" Iris dark brown, feet and bill black." 



Perfectly identical with topotypical specimens from Paramba, 

 N.W. Ecuador, the head all round and the hind-neck being sooty 

 black, abruptly contrasting with the dark rufous brown of the 

 back. 



F. a. destructus is most nearly allied to F. a. nigricapillus Ridgw. 

 of Eastern Costa Rica. Dr. Hartert * having clearly pointed out 

 the difierences between the two races, I need not dwell any more 

 upon the subject. 



This Formicarms is confined to the lowlands and foot-hills of 

 the Pacific coast of Colombia and Ecuador. On the other side of 

 the Western Cordillera, in the Cauca Yalley, another species 

 or subspecies, F. saiuratibs Ridgw, t, takes its place. I have 

 examined the example from Remedios {Salmon) in the British 

 Museum, and an adult male obtained by the late J. H. Batty 

 at Los Jambos (Cauca Yalley) in Mr. Rothschild's Museum at 

 Tring, which I cannot distinguish from typical Trinidad specimens. 

 F. saiurattts is much paler grey underneath, has the sides of the 

 neck distinctly cinnamomeous, and the top of the head light 

 olivaceous brown like the back, besides some minor difierences.

These specimens agree well with others from Chiriqui (A. Lara 

 coll.). The female difi'ers from the male, in addition to its 

 smaller size, by having the breast somewhat clearer rufous, and
