Great differences of opinion appear to exist as to the number 
of species into which the Grey Shrikes ought to be divided. 
Dresser and Sharpe, in their “ Notes on Lanius excubitor 
and its Allies” (P.Z.S. 1870, p. 590), recognized two Si- 
berian species. Two skins from the Amoor, fortunately still 
in the Swinhoe collection, were identified by these ornitho- 
logists as adult and immature of Lanius lahtora (Sykes). 
The adult bird is stated to be ‘ absolutely similar in every 
respect”’ (the italics are not mine) to examples of old L. 
lahtora from the Punjab. The second Siberian species was 
identified doubtfully, from Pallas’s description of L. major, 
with the American L. borealis, Vieill. I think Dresser and 
Sharpe were wrong in both their facts, but right in at least 
one of their conclusions. The adult bird of the first species, 
so far from being absolutely similar in every respect to L. 
lahtora, differs from that species in having the general colour 
of the upper parts considerably paler, and in wanting the 
narrow black frontal line at the base of the bill. The im- 
mature bird is what is generally recognized as L. major, Pall., 
which these writers professed never to have seen. 
In the ‘ Journal fur Ornithologie ’ (1873, p. 75) the sub- 
ject is handled by Cabanis with that minute attention to 
details so characteristic of the German mind, and two new 
species are described, L. homeyeri and L. sphenocercus. In 
addition L. major, Pall., is recognized as a Siberian bird. 
We may at once dismiss L. meridionalis, Temm., and L. 
algeriensis, Less., as western forms, which have nothing to 
do with Siberia. L. lahtora, Sykes, seems to me to have no 
better claim to be considered a Siberian bird. In the allied 
species black hairs, apparently an extension of the rictal 
bristles, are found on the forehead at the base of the bill; but 
in L. lahtora, Sykes, more or less black feathers are found there 
in addition, causing it.to approach in this respect L. excubito- 
roides, Swains., where these black feathers are still more
