Cyphorinus lawrencii. 
Cyphorinus cantans, Lawr. Ann. N. Y. Lye. VII, 293 (not of Casanis). 
Cyphorinus lawrencii, Sct. MSS. Lawrence, Ann. N, Y. Lye. VIII, 1843, 
no. 373. 
Hab. Isthmus of Panama. 
Above reddish-olive, the feathers very obsoletely, almost unappreciably, 
streaked and waved with dusky. Exposed surface of wing and tail barred 
distinctly with black. Feathers of forehead tinged with reddish at base. 
Chin, ears, throat, and upper part of jugulum brownish-red; rest of under 
parts grayish-olive, tinged on the sides and crissum with rufous. Lining of 
wing like throat, but paler. The angle of the chin and the side of the lower 
jaw dusky. A female specimen is similar, but smaller, and lighter on the 
middle of the belly. 
Total length, 5.00; wing, 2.50; tail, 1.55; length of bill from forehead, .90, 
from nostril, .60; along gape, 1.04; tarsus, 1.00; middle toe and claw, .93; 
hind toe and claw, .72; claw alone, .35. 
This species was first referred by Mr. Lawrence to C. cantans (= 
musicus), but on sending specimens to Dr, Sclater, this gentleman 
decided them to belong to a new species which he named C. law- 
rencit. C. musicus (Cayenne) differs in having the breast and belly 
yellowish-white; the ears streaked with black and white (Bur- 
meister). C. modulator (Peru, etc.) is more like it, but much larger, 
and has the rufous of throat extending further down the body, and 
passing into whitish.

MICROCERCULUS, Scnarter. 
Microcerculus, Scuater, Catal. Am. Birds,1861,19. (Type Turdus bambla, Bopp.) 
General appearance of Cyphorinus, the tail still shorter, in type less than 
half the wings, the feathers soft; the end of outstretched tibia reaching the 
tip of tail. Bill compressed ; the height about one-fourth the length ; culmen 
nearly straight, not angulated or gibbeus at base ; tip notched, quite abruptly 
decurved. Nostrils apparently double, or with two openings on each side.
