of the Genus Pomatorhinus. 133 



Above dull olive- greeu ; head above from forehead to nape 

 dark slate-colour ; lores and ear-coverts black, a white super- 

 cilium from nostrils to nape ; throat, breast, and belly pure 

 white ; flanks, sides of the breast, and a patch on each side 

 of the neck behind the ^ear-coverts ferruginous chestnut, the 

 lateral breast-feathers ceatred white ; sides of the abdomen, 

 thighs, and lower tail-coverts dusky olive-green. Spec, descr. 

 ex Darjeeling : mus. Tweeddale. 



Bill orange-yellow, culmen dark brown; irides hoary {Jerd.), 

 purple {God win- Austen) ; legs plumbeous. 



Wing 4*0 in., bill from gape 1-3, tarsus 1-3, tail 4-2 to 4-6. 



In some specimens the head is dull olive -green, only tinged 

 with cinereous. 



Hab. N.W. Himalayas, Nepal, Sikkim, Bootan, Dacca 

 (Jerdon), Assam {Godwin- Austen). 



After a careful examination of a large series of P. schisticeps 

 and the so-called P. leucogaster, from the Himalayas, Garo 

 hills, Munipur, Dafla hills, Naga hills, and Saddya, it seems to 

 me quite impossible to recognize two species. Blyth states 

 (Cat. B. of Burma, 1875, p. 113) that P. leucogaster is smaller 

 than P. schisticeps. I have examined three of Hodgson's 

 Nepal type specimens of P. schisticeps in the British Museum; 

 and these have the wing respectively 4"07, 3*9, and 3"6. 

 Gould, in his description of P. leucogaster, gives the wing as 

 3*75, which is actually longer than in one of the specimens of 

 typical P. schisticeps. 



The race which inhabits Burmah and Karen-nee is more 

 closely allied to P. olivaceus, Blyth, than to P. schisticeps, 

 to which Mr. Hume (S. F. iii. p. 121) refers specimens from 

 Thyetmyo. This race has been separated by Lord Tweed- 

 dale under the title of Pomatorhinus nuchalis {vide infra) . 



5. Pomatorhinus OLIVACEUS. 



Pomatorhinus olivaceus, Blyth, J. A. S. B. xvi. p. 451 

 (1847) ; Hume, S. F. v. p. 137. 



Differs from P. schisticeps in having the upper surface 

 somewhat brighter, the nape faintly tinged with ferruginous, 

 the bill yellow throughout, and by the ferruginous neck-spot 

 not being extended down the sides of the breast and flanks,
