940 Mr. BlytKs Report for December Meeting, 1842. [No. 143. 



3. M. melanoleuca, Nobis, Hodgson. Length four inches and a , 

 half, of wing two inches and a quarter to two and three-eighths, 

 and tail an inch and seven-eighths; bill to gape nine-sixteenths of 

 an inch, and tarse half an inch. Colour wholly black and white : the 

 upper-parts black, with a broad white eye-streak, and broad longi- 

 tudinal mark of the same upon the wings, commencing on the coverts 

 of the secondaries and continued along the margin of the tertiaries, 

 which in some are further edged with white round their tips ; under- 

 pays also white, and basal half or more of the outer tail-feathers. 

 Bill and feet black. Nepal, Darjeeling. 



4. M. rubecula, Nobis ; Dimorpha super ciliaris, Nobis, J. A. S. 

 XI, 190, which specific name must now be transferred to the second 

 species. Nepal, Darjeeling. 



Of true Dimorpha, Hodgson, I know of only two species; viz. 



1. D. strophiata, Hodgson, upon which the group was founded: 

 and 



2. D. auricularis ; Chaitaris auricularis, Hodgson, M. S : which 

 has the ccerulean spot on the sides of the neck common to the species of 

 restricted Chaitaris, but the rest of its plumage is plain dull olive, 

 rufescent on the wings and tail, and slightly on the rump, the under- 

 pays paler and inclining to whitish on the belly. Length about five 

 inches, of wing two inches and a half, and tail two inches ; bill to 

 gape nine-sixteenths of an inch, and tarse five-eighths of an inch. 

 Inhabits Nepal and Assam. 



Very closely allied to these is the Muscicapa leucura, Gm., the 

 adult male of which is Saxicola rubeculoides of Sykes : but Mr. 

 Hodgson makes a separate group of it, though it scarcely differs except 

 in having the first primary less developed and the second more so. 



Of true Chaitaris, I know of three species ; viz. 



1. Ch. grandis, Nobis, J. A. S. XI, 189. Common at Darjeeling. 



2. Ch. sundara, Hodgson, Ind. Rev. 1837, p. 651. Also common 

 at Darjeeling and in Nepal : and 



3. Ch. McGregorii ; Phcenicura McGregor ii f Burton, P. Z. S. 

 1835, p. 152; Ch.fuligiventer, Hodgson. Himalaya. The following 

 species I separate by the appellation 



Cyornisy Nobis: having the bill less compressed, the tarsi shorter 

 and together with the toes more feeble, and altogether partaking more
