really distinct. The female is not distinguishable from schistaceus. See also 
Nov. Zool. xiv. 1907. pp. 61-3, where a review of these birds is given, 
A nest containing two eggs was taken at 8. Isabel, together with the parent 
bird (No. 633), on October 7, 1907. It is a small, loose structure of dry leaves, 
roots, and stems of various plants, withont a particularly soft lining, fastened on 
a forked branch like an oriole’s nest (Oriolus galbula). The eggs, which resemble 
those of the Red-backed Shrike (Lanius collurio), are creamy white, mottled and 
blotched with chocolate and underlying pale lavender, the chocolate markings being 
crowded around the thicker end. The eggs measure 21 x 15, 20 x 154 mm.

“Tris brown or grey, feet plambeous (black), bill black.” 
The males have the throat and middle of the foreneck deep black. The outer 
rectrices are conspicuously edged with white at the tip. Some have scarcely more 
white at the base of the interscapular feathers than examples from British Guiana, 
Venezuela, etc., but average slightly larger with longer tail. Cf. my remarks in Nov. 
Zool. xiv. p. 371, and in Verhandl. Zool. Bot. Gesellsch. Wien liii, 1903. pp. 216-7.
