APPENDIX IV. 
Additional Remarks on these Birds, communicated to me hy the 
Nohleman in whose Collection theij are now deposited. 
No. 1. Lanius poliocephaluSy or Ash-crowned Shrike. 
Length inches. Bill above i of an inch, blackish, and much covered with 
the feathers of the front ; crown of the head hoary livid colour, lightest 
about the eyes ; a blackish spot on the ears; a collar of white surrounds 
the neck, and covers all the under parts of the body, as also the under tail 
coverts, which becomes a dirty white on the belly ; the general colour of 
the back and wings is a brownish black, but a line of white extends along 
the latter, from the point of the shoulder across the coverts and down the 
exterior web, almost to the shaft of the two tertial quills nearest to the 
body ; the remainder are tipped with white, and the rest of the quill 
feathers have each a large round spot on the inner web, which stretches in 
an oblique line across the wing, from the tip of the tertials to nearly the 
root of the first quill feather; but this line is not visible unless the wing be 
extended. The tail is square at the end, the two outermost feathers on 
each side are wholly white, the third is deeply edged, and tipped with 
the same, but the remaining feathers are only tipped with it, so as to give 
the effect of a cuneiform tail of black laid upon a square one of white. Legs 
lightish ochre ; claws brown. The feathers of the head appear a little 
inclined to a crest ; but from the manner in which the skin had been pressed 
flat for preservation, it may be doubtful whether they were so in reality. The 
two specimens seen were precisely similar. Dr. Latham appears to have 
considered this as very nearly allied to, if distinct from, the Pic Griesche 
silencieux of Le Vaillant, Ois. pi. 74. f. 1. and 2. ; but on a strict compari- 
son of the bird, now that it is set up, with that plate and description, I 
consider this as a distinct species, and have therefore ventured to give it a 
name. The bill is straightish, with a little curving in at the end, and a 
very small notch.
