamnohia 



cambaiensis et fuUcata, but are rather larger, those in my collection 



measuring 0*82 inches in length by rather more than 0*62 in breadth. 



Strictly speaking, an account of the nesting of this bird ought not 

 to appear in this paper, as it has never been found breeding in this 

 Presidency, but I have been assured that since the present arrange- 

 ments for the supply of water at Karachi, this and several other rare 

 birds have become more common, and it is not unlikely that sooner 

 or later a nest will be found.

The Brown Rock-Chat is very common at Mount Aboo, and in the 

 vicinity of JNeemuch, Rujpootanu.
