OF THE ANDAMAN ISLANDS. 289 
to the Malayan or Himalayan forms. Lord Walden has recent- 
ly remarked (Trans, Z. S. IX. 2, p. 180) that the Malayan race 
is LEdolius afinis, Blyth (J. A. S. B., 1842, p. 174,) the 
Himalayan D. annectans, Hodgs. (Ind. Rev., 1837, p. 326), and 
that he is unable to separate the two. 
280 d:s.—Dicrurus leucogenys, Walden. 
I entered a young specimen of this species erroneously as 
leucopheus, Vieill; the latter is considered to be exclusively a 
Javan form, and though when adult closely resembling the young 
of the present species before the white cheeks of the latter 
make their appearance, it is a smaller bird, and has the lores 
dark, whereas the young of the present species has them pale 
or almost white. It is the young of the present species that 
Blyth described as cineraceus, Horsf., in his description which 
T quoted, note p. 210, Vol. II. 
356 bis.—Geocichla albogularis, Blyth. 
At page 495, Vol. II, I noticed that Lord Walden had se- 
parated the Andaman Bush Thrush as G. andamanensis, and as, 
though without explaining wherein the difference consisted, His 
Lordship asserted that it was clear that the Andaman bird _be- 
longed to a totally distinct species, I naturally, having no Nico- 
bar specimens to compare, accepted this verdict. 
Having now, however, eleven specimens of the Andaman, and 
four of the Nicobar birds before me, I confess that I should be 
glad to have pointed out to me wherein this total distinctness 
consists ; to me the birds do not appear to be separable. 
First, as to size; the following are the dimensions of the 
wings of my fifteen specimens :—

Then as to color; this is apparently very variable ; no doubt, ~ 
four out of the six Andaman males have duller colored heads 
and are paler below and have less white on the throat (in fact, 
one has no white at all on the throat), than the Nicobar males ;
