spelcea, but I scarcely think that it merits specific 
separation. 
In this present species or race (C. neglecta) the wings of 
the female average about 8*5, and of the males 8*75, being 
an inch shorter than the recorded measurements of C. livia. 
Moreover, according to Macgillivray^s description^ the whole 
back of C. livia from near the shoulders to near the tail is 
pure white, whereas in this species the band of pure white 
across the lower back never exceeds 1'35, and in some 
specimens is scarcely above an inch in extent. The whole 
rump, upper tail- coverts and basal portion of the tail is a 
very deep slaty grey, contrasting very strongly with the 
white of the lower back. In the intermediate form the 
white is more or less tinged with grey, and the con- 
spicuously white portion of the back does not exceed half 
an inch in breadth.

One specimen of this species was procured at Le on 
the 4th July, where enormous flocks of Pigeons were 
observed, but it was not at the time discriminated, and it is 
not certain whether these colonies consisted entirely of this 
species, or whether other species were intermingled in the 
flock. [G. H.] 
The description given by Major Boys, and quoted by Dr. 
Jerdon (vol. iii. p. 470), is excessively accurate, except that 
he fails to notice the deep vinaceous purple tinge which 
extends over the greater portion of the breast. The bird is 
considerably larger than C. intermedia, and much paler in 
colour ; the specimen obtained measured 14*0 in length, 
wing 8 5, tail 5'5, tarsus I S, mid toe to root of claw 1-06, 
its claw straight from root to point 0*4, bill at front 0*63, 
bill from gape 0 82. The white band on the tail feathers 
is about 1*15 broad on the centre tail feathers, and below 
this band the black slaty tint extends for about 1*2 ; on the 
outer tail-feathers the white band is nearly 1*4 wide, and
