receptacles, very bushy in appearance. My specimens are not 
more than 14 inches long, but evidently indicate a plant 2 or 
3 feet in length.

XXX.—Descriptions of two new Birds from Jamaica. 
By Puitie Henry Gosse. 
Tae former of the two species which I am about te describe was 
accidentally overlooked in writing my ‘ Birds of Jamaica,’ and the 
latter has been discovered since the publication of that work. 
Elania cotta. Uength 51 inches, expanse of wing 8,5,, flexure 
2,55, rictus 13, tarsus ;8,, middle toe 55. rides dark hazel ; feet 
dark slate-gray; beak black. Head blackish ash; crown bril- 
liant yellow, commonly concealed; back and rump olive; tail 
blackish with olive edges; wing black; the primaries edged 
faintly, the secondaries, tertiaries and greater coverts conspicu- 
ously, with pale yellow; third quill longest. A white stripe, 
ill-defined, over the eye, meeting on the forehead ; ear-coverts 
white, with dark tips; chin, cheeks, throat, and breast white, 
speckled obscurely with black beneath the eyes; belly, vent, 
under tail-coverts, and inner surface of wings, delicate pale 
yellow. | 
This little Tyrant, for want of any obvious peculiarities to di- 
stinguish it from others of its genus, I have named from the 
locality where I first met with it, the Cotta-wood, a tangled cop- — 
pice on Grand Vale Mountain, in the parish of St. Ehzabeth. I 
afterwards observed it in other situations, as in the woods around 
Bluefields, but it does not appear to be anywhere common: nor 
am I able to say whether it is a permanent resident, or merely a
