CICHLOPSIS. 435 
mediate between 6th and 7th; 3d between 5th and 6th, the feathers broad ; 
the Ist primary slightly falcate, but not attenuated. Tarsi with two scutellar 
divisions only anteriorly at lower end, as in other Myiadestes, the upper 
indistinct. 
Whole upper parts, with head all round, and upper part of breast, oliva- 
ceous-rufous (without any shade of green) ; lighter below, but brighter on 
throat ; rest of under parts ashy ; the flanks, lower breast, crissum, and tibia 
tinged with olive rufous. Tail like back; the central feathers and inner 
webs of the others with a purple tinge; the lateral paler on inner edge and 
at tip. Under wing coverts fulvous white; the basal portion of inner webs 
of quills (but not outer) pale cinnamon, fading off gradually along the edges 
of the quills, rest of these webs purplish-brown ; whole of outer webs of quills 
like back, without any bars. Bill above black, beneath whitish; legs dusky. 
(No. 29la.) Total length, 8.00; wing, 4.20; tail, 4.00, graduation, .34, 
emargination, .20; difference of 10th and longest quills, .91; exposed portion 
of Ist primary, 1.14, of 2d, 2.75, of longest (5th) (measured from exposed 
base of Ist primary), 3.20; length of bill from forehead, .70, from nostril, .35, 
along gape, .85; tarsus, .90; middle toe and claw, .86, claw alone, .26; hind 
toe and claw, .55, claw alone, .25. f 
This species is closely related in form to Platycichla brevipes, 
Baird, although the lower mandible is rather deeper and stouter, 
the upper less attenuated viewed from above. ‘The first quill is’ 
longer, two-fifths the second instead of one-third, and not quite as 
much pointed; the tail is more graduated and emarginated ; the 
feet much the same. The principal difference, therefore, is in the 
stouter lower mandible, and less attenuated bill, longer first pri- 
mary, and more emarginate and graduated tail. 
From Myiadestes armillatus it differs in stiffer tail and falcate 
acuminate outer primary. With such species, however, as J. 
obscurus and venezuelensis, it has very close relationships in form, 
so much indeed that it is very difficult.to separate them generically ; 
the tail feathers are perhaps broader and stiffer, and the bill rather 
longer and stronger; the wings and feet are precisely similar. 
The two citations from Lesson, quoted in the synonymy, by Dr. 
Sclater, hardly appear to belong to this species, but rather to an 
allied one. The description in “J’Echo” I have not seen, that in 
“ Desc. des Mam. et Otis.” shows many discrepancies. 
For the opportunity of examining this species I am indebted to 
Dr. Sclater. I have’seen a second specimen in the museum of the 
Philadelphia Academy.
