Thryothorus lencotis (not of Lafresnaye) Lawrence, Ann. Lye. N. Y., \\], U'62, 

 320 (Panama R. R.). 



«Mr. Bangs mentions the "rather smaller" size as one of the characters of this 

 form; but I find that, taking the average of nine adult males of each, only the length 

 of the tail and middle toe is les.s than in T. m. modestus, all other measurements, 

 except that of tarsus, being greater.
