Prionoteles (emendation) ScuaTEeR and Satvin, Nom. Av. Neotr., 1873, 103. 
Rather small Trogons agreeing with Temnotrogon in filamentous 
auricular feathers, slight extent of cohesion of anterior toes, and 
similarity of sexes in coloration, but differing conspicuously in form 
of middle rectrices (which are concavely incised and laterally pointed 
terminally) and in conspicuous white subterminal spots on outer 
webs of secondaries. 
Bill rather stout but broader than deep basally, the culmen moder- 
ately arched, rounded (not ridged), the gonys about as long as man- 
dibular rami, distinctly convex, strongly ascending terminally, the 
tip of mandible forming a distinct but small ascending point; basal 
width of interramal space about equal to its length; tomia distinctly 
serrate. Nostril roundish, non-operculate, concealed, or nearly so, 
by antrorse, decurved bristles. Feathering of head normal, except 
auricular feathers, which have elongated, filamentous tips, curved 
outward; feathers of chin and malar apex bristle-like, antrorse, the 
former strongly recurved; seventh, or seventh and sixth primaries 
longest, the tenth (outermost) less than half as long as eighth; tail 
longer than wing, the eight middle rectrices with tip strongly con- 
cavely incised, with web on each side of the excision expanded and 
prolonged into sub-falcate points, the two lateral pairs with tip 
obliquely truncate or subtruncate, with inner web longest and usually 
(at least in adult males) forming a blunt or rounded point. Tarsus 
longer than longest anterior toe (without claw), naked for lower 
half or more; anterior toes united for basal phalanx only. 
Coloration.—Pileum dark metallic violet-blue to greenish blue, 
passing into black on sides of head; rest of upper parts except remiges 
and lateral rectrices metallic green, more bluish on rump and upper 
tail-coverts; remiges spotted with white, the lateral rectrices exten- 
sively white terminally; anterior under parts, as far backward as 
middle of abdomen, light gray (the throat more whitish), posterior 
under parts red. (Sexes alike.) 
Range.—Island of Cuba, Greater Antilles. (Monotypic.)
