 Prionotilcs (emendation) Sclater and Salvin, 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, fdamentous 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 ])omt. Tarsus 

 longer than longest anterior toe (without claw), naked for lower 

 half or more; anterior toes united for basal ])halanx only. 



Coloration. — Pileum dark metallic violet-l)lue 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 uj)per 

 tail-coverts; remiges spotted with white, tlie lateral rectrices exten- 

 sively white terminally; anterior imder 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.) 



key to the subspecies of priotelus temnurus. 



a. Larger (male averagint:^: Wing 123.6, tail 116.4, tarsus 16.8, inner anterior toe, 

 15.3, female averaging: Wing 121.8, tail 114.4, tarsus 17, inner anterior toe 15.2); 

 bill relatively smaller and narrower; red of under parts deeper. (Island of Cuba.)
