Obs. We have now two adult females and five immature 

 specimens in the British Museum. 



Immature. The young birds resemble the adult females, 

 but their throats are greyish, the underparts pale not bright

 tinge of scarlet. 



Mr. Ogilvie-Grant long ago recognised that the immature 

 specimens belonged to an undescribed race, but hesitated to 

 describe the only adult skin in case the bird proved to be an 

 aberration. As we have now received further examples 

 from Mr. Bates which exactly resemble the one alluded to, 

 I see no good in refraining any longer from describing the 

 bird, which I now name after my old friend Mr. W. R. 

 Ogilvie-Grant. 



Dr. C. B. TiCEHURST showed a series of the young of the 

 Common Indian Sand-Grouse (Pterocles senegalensis) [=P. 

 exustus auct.] to illustrate the stages of plumage from the 

 chick to adult. He pointed out that the sequence of plumages 

 in (Sand-Grouse had been hitherto unrecognised, and he 

 believed that the specimens shown were the only ones of 

 any species which threw light on the subject. The specimens 

 were obtained by himself in Sind, and the stages were clearly
