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. Journ. 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. derbianus 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 Tyrannide 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, Ist = 8th; tail moderate, square, < $ wing, tarsus = $ wing.
