the aboye I have skins; but of skeletons I have quite a num¬ 
ber, and some useful ones among them. Besides birds we 
have lately got together a large collection of dried plants; so 
that we have been very busy; nor have we much chance of 
being otherwise.”* 
Mr. Jelski’s Collections in Western Peru. 
Mr. Constantin Jelski, a correspondent of the Warsaw Mu¬ 
seum, has lately made some remarkable discoveries in Western 
Peru, in the district round Tarma, east of Lima. Some of 
his novelties have been submitted to Dr. Cabanis, and are de¬ 
scribed in the f Journ. f. Orn/ (1873, pts. 1 & 3); amongst 
them is a very singular new form of Coerebkke (. Xenodacnis 
parina). M. Taczanowski has lately brought to London a 
number of specimens of M. JelskPs, which we have had the 
pleasure of examining. Amongst them are four or five 
Humming-birds new to science, and a single skin of a most 
interesting new Cotingine form quite distinct from any thing 
previously known. It is remarkable that a district already 
worked by Tschudi and other collectors should yield such 
results. P. L. Sclater. 
The Yellow-legged Herring-Gull. 
In the last number of the f Birds of Europe 3 Mr. Dresser 
figures the Yellow-legged Herring-Gull of the Mediterranean 
and Western Asia ( Larus leucophceus) . But this bird does 
not, as Mr. E. C. Taylor supposes, give place to Larusfuscus 
at Gibraltar. Larus leucophceus is certainly also found outside 
the Straits, as in 1867 the Zoological Society received a spe¬ 
cimen from Mogador*. This was determined by the writer as 
Larus fuseescens, being believed to be the Clupeilarus fusces- 
cens of Bp. (Consp. ii. p. 220). Since then two other living 
specimens have been presented to the Society by Mr. E. Bond. 
All three are now alive in the Regent's Park.
