Show 1880.] MR. R. TRIMEN ON A NEW ROLLER. 31 me to select for the museum a small series of the rarer species represented ; and amongst these is a single specimen of a Roller which appears to be very distinct from any of the described species. I give tbe following description of this interestina* new form, and will append to it the notes on the bird which have been kindly furnished to m e by the discoverer. CORACIAS SPATULATUS, sp. nov. d. Forehead and superciliary stripe rather broadly white ; top of head, neck, and back dull pale greyish-green mixed with cinnamon-brown, the latter colour predominating on the scapulars and lower part of the back ; rump and upper tail-coverts ultramarine-blue, the coverts richer and deeper in colour ; chin and a spot at base of lower mandible whitish; throat, breast, belly, thighs, and under wing- and tail-coverts pale bright verditer-blue, varied on the lower throat and breast by lilacine cinnamon-brown webs, leaving the shaft-stripes of the blue; cheeks and ear-coverts mixed lilac and verditer-blue ; sides of neck coloured like the back ; sides of breast dull sandy-brownish with bluish-white shaft-stripes ; upper wing-coverts ultramarine, except a short central band of cinnamon-brown lesser coverts, which is edged on both sides by a few ferruginous-violaceous feathers; primaries black on inner webs, ultramarine-blue on outer webs, their basal portion on both webs (but only on the inner web of the first primary) pale bright verditer-blue ; secondaries coloured like the primaries, except the last three, which are cinnamon-brown. Tail forked, the feathers increasing in length from the two middle ones, which are the shortest; the two outermost feathers are prolonged (their inner web being abruptly much narrowed) 2\ inches beyond the next feathers, and their extremity is rather broadly spatulated by the gradual widening of the inner and abrupt widening of the outer web ; these spatulate feathers are light verditer-blue as far as their sudden narrowing, and thence wholly black (including the terminal expansion) ; the next feather on each side is verditer-blue, broadly tipped with blue-glossed black, which extends a good way along the inner web ; the next is similarly coloured, but the dark portion extends much further towards the base ; the following feather is dark-blue throughout, except that its base and a very thin edging of its outer web are verditer-blue; and the two middle feathers are wholly black except for a slight gloss of blue on each side of the shaft; on the underside of the tail the colouring is paler, and the dark parts of the feathers are shot with bluish-green. "Bill black; feet greenish-yellow; iris yellowish-brown" (B. F. Bradshaw). Total length in inches (including long tail-feathers) 15| ; length of culmen \\, of folded wing 6£, of central tail-feathers 5|, of outermost tail-feathers 8^. This fine Roller is in some respects intermediate between its two nearest allies, C. caudatus, L., and C. abyssinicus, Bodd., but is at once distinguished from them both by the spatulate form of the elongated outermost tail-feathers.
