ICTERUS MESOMELAS SALVINII (Cassin). 

 SALVIN'S ORIOLE. 



Similar to I. m. mesomelas, but decidedlj^ larger, without trace of 

 white edging to secondaries, and with more black on tail (fourth rec- 

 trix wholly black, and much more than basal half of third rectrix 

 black). 



Adult male.—ljength (skins), 215.9-238.8 (228.9); wing, 87.6-101.6 

 (96.3); tail, 100.3-114.8 (107.7); culmen, from base, 24.4-26.9 (25.4); 

 depth of bill at base, 9.7-10.7 (10.2); tarsus, 30-32.8 (30.7); middle toe, 

 18.3-21.8 (20.3).' 



Adult female.— Length (skins), 199.7-223.5 (212.3); wing, 86.6-98.3 

 (92.7); tail, 98.6-108.5 (104.9); culmen, from base, 22.9-24.9 (23.6); 

 depth of bill at base, 10.2; tarsus, 29.7-30.5 (30); middle toe, 19.8- 

 20.3 (20.1).'' 



'Ten specimens. 

 ^ Five specimens. 



Specimens from Central Colombia ("Bogota") are still smaller than Panama ex- 

 amples, and occasionally have indistinct white edgings to the secondaries. They are 

 thus intermediate between I. m. salvinii and /. m. taczanowskii (Eidgway, Proc. Biol. 

 Soc. Wash., iii, Apr. 15, 1901, 153), of western Ecuador and Peru, though nearer the 

 former.
