318 DR. O. FINSCH ON BIRDS FROM NORTH-EASTERN 
of the head and throat; besides, in A. gularis the naked portion of the: tibia is con- 
stantly further extended (21-31", in A. sacra 12-18"). By this latter character the 
white specimens of both species are also distinguishable. 
P. 297. no 198; ARDEA ATRICAPILLA. 
The Rev. H. B. Tristram concurs in Mr. Gurney’s opinion (Ibis, 1869, p. 437) that 
A. javanica, Horsf., is inseparable from A. atricapilla, adopting the views of Dr. von 
Schrenk, who several years ago (Vogel des Amurlandes, pp. 437-447) maintained that 
all the members of the subgroup Butorides (A. virescens, Gmel., of North America, 
A. scapularis, Ill., of South America, and two species mentioned before) belong only to 
one species. Notwithstanding their near relationship, I must declare my own belief 
that they are different species, of as much value as many others. In respect to the 
Indian and African species, I find that 4. atricapilia is always distinguishable from 
A. javanica in having the middle line along the fore part of the neck always tinged 
with fulvous, whereas in 4. javanica this portion is uniformly greyish like the other 
parts of the neck and body. Occasionally a faint tinge of pale fulvous is seen in very 
old specimens of 4. javanica. A full account of the differences of these two species 
will be found in our ‘ Ornithologie der Viti, Samoa and Tonga Inseln,’ p. 210, and ‘ Vogel 
Ostafricas,’ p. 703.
