larger than the females. None of our Nicaraguan, Costa Rican, or Chiriqui specimens 
quite correspond with the type of D. rujficeps, 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 D. 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 D. fumigata, Licht.1, but 
subsequently described as distinct under the name of D. olivacea?. It was then 
considered by Sclater and Salvin to belong to the Bolivian bird described by d’Orbigny 
and Lafresnaye as Dendrocolaptes atrirostris®°—an opinion upset by Mr. Ridgway ’, 
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. 
D. 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 Railway 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 Dendrornis 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
