WHITE'S Ground Thrush (Geocichla varia, Pallas) is a very 

 rare abnormal autumn migrant to the British Islands from 

 Southern Central Asia. The adult (which cannot well be 

 confounded with any other of our British thrushes) has the 

 upper parts of plumage olive-brown, with black tips to the 

 feathers ; under parts white, tinged with buff, and marked 

 with black crescent-shaped spots ; the tail consists of four- 

 teen feathers. Length, about twelve inches.
