Genus TACHORNIS Gosse. 
Tachornis GossE, Birds Jamaica, 1847, 58. (Type, T. phenicobia Gosse.) 
Small Micropodide (length about 90-100 mm.) with outer and 
middle toes inclined outward, inner toe freely reversible, toes naked, 
and tail forked for much less than half its length, the outermost rec- 
trices not attenuated terminally. 
Outermost (tenth) primary equal to or shorter than eighth, the 
ninth longest, the tenth short-acuminate terminally; tail less than 
half as long as wing, forked for much less than half its length, the 
lateral rectrices not attenuated terminally; tarsus much longer than 
anterior toes, rather stout, feathered in front; middle toe very slightly 
longer than lateral toes, the inner toe freely reversible; toes naked. 
(Unique among Micropodine in character of sternum.*) 
Coloration (of American species).—Above sooty blackish, lighter on 
head and neck; a white patch on each side of rump; throat and abdo- 
men dull whitish, rest of under parts sooty. 
Nidification.—Nest placed within a hollow spathe or attached to 
under side of a frond of a palm tree, composed of feathers and plant- 
down or other soft vegetable fiber (usually down of the Bombazx or 
silk-cotton tree), firmly glued to its support by salivary secretion, the 
materials of the inner portion also densely felted together with the 
same substance. 
KEY TO THE SUBSPECIES OF TACHORNIS PHENICOBIA. 
a. Back black, decidedly darker than pileum; sides nearly black, abruptly contrasted 
with white of abdomen; tail less deeply forked. (Jamaica; Haiti.) 
Tachornis phcenicobia phcenicobia (p. 694). 
aa. Back dark sooty brown, little darker than pileum; sides dark sooty brown, fading 
gradually into (or at least not abruptly contrasted with) white of abdomen; tail 
more deeply forked. (Cuba.)......... Tachornis phoenicobia yradii (p. 695). 
@§o far as known, all Micropodine except Tachornis have the metasternum and 
carina sterni entire; but (according to Gosse, Birds of Jamaica, p. 59) Tachornis pheni- 
cobia has not only two large metasternal foramina, but also has an opening through the 
anterior portion of the keel.
