This form of Dendrocinda, though occupying in part the same reg 

 as D. ruficeps, is apparently distmct, differing in its larger size ; much 

 more reddish rump, back, and lower parts; and more uniform' upper 

 surface, the pileum being in color less definitely distinct from the inter- 

 scapular region.
