254 REMARKS ON SOME SPECIES OF THE 



of remiges. Tail as back, obscurely barred blackish* 

 feathers of crown edged f black, a few pale spots on sides of 

 occiput; frontals ash, striated black." 



" Auriculars dusky, bounded beneath by a white line, which 

 joins a patch of white on ramus continued to bill ; chin and 

 throat pure white, separated from ramus by a black line which 

 spreads into a patch on side of throat ; from top of eye down 

 sides of neck and across upper back a space of acuminate 

 black-edged white feathers ; all underparts from throat 

 rich orange rusty, deepening into vinous brown on vent." 



I reserve further remarks on this species for our general 

 account of the Birds of Tenasserim. — A. 0. H.] 



gemarfefl on some species of tlje Hitb-jjer.ius fillia, 



)te, 1859.) 



The little sub-group of Swallows, included in Boie's geuus 

 or sub-genus Lillia, presents considerable difficulties to un- 

 learned practical ornithologists, like myself. 



We have apparently four species (excluding hyperythra, 

 which is included by Mr. Gray under Cecropis), but what 

 names two out of these should bear, and whether or no they 

 are distinct and as yet unnamed, are matters that I am uuable 

 to decide with any certainty. 



Mr. Gray, H. L., 69, admits the following species : — 

 L. daurica, L. 

 L. erythropygia, Sykes. 

 L. melanocrissa, liiipp. 

 L. rufula, Tern. 

 L. japonica, Tern, and Schl. 

 L. domicella, Hartl. and Finsch. 

 To which we must certainly add, though Mr. Gray includes 

 the first under Cecropis. 



L. striolata, Tern, and 

 L. arctivitta, Stvi?ih. 

 Now what are our species? 



I may premise that in none of oar four supposed species is 

 there, so far as I can ascertain, ever any white on the inner 

 webs of the tail-feathers. 



Out of some 80 specimens of the smallest of our four species, 

 {erythropygia, Sykes,) I detected in three, small, slightly paler, 



* More correctly " obsoletely banded darker." — Ed., ». F.
