400 RECENTLY-DESCRIBED SPECIES. 



Legs pale grey with green tinge ; bill pale horny-black, pale 

 beneath ; irides dark brown. 



Length, 14*5; wing,6'25; tail,5'0; tarsus, 2*1 ; bill at front, 0*9. 



Through the kindness of Dr. J. Anderson, I have examined 

 a specimen of B. Fytchii % from the Yunan Hills, and with 

 this the Khasi bird is evidently very closely allied, if 

 indeed it should not turn out to be identical ; but between my 

 bird and B. Fytchii there are differences which, though perhaps 

 small, separate them, and until birds of the same sex are placed 

 side by side, we cannot well decide whether they are two good 

 species or not. To begin the enumeration of the points of 

 difference, the Yunan bird (A) is much smaller than the Khasi 

 one (B) : 



(A) B. Fytchii, tarsus, 1*7 ; mid-toe, 1*7. 



(B) B. Hopkinsoni, tarsus, 2'1 ; mid-toe, 2*1. 



In (B) the feathers on the flanks have the black terminal spot 

 invariably heart-shaped, whereas in (A $ ) the correspond- 

 ing feather is a diamond form {vide also the figure of J in P. 

 Z. S., 1871, PI. XI. 



In (A) the whole of the lower back is plain olivaceous, with 

 a few of the longest upper tail-coverts having a black triangu- 

 lar (isosceles-shaped) terminal spot, followed by a white base. 



In (B) these spots are much larger and broader, and extend 

 up over the rump, aud the feathers are more distinctly barred 

 with brown and have a rufous tinge at the base. 



In (B), and I think this is the most important difference, all 

 the feathers of the upper back are spotted with white, and this 

 feature extends to the wing-coverts and shoulder of wing. In 

 (A) there is no tendency to this coloration, nor is there any trace 

 of it in the plate in the P. Z. 8. 



(A) is dark brown on chin ; (B) very pale. 



(A) tail not distinctly barred; (B) tail well barred and the 

 pale bars edged with black. 



(A.) tail beneath dull brown; (B.) tail ruddy brown. 



However, whether they be separable or not, and a larger 

 series will decide this, one important point is finding this bird 

 so far to the westward ; within Iudiau limits, it has never before 

 been recorded. My specimen was shot at Shillong on grassy- 

 slopes at 5,000 feet. Before I had seen the bird in hand, I had 

 twice seen it running on the pathway, aud noticed its very differ- 

 ent flight from that of the Black Partridge, which at first I 

 thought it was. Now that attention is called to it, other speci- 

 mens will no doubt turn up. 



Next follow a number of species described by Lord Walden, 

 for the most part the results of Lieutenant Wardlaw Ramsay's 

 explorations in North-Eastern Burmah.
