DUSKY THRUSH. 45 



rump, and upper tail coverts have the feathers more or less mixed 

 with rufous. Tail dark brown, having the basal outer webs of the 

 first three on each side rufous. Primaries brown^ the outer webs edged 

 with white, and the basal half rufous. Secondaries dark brown, deeply- 

 edged with rufous, giving a conspicuous redness to the wings. Lesser 

 wing coverts edged with cream-colour, forming a band near the 

 shoulder. Cheeks black; a broad cream-coloured streak above the 

 eye. Throat and neck cream-colour; a broad band across the crop 

 black_, mingled with cream-coloured feathers. Abdomen and under 

 tail coverts dingy white, the flanks mottled with rich brown more or 

 less. Tail feathers below smoky brown. Shoulders and axillary 

 feathers rufous, mottled on the former with white. Rest of under 

 wing rufous, with brown ends. Lower mandible yellow at base. 

 Length nine inches and one fifth; carpus to tip five inches and one 

 fifth; tarsus one inch; tail three inches and a half; beak one inch 

 and one tenth. 



An adult female, marked "Shangai, March, 1873," differs mainly 

 from the above in having less and paler rufous on the upper parts, 

 and a more imj^erfect band across the upper chest. It is also smaller. 



A young bird, marked "Ningpo, November, 1868," difiers in having 

 still less and paler rufous on the wings; no black pectoral band; but 

 having the chest, neck, and throat covered with dark brown spots. 

 It measures only eight inches, wing four inches and a half, while 

 the beak is entirely black, like that of the young Naumanni. 



The birds figured are the adult male above described, and a fine 

 immature skin lent to me by Mr. GoLild, from Formosa, 



Mr. Dresser exhibited at the Zoological Society's Meeting, a year 

 or two ago, some eggs collected by Dr. Drybowski in Siberia, said 

 to belong to this species, and stated that they were very similar to 

 those of the Common Fieldfare. More recently Mr. Dresser has had 

 the best of all reasons for doubting the above eggs, by seeing the 

 real one in the collection of Mr. Swinhoe. This gentleman has kindly 

 offered me a specimen to illustrate this work. As Mr. Dresser observes, 

 it is more like the e^^ of the Missel Thrush, or rather some of the 

 varieties of the Ring Ouzel, than the Fieldfare.
