As already noticed, it is really only by this black patch that
the present species is distinguished from the Tenasserim race of
the Rufous-throated Hill Partridge. Now, in both this race
and the Himalayan one, specimens occur in which the black
spots on the throat are large and almost coalesce in some places ;
and in our present species, the black throat patch is at times
small and dotted with pale ferruginous, showing that it is
nothing but coalesced spots, and I am inclined to think that
those who do not separate the Tenasserim race should equally
refuse to separate the present one.
