Cypliorimis laiirencii. 



Cyphorimis cantans, Lawr. Ann. N. Y. Lye. VII, 203 (not of Cabanis). 

 Cyphorinus lawrencii, ScL. MSS. Lawkesce, Ann. N. Y. Lye. VIII, 18*J3,

Ilab. Isthmus of Panama. 



Above reddish-olive, the feathers very ohsoletely, almost unappreciahly, 

 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 (:= 

 viusicus), but on sending specimens to Dr. Sclater, this gentleman 

 decided them to belong to a new species which he named C. law- 

 rencii. C. musicus (Cayenne) differs in having the breast and belly 

 yellowish-white ; the ears streaked with black and white (13ur- 

 meister). G. 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.
