larger than the females. None of our Nicaraguan, Costa Rican, or Chiriqui specimens 

 quite correspond with the type of B. ruficeps, so that for the present we keep this bird 

 distinct. At the same time we have doubts as to its status, and believe that it will 

 some day have to be merged with B. homochroa. 



The single specimen brought from Panama by the late Mr. Hoggetts-Chambers, and 

 formerly in Mr. Sclater's collection, is the only one we have seen.

This species was at first referred by Mr. Lawrence to B. fumigata, Licht.^, but 

 subsequently described as distinct under the name of B. olivacea^. It was then 

 considered by Sclater and Salvin to belong to the Bolivian bird described by d'Orbigny 

 and Lafresnaye as Bendrocolaptes atrirostris^ — an opinion upset by Mr. Eidgway^, 

 who, on examining the supposed types of that species, pronounced the Panama bird to 

 be different, and reinstated Mr. Lawrence's name. This decision we now follow. 



B. olivacea is limited in its northern range to Honduras ; thence it passes along the 

 Isthmus to Panama, and into the north-western portion of the southern continent. 

 Being found on the line of the Panama Eailway it is doubtless a bird of the hot 

 tropical forests, and probably does not ascend the mountains to any considerable 

 elevation. M'Leannan obtained the types transmitted to Mr. Lawrence, and many 

 specimens were sent by him to us.

In many respects the single member of this genus resembles Bendrornis and its 

 allies ; the general coloration is similar, and the structure of the tail and feet with 

 their short hallux, the same. The bill, however, is very differently constructed ; it is
