entered into upon the variations, and a series of measurements 
is given, and we have no complaint to make. 
Pica cyanea , Pallas (p. 318), of Siberia, is very unnecessarily 
united with the Spanish bird, Pica cooki , Bp. It may be very 
true that in the Siberian bird the amount of white at the 
termination of the two medial rectrices varies a little; but had 
Spanish examples been examined, it would have been seen at once 
that the white spot is here not present at all! 
Corvus monedula ! (p. 324). Even Professor Schlegel, who 
cannot be pronounced a species-maker, allows Corvus dauricus 
to be a distinct species from the European Jackdaw. Dr. v. 
Schrenck does not even consider it as a permanent local variety. 
It is very true that intermediate forms are found. In S.E. 
Europe we have Corvus collaris of Drummond, which may be 
so termed. But there are several, not to say many, well- 
known cases of intermediate forms between representative 
species. 
Cinclus pallasii (p. 331) is united with Cinclus mexicanus — 
a union, which such examples of these birds as have fallen under 
our inspection would certainly not justify. 
Oriolus cochinsinensis, var. indica ! (p. 346). The Black- 
naped Orioles are certainly separable into several well-marked 
local forms, which ought not to be confounded, whether they are 
called species or varieties. The true Philippine bird ( Oriolus 
acrorhynchus of Vigors) is much larger than 0. sinensis , to which 
race we suppose the Amoor specimens belong, and has no trace 
of the yellow speculum. If Dr. v. Schrenck had a series of 
examples from all the different localities before him, we have 
little doubt he would be able to distinguish them easily. 
Lusciola ( Nemura) cyanura , Pallas (p.361), is, we are informed, 
“ without doubt” the same bird as that which Hodgson has 
described as Nemura rujilata from Nepal. That these two 
species are congeneric we well believe; but that they are strictly 
identical could not be safely predicated without an accurate com¬ 
parison of specimens. Dr. v. Schrenck has not had the oppor¬ 
tunity of doing this, perhaps; but even an examination of the 
figure of Nemura rufilata in the < Contributions to Ornitho¬ 
logy 5 might have induced him to modify his assertion. The
