44 MAJOR H. H. GODWIN-AUSTEN ON NEW [Jan. 6, 



Walden, and the great use his fine collection has proved in the 

 correct determination of so many of the birds I obtained. 



Several birds from the same part of India yet remain to be 

 identified ; and I may mention the discovery of a Bambusicola, 

 allied to B.fytchii, Anderson, with which my specimen agrees very 

 closely, but the dimensions differ much. Thus : — 



Length. Wing. Tail. Tarsus. Bill at front, 

 in. in. in. in. in. 



Yunan bird .... 12-0 5-8 4-2 1-58 0-86 



Khasi bird .... 14-5 6-25 5-0 1-2 0-90 



If this should prove distinct on comparison of the specimens, I propose 

 to name it B. hopkinsoni, after the able officer so long the Com- 

 missioner of Assam, and who took so great an interest in our survey 

 operations. 



The presence of this bird so far west, even if it should prove 

 identical with Anderson's bird, is a point of very great interest in 

 the distribution of some of the forms from Western China. 



Cypselus subfurcatus, Blyth, identical with specimens from Amoy 

 and Malacca, I also found breeding at Shillong in June, in the 

 precipices that bound the Umiam valley — Cypselus infumatus, Sclater 

 (tectorum of Jerdon), being another Swift having an equally extended 

 range and discovered about the same time ; and the presence of other 

 genera on this elevated promontory of the Garo, Klnisi, and Naga 

 Hills, south of the alluvial valley of the Brahmaputra, marks most 

 distinctly the extreme limit of the very marked Indo-Chinese and 

 Malayan fauna, across which narrow belt many do not extend. 



SlTTA NAGAENSIS, 11. Sp. 



Description. — Above slaty blue, palest on neck and head ; two 

 centre tail-feathers, shoulder of wing, and secondaries same colour 

 rather brighter ; quills brown-black ; outer tail-feathers black, with a 

 white patch on the inner web of the four outer, increasing outwards 

 and in the outermost extending diagonally to the other web, all tipped 

 grey and terminating in black ; a black streak from lores through eye 

 to ear-coverts and down side of neck. Beneath dull sordid white, 

 purer on chin and throat, with a few white feathers bounding the 

 ear-coverts ; flanks, thighs, and under tail-coverts rusty chestnut, all 

 the latter with a terminal white spot. 



Bill black above, grey below ; legs greenish black ; hides dark 

 brown. 



Length 4*9 inches, wing 3'0, tail 1*75, tarsus - 68, bill at front 

 0-58, extent of foot 1'2. 



Inhabits the Naga Hill-ranges, and was not uncommon. 



Garrulax galbanus, n. sp. (Plate X.) 



Description. — Above pale pure olivaceous on head, with a brown 

 tinge on the back ; tail pale ashy brown ; the four central feathers 

 tipped umber-brown and barred ; the four outer of the same colour in 

 middle and broadly tipped with white ; wing concolorous with
