518 APPENDIX I. 



p. 361 ; 588 bis.—Henicurits ruficapillus, Tern. 



Add, streams at base of Nwalabo, being by far the most 

 northern locality at which we have as yet observed this species. 



p. 362; oQlbis.— Motacilla dukhunensis, Sykes. 



From the list of localities excise Pahpoon. The specimen 

 there obtained, as also one specimen obtained at Kedai-Keglay 

 belonging, I find on re-examination, to a different species 

 which must now be entered in our list as 



591 quat. — Motacilla ocularis, Swinh. (2). 



Pahpoon ; Kedai-Keglay. 



My attention was first drawn to this species by Mr. Gates, 

 who sent me a specimen correctly identified from Pegu. On 

 re-examining my series I found that I had already a speci- 

 men from Pegu, and two specimens from Tenasserim. All 

 the rest of my Tenasserim, Assamese and Indian specimens, 

 nearly 150 in number, are true dukhunensis. 



This species belongs to the alba and dukhunensis group, which 

 retains the grey back throughout the year, and not to the group 

 containing lugubris, Tern. 1820. (=yarrellii, Gould), lugens 

 Illiger, apud Schlegel (=japonica, Swinh.) luzoniensis, Scop, 

 apud Auct, vidua, Sund., &c, which get the black back in the 

 summer. 



Mr. Swinhoe originally described this species, Ibis, 1850, 

 55, as follows : — 



" Distinguishable from M. luzoniensis by a permanently 

 grey back, larger size, and a black line running through the 

 eye past the ear-coverts. Length, 7-8 ; wing, 3'7 ; tail, 3*8. 

 On the other hand the bill and head are smaller. 



Blyth originally erroneously identified this species with 

 duJchunensis, and it is with this species that Indian readers will 

 compare it. 



Its plumage is almost identical, but it is a rather larger bird. 

 Wing, 36, 37, 3-75, and the rest in proportion, and it has a 

 distinc t black line running through the lores to the anterior 

 angle of the eye, and backwards from the posterior angle of 

 the eye right over the ear-coverts. No such line will be found 

 in any specimen of dukhunensis, and this line, Mr. Swinhoe 

 tells us, it retains at all seasons. Our specimens were all 

 obtained from November to February, and I cannot therefore 

 speak to this point from my own knowledge. 



p. 363 ; 593 ter. — Budytes cinereocapilla, Savi. 



p. 364 ; 593 quat. — Budytes flava, Lin. 



We obtained both these species in February at Moulmein.
