aro entirely insectivorous, feeding on larva3, " white ants," 

 etc. The note is not unlike the alarm chuckling of a Black- 

 bird but jnuch softer, and it has another alarm-note like the 

 Redwing's call. Males far outnumber females, and even so 

 some of the apparent females are males of the first year. 

 The earliest I have seen it at Karachi is 25 November and 

 the latest 23 March. 



Capt. Maiden informed Hume that he had obtained 

 Tardus unicolor at Jacobabad ; Hume apparently did not 

 see tlie specimen, and Maiden's identification cannot be 

 relied on. 



Monticola solitarius longirostris (Blyth). 



Monticola solitarius pandoo (Sykes). 



The Blue Rock-Thrush is not uncommon in the Khirthar 

 Range and, at places where the few perennial streams such 

 as the Gaj and Nurree Nai flow through them, it is abundant, 

 even down as low as GOO- -700 feet. The only one I person- 

 ally met with was at the bottom of a ravine on tlie Cape 

 Mon/e range west of Karachi on 3 February ; this range is 

 about 800 feet high, but the bird was practically at sea-level. 

 In Lower Sind it appears to be very local, and to the plains 

 it is evidently quite a rare straggler ; it is only a winter 

 visitor to Sind. 



As indicated above two races occur : from the Khirthar 

 Hills, Seliwan, and Karachi are males in the British Museum 

 obtained by Hume and Blanford, and these all belong to the 

 paler and larger race loiujirostvis. The female I obtained, 

 however, certainly does not belong to this race but to pandoo ; 

 females of this Rock-Thrush are more easily differentiated 

 than males, and this bird is far too dark for lomjirostris and 

 matches well topotypes of pandoo. From a series of topo- 

 typcs of each race : — 



solitarius. cJ: wing 122-127 mm. 



lo)if/trostris. rS : ,, 121-127 mm. Males paler; females greyish 



brown above, less darii and less rufescent below 



than in the other two races.
