I am quite of the same opinion as my friends Dr. Jerdon and Dr. 
Stoliczka (J. A. S. B. 1868, p. 43,) as to the difference between this species 
and other Buticillcv, but I rather doubt whether it should be placed m Cln- 
marrliornis, as proposed by Mr. Hodgson and Dr. Stoliczka The bill undoubt- 
edly shews some similarity in form, a modification probably connected with 
aquatic habits of both birds, and the tail is rounded as noticed by er on 
but the wings are B utioilline, and the general characters of the p umage o 
both sexes — structural character which, viewed in the light of evolution y 
descent from common forms, I should be inclined to think of more impor- 
tance than the slight modifications of the bill and tail, -dissociate B fuhgi- 
nosa altogether forms Ohmarrhomi*. It appears to me, as it did to Dr^ 
Jerdon, to form the type of a distinct subgenus which might be called 
Bhyacornis ;* and which appears to me to have as good claims o sepaia ion 
as Adelura and Ohmarrhornis. The characters are : 
Bhyacornis, subg. nov. Ruticilke : Bostrnm brevius et latius qmm - 
cilia,, cauda magi* rotmdata. Fcemina a man valde divena, et rectncibu 
extevioribus basin • vcvsus (ilbis. . .. 
499 B. ( Adelura ) erxtiirooastra (Giild.) — Bill and plumage sum ar 
to Chimarrhomie, but the wings and tail are those of Butictlla, and so aie 
the habits to a great extent. I have seen this bird on the banks ol streams 
and of lakes, but more frequently on rocky hill sides, and at times on the edges 
of glaciers. It was only met with at great elevations, never below 1 > 
but in the highest parts of the Lachen and Lacliung valleys it was iar lorn 
rare, and Captain Elwes shot it at Cholamu Lake. I saw no ema es, k 
I only saw birds in the plumage of the male, and all the specimens s 10 jy 
me were males. , . i n «

B. Vigonii, Moore, quoted by Jerdon as the female of this species, is 
considered distinct by G. B. Gray (Hand-list, I, p. 221). It » certainly very 
different from the bird figured as the female or young male by Gould m the 
Birds of Asia, and as it differs from If. erythrogaster in having the central 
rectriees dark coloured, and in the absence of a wing spot, (both rather impro- 
bable sexual differences), it is probably a distinct species 
500 B ( Chimarrhorn is) leucocephala (Vigors).— Common on streams 
and around the edges of lakes, at elevations above 12,000 feet on the Chola range
