434 REVIEW OF AMERICAN BIRDS. [PART I. 
not attenuated. Tail emarginated, and still more rounded. Bill rather stout, 
and somewhat Thrush-like; broad, much depressed, and with mouth deeply 
cleft, much as in Alyiadestes, but deeper and stouter in proportion. Gonys 
about two-fifths the lower edge of lower mandible. Frontal and rictal bristles 
well developed. Feet short; tarsus about equal to middle toe, without scu- - 
tellar division, excepting two plates at lower end, both sides of which also 
exhibit slight indication of similar division. Lateral toes about equal, their 
claws reaching to base of middle claw. Basal phalanx of middle toe united 
for a very little more than half to rather less than half the basal phalanx 
of inner toe, and for two-thirds its length to one and a half joints of outer: 
this phalanx a little shorter than the basal of inner toe. 
The relationship of this genus to Myiadestes is very close, and 
‘seems to connect the group with the Turdidx. The body is fuller; 
the basal joints of the middle toes a very little more united; the 
bill stouter, stronger, and deeper; the plumage more compact, and 
the wing lacks the peculiar pattern across the base and outer edges 
of the quills, having instead the lighter rusty edgings at the base 
inside, so common in the Turdide. The outer quills lack the 
attenuation of typical Myiadestes, but resemble almost exactly those 
of M. unicolor. In fact the only tangible differences are in the 
stouter bill, rather more united toes, more compact plumage, and 
absence of wing pattern. 
Dr. Cabanis gives, as one of the characters of Cichlopsis, the 
tarsi distinctly scutellate. In Dr. Sclater’s specimen, however, the 
tarsi are as much booted as in the genuine Thrushes. The basal 
joints of the middle toe are united a very little more than in Turdide ; 
but, on the other hand, in Myiadestes proper, these are as deeply 
cleft as in the Thrushes. 
The young of Cichlopsis are probably pte Fi as in Myiadestes, 
judging from the indications of the adult.

(No. 291a, Sclater Coll.) Wing rather longer than tail, which is moderately 
emarginated and still more graduated ; the feathers broad. First quill about 
two-fifths the 2d, not quite one-third the longest (4th and 5th); 2d inter-
