defined on sides of breast; under wing-eoverts and broad edges to inner 

 webs of reraiges buff. Upper mandible black ; lower, pale yellowish 

 brown, tipped with black; feet liorn color; iris carnune. This color 

 from life, the others from dried skin. Wing, 3.30; tail, 2.05 lateral 

 feather 0.80 shorter; exposed culmen, 0.95; tarsus, 0.65. 



Mr. Eidgway's notes on the bird, made before knowing the circum- 

 stances under which it was shot, however, are as follows: 



It i.s conspicuously unlike any of the twenty-three specimens of M. imnamensis 

 with which it has heen carefully and simultaneously compared, nowithstanding the 

 range of individual variation is so great. It M. iiwrnaia, as defined by Sclater and 

 others, is separable from M. panamnt-sis, then M. fulvjinosa is certainly very dis- 

 tinct from both. The only other view which can possibly be justified by the series 

 before me is that there is only one species in Central America, from Piiniuna to 

 Guatemala, varying individually in i)]umage to a remarkable degree. Should this 

 view prove correct, then M. fiiHijhioaK must be jidniitted to represent an extreme of 

 coloration (luito as marked as the rufescent birds which occur both at the northern 

 and southern limits of this range. 



167. Bucco dysoni Scl. 



One sjtecimen (detained in the forest on the Escondido. Tliis indi- 

 vidual was catching insects, and acted very much like a Tyrannus. 

 On making a capture it would seek a new perch, flying in a leisurely 

 Avay, find showing considerable hesitancy about selecting a i^lace to 

 settle upon. 



Iris, wine-purple; bill, black; feet, blackish. 



Family TKOGONID^. 

 168. Trogon caligatus Gould. 



Apparently uncommon, on the Escondido, where all Tr<^gons are 

 called "Mountain Parrots'' by the Engiish-vspeaking jteople. Orbital 

 ring yellow. 



169. Trogon atricollLs tenellus (Cab.). 



Common. Oiu' flew into the house. Trogons are almost invariably 

 found in ]>airs, rarely in small flocks. Iris very dark brown; feet 

 plumbeous; orbital ling blue; bill chromium-green. 



170. Trogon chrysomelas sp. uov. 



Sr. Char. — Pjxactly like T. (itrimllis tcnelln.s, except tiuit the jnetal- 

 lic green of the male is wholly replaced l)y opaque black, without the 

 slightest trace of metallic gloss. 



Adult male (Type, No. 127338, Escondido Eiver, Nicaragua, Septem- 

 ber 23, 1892; Chas. W. Eichmond): Entire head, neck, and chest uni- 

 form "dead" black; back, scapulars, and rump dull, dusky grayish 

 brown, tinged or mixed with blackish; upper tail-coverts and middle 

 tail-feathers brownish black, th.e latter abruptly tipped with deep black 

 (about 0.10 of an inch wide). Wing-coverts and outer surface of closed
