BIRDS OF UPPER PEGU 141 



from Darjeelingas albigularis (Proceedings, Zoological Society, 

 1861, p. 200), and this latter name having- been forestalled, again 

 described by Jerdon, in 1863, in his Birds of India, Vol. II, p. 

 203, as flaviventris. Neither of the descriptions appear to me 

 altogether correct. In the original one it is said that the 

 cap is light ashy ; in Jerdon's, that the head is greyish ; but in 

 none of the specimens that I have seen has more than the fore- 

 head and anterior half of the crown been grey ; the posterior 

 half of the crown and occiput are always concolorous with the 

 back. Again, Jerdon says that the lores are black; but they are 

 not black, they only have a dusky stripe running through them ; 

 not merely are the chin and throat white, but so also is the upper 

 margin of the breast. The whole of the cheeks and ear coverts 

 are greyish white, only the extreme tips of the latter are 

 sometimes faintly tinged with green. There is in good speci- 

 mens a dusky spot behind the eye, and the ear coverts are some- 

 times greyish brown instead of greyish white. 



Mr. Oates remarks : " This species does not appear to me to 

 be common. I have only met with it on the western side 

 of the hills — in nullahs, amongst brushwood. The birds vary 

 a good deal in size. Two specimens, the smaller, perhaps 

 a female, though I did not ascertain the sex, measured as 

 follows : — 



"Length, 4, 4'4; expanse, 5*6, 6 ; tail, from vent, 1*55, 

 1*8; wing, 1*72, 1'92; bill, from gape, 0'55, 057 ; tarsus, 

 0-71, 0-78. 



" The bill is a more or less dark brown above, paler and more ov 

 less plumbeous on the lower mandible ; the inside of the mouth, 

 yellow, or pale orange, fleshy ; the irides, dark brown ; eyelids, 

 grey or plumbeous ; legs, dusky or fleshy yellow." 



585. — Enicurus immaculatus, Sodgs. 



Thayetmyo specimens are identical with others from Sikhim. 

 A very little further south-east this species is entirely replaced 

 by Leschenaultii, V. 



Mr. Oates says : ' ' The Spotless Fork-tail is common in all the 

 hill streams, but not in the plains, where I have never seen it. 

 It appears to be equally common in the Arracan Hills. It has 

 rather a pretty song which it sings off a bush. A male 

 measured — 



"Length, 9*8; expanse, 12*5; tail, from vent, 53; wing, 

 4; bill, from gape, - 95; tarsus, 1*22. 



" Birds from the Arracan Hills seem to be slightly 

 smaller. 



" The irides are brown ; eyelids, well-feathered ; bill and inside 

 of mouth, black ; feet and claws, pale yellow/-'
