Bangs — Neio or Rare Birds from. Western Colombia. 73 



duller, more olivaceous, less reddish brown; throat and sides of neck 

 ochraceous instead of orange-rufous ; body below from the chest back- 

 \\ar(l uniform tawny ochraceous, wholly unstreaked, darker and Ijrowner 

 on flanks and under tail coverts; pileum and cervix with narrow, pale 

 shaft streaks to all the feathers — very different from the solidly Ijrown 

 pileum of R. rufibrunneus. 



Measurements. — Type, adult c?, wing, 97.5; tail, 91; tarsus, 27; cul- 

 men, 25.5. 



But one specimen, the type, of this very distinct species was contained 

 in the collection sent me. It represents a species wholly unlike Autoinolus 

 ignohilis Scl. & Salv. or any other species so far as I can find, except R. 

 rufibrunneus, from which also it is strikingly different. 



Myrmeciza berlepschi Ridg. 



This species was represented by six specimens, adults of both sexes, 

 from Palmar, Pavas, and La Maria, western Colombia, taken in Febru- 

 ary, March, and June, which I have compared with the type from Chimbo, 

 Ecuador, and find to be identical with it. 



Rhynchocyclus sulphurescens asemus subsp. nov. 



Type from near Pavas, western Colombia, 4,400 feet altitude. Adult 

 6^, No. 23,439, Bangs collection. Museum of Comparative Zoology. Col- 

 lected February 15, 1908, by M. G. Palmer. 



Characters. — Almost exactly intermediate between Rhynchocyclus cin- 

 ereiceps of Central America and R. sulphurescens ccorticns of the Santa 

 Marta region of Colombia; differing from the former in having the throat 

 and chest less strongly gray, but with the cap and back identically the 

 same ; from tlie latter it ditfers in having the cap much darker and clearer 

 gray — less mixed with olive green ; the back darker olive green ; and the 

 throat and chest just a trifle grayer. 



Measurements. — Type, adult c?, wing, 70; tail, 59; tarsus, 18; cul- 

 men, 11.5. 



Three skins of this form were sent in— the type, and two adult males 

 from Jimenez, killed in May. Tlie subspecies is one of those that has no 

 one very good character to distinguish it, but that is exactly intermediate 

 between two quite different birds, resembling above R. cinereiceps and 

 below R. evorthms. 



It proves conclusively to my mind that R. cinereiceps is nothing more 

 than a northern subspecies of R. sulphurescens. 



Mionectes olivaceus hederaceus subsp. nov. 



Type from near Pavas, western Colombia, 4,400 feet altitude. Adult 

 9 , No. 23,442, Bangs collection. Museum of Comparative Zo(jlogy. Col- 

 lected February 12, 1908, by M. G. Palmer. 



Characters. — Like M. olivaceus venezuelensis Ridg. in having under 

 parts heavily streaked, but much darker, more grayish olive below; 

 duller and darker greenish olive above, with the pileum nuich darker and
