It agrees perfectly with a female collected by Natterev near Para. Having 

 always suspected that the bird described by Mr. Ridgway miicht be the same 

 as the preseut species, I asked the latter geutlemau to compare his type with the 

 specimen of D. spixi in the American Museum of Natural History. Mr. Itidgway 

 kindly writes as follows : " I have now before me the American Museum sjjecimen 

 of D. sjAxi, from Pard. On comparing it with the type of my D. fraterculus, I 

 note that they are very much alike, and probahly the same form ; but the type of 

 D.f rate rod tits is badly made nj), the head and neck being shoved back against the 

 shoulders, and this causes some differences which are doubtless more apparent thnii 

 real : for example, the back appears uniform olive-brown, except the extreme upper 

 portion, and the pale spots on the <'hest appear (thronj^h crowding) to be shorter. 

 Actual ditl'erences consist in the decidedly darker and more olive hue of the brown 

 on both upper and under parts, and the darker (nearly black) ground colour of 

 the pileum. These differences, however, are well within the range of individual 

 variation in allied sjiecies, and I have little doubt the bird is really 1). spixi." 



]>. spill is a very distinct species, perhajjs nearest related to U. elegans Pelz. 

 and D. trisignis Hellm., with which it agrees in shape and size of the liill. In 

 colour it reminds one rather of 1). si/surrans, but the pale markings on the breast 

 and belly are much more longitudinal, and the latter bird has a much larger and 

 quite differently shaped bill. 



It is astonishing that Mr. Elliot, in his monograph of the genus JJendrornis, 

 declares D. fraterculus to be inseparable from T). susurrans — wholly neglecting their 

 widely separated areas of distribution — and at the same time allows I>. npij-i to stand 

 as a distinct species on the strength of the same specimen which Mr. Ridgway, as 

 quoted above, states to be identical with the type oi l>. fraterculus !

The latter, though marked as a male, is probably a female, and differs from 

 the larger one in having the pale shafr-stripes on the upper back more bnffy, not 

 so whitish. Both specimens have the bill entirely black, and the middle of the 

 abdomen is slightly suffused with fulvous.
