principalis (Hurtl.). One. Interior of Cayenne. 
The specimen labelled as above has been identified as this species at the British 
Museum. In the original Catalogue of Lord Derby’s Collection, it has the same 
register number as specimens of Leptoptila jamaicensis. It very nearly agrees 
with the description of Co/umba erythrothorax, Temm. & Knip., from Surinam, a 
species which has not hitherto been identified, but the under tail-coverts are 
hoary grey, not cinnamonas in that species. Count Salvadori was not acquainted 
with the species, which, however, is very distinct, distinguished from H. simples, 
by its more rufous breast, and from all other species of the genus by its white 
under tail-coverts. ;

‘* Forehead and crown to line between middle of orbits, pale creamy drab, shading 
abruptly into purplish iridescence, which overlies the remainder of crown and 
back of neck. This purplish iridescence on the neck ends abruptly just in 
front of shoulders, and is bordered by a narrow band of feathers tipped with 
greenish iridescence. Entire dorsal surface, including wings and middle pair of 
tail feathers brown, with an olive wash, except on tail and upper tail-coverts. 
Throat distinctly whitish, remainder of lower side of neck, and thence back over 
chest, delicate creamy lilac ; abdomen and under tail-coverts white, with a pale 
wash of buffy brown on edges of some of the feathers ; flanks dull butfy-brown ; 
tail feathers—except middle pair—blackish, tipped with white, this tipping 
broadest on outer pair of feathers; under tail-coverts and axillars pale cinnamon.

‘* Back, rump, upper tail-coverts, central tail feathers, tertiaries and wing-coverts, 
greyish olive; primaries and secondaries (especially at tips), blackish brown, 
the former (except first) with more or less narrow whitish edges ; tail feathers 
black, four outer pairs tipped with white, narrowly on the inner one, but increas- 
ing toward the outer pair, on which the white tip is one-half inch broad ; outer | 
web of outer tail feather narrowly edged with white for its exposed portion, 
outer web of outer tail feathers except last mostly greyish olive. Forehead, lores, 
cheeks, ear-coverts, and lower throat ecru-drab, passing into pale vinaceous on 
breast and sides of neck and becoming lighter again on lower breast ; chin and 
centre of throat white; centre of crown distinctly french grey, passing 
posteriorly into dull plumbeous mixed with vinaceous on hind-neck, the feathers 
on sides of occiput, hind-neck, and slightly on sides of neck rather sparingly 
glossed with purple, and on lower part of hind-neck with green. Centre of 
abdomen and under tail-coverts white ; sides of body brownish buff, darker on 
flanks; axillaries, under wing-coverts, and most of underside of primaries, 
chestnut ; first primary only narrowly edged with chestnut on inner web. 
Wing, 5°07 ; tail, 4; tarsus, 1:01 ; exposed culmen, 0°66 inches. This specimen 
is the only one of the four represented in the species in which the centre of the 
crown is of a pronounced greyish colour, but the others have a trace of it, some- 
what masked by the vinaceous tinge of the surrounding parts. The other 
specimens have the inner web of the first primary mostly chestnut, instead of a 
narrow edging asin the Type. This species is closely related to L. verreausi, 
but is smaller, greyer above, with metallic colours on hind neck, occiput; and 
sides of neck less pronounced. Trinidad and Tobago birds resemble the 
Margarita form in size, but the colours are more like true L. verreauxi. Three 
other specimens of L. insularis measure :— Male adu/t—Wing, 5°25 ; tail, 4:15: 
tarsus, 1:07 ; culmen, 0°68 inches. Female adult—Wing, 5°27 ; tail, 4°08 ; tarsus, 
1:07 ; culmen, 0°67 inches. Female aduwlt— Wing, 5°23; tail, 4:10; tarsus, 1; 
culmen, 0°64 inches.” (Richmond). Habitat. Margarita Island.
