" The numerous specimens of Eollers from Assam, Arracan, and 
Tenasserim, which I have seen," says Mr. Blyth, "all pertain 
strictly to this species, having the upper parts greener than in C. 
indica, the neck and breast devoid of the reddish -brown colour 
proper to the latter species, being purplish-dusky varied with bright 
purple on the foreneck, and the entire under-surface of the wing, 
except near the tips of the primaries, is deep purple ; but I have 
obtained several specimens in the vicinity of Calcutta, and some 
from Tipperah, which present every gradation of plumage from one to 
the other of these species, and also some in the pure affinis plumage ; 
from which I infer, that where found together in the same locality, 
they not unfrequently interbreed, and tend to merge into a single 
blended race. It may be further remarked, that I have never seen 
an example of true C. affinis with the broad terminal purple band to 
the tail, which distinguishes the adult of C. indica ; but I have seen 
this imperfectly developed in the mixed race, which latter has also 
commonly the forepart of the under-surface of the wing intermingled 
purple and verditer." 
F. Buchanan Hamilton, in his MS., mentions, that " this bird is 
very common at Gualpara throughout the year ; the natives con- 
sidering it as distinct from the Nil-khant."
