606 MR. P, L. SCLATER ON THE [June 27, 
Herr v. Pelzeln adds—‘“ The two nests brought back by Natterer 
are of the following dimensions: breadth rather more than 2", dia- 
meter of entrance-hole about 1!. The feathers used in construction 
are greyish brown with white shafts, with some green feathers mixed 
in. The cement is doubtless the saliva of the bird, as is the case 
with other Cypselide.”’ 
Mr. Wolf’s plate (Pl. XX XIII.) includes a figure of the nest from 
a drawing kindly sent me by Herr von Pelzeln.

I have never seen examples of this species. The figure represents 
the tarsi naked and the hallux placed posteriorly, so that it may 
belong to the next subfamily. But very little dependence can be 
placed on D’Orbigny’s figures; and Bonaparte says (Consp. p. 66) 
“ minime ACANTHYLIS.”
