its greyer head and the absence of the white superciliary stripe so conspicuous in both 

 the allied forms. 



Its range is restricted to the western portions of the South-American continent from 

 Peru northwards; the limit of its range in this direction being Nicaragua, where 

 Mr. Nutting speaks of it as abundant at Sucuya *. 



PITANGUS. 



Pitangus, Swainson, Zool. Jonrn. iii. p. 165 (1827) ; Scl. Cat. Birds Brit. Mus. xiv. p. 174. 



This genus contains ten species, if we include the abnormal P. parvus, Pelz., which 

 is perhaps more naturally placed in Megarhynchus. These are distributed over the 

 greater part of the Neotropical Region from Northern Mexico to the Argentine 

 Republic, a section of the genus with white under surface being well represented by 

 four species in the Bahamas and West-Indian Islands. In our region P. deriianus is 

 the only one which is nearly universally spread ; but in the State of Panama the 

 southern P. lictor occurs, and there also P. albovittatus is found, a little known. species 

 not hitherto noticed elsewhere. 



Pitangus belongs to the group of Tyrannidee which has the supranasal feathers 

 elongated, extending over the maxilla so as to completely cover the nostrils ; the latter 

 are open and nearly circular, and without any overhanging membrane ; the bill itself 

 is very strong, the culmen slightly decurved and terminating in a prominent hook, the 

 sides of the bill are nearly straight, converging gradually from the gape to the tip, the 

 width at the gape is considerably less than half the length of the tomia, the rictal 

 bristles are well developed ; the tarsi are short but strong, and the toes strong, the 

 middle toe long, the lateral ones short and subequal ; the 3rd and 4th quills are equal 

 and longest, 5th > 2nd, 1st = 8th ; tail moderate, square, < f wing, tarsus = \ wing.
