 rinca, Fundacion, Santa Marta, and Fonseca. 



This form, originally described by Bonaparte in 1854, was soon af- 

 terwards referred by Sclater to P. grayi of the same author, opinion 

 wavering back and forth as to its validity for many years. The first 

 specimens received from this region by Mr. Bangs were inadvertently 

 described under a new name, Merula incompfa, but Mr. Hellmayr soon 

 corrected this mistake, and Dr. Allen had in the meantime indicated 

 the application of Bonaparte's name luridus to the present bird. Un- 

 fortunately, however, as recently shown by Dr. Oberholser {Proceed- 

 ings Biological Society of Washington, XXXIV, 1921, 106), this 

 specific term is antedated when used with Turdus. It differs from 

 T. grayi casius of Central America chiefly in slightly smaller size and 

 paler coloration of the under parts. Several birds in juvenal dress, 

 taken between August 17 and October 18, resemble the adults, but are 

 rather more tawny buff below, with obscure spotting; above with nar- 

 row tawny shaft-streaks, and the tips of the wing-coverts with large 

 triangular spots of the same color. 



A Tropical Zone species, found only on the coastal plain and up to 

 the lower foothills, scarcely going over 1,000 feet, and seemingly con- 

 fined to the low country on the western and the southeastern sides of 

 the Sierra Nevada, never having been observed on the coast between 

 Santa Marta and Dibulla. Simons did not meet with it in the Rio 

 Rancheria-Rio Cesar Valley, but it has recently been found here by the 

 writer, at Fonseca and Valencia. Judging from this, its range would 

 appear to be limited to the lower Magdalena basin, extending eastward 

 as far as the Santa Marta region along the foothills of the Sierra 

 Nevada. It was fairly common, according to the writer's experience, 

 around Fundacion, but could not be considered abundant in the vicin- 

 ity of Santa Marta. It frequents groves of scattered trees, open 

 woodland, and the edges of the forest. Its song resembles that of the 

 Robin, but unlike that bird it is very seldom seen on the ground. Mr.
