the above 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 ' Journ. f. Orn.' (1873, pts. 1 & 3) ; amongst 

 them is a very singular new form of Coerebidse {Xenodacnis 

 parina). M. Taczanowski has lately brought to London a 

 number of specimens of M. Jelski's, 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 ' Birds of Europe ' Mr. Dresser 

 figures the Yellow-legged Herring-Gull of the Mediterranean 

 and Western Asia {Larus leucophaus) . But this bird does 

 not, as Mr. E. C. Taylor supposes, give place to Larus fuscus 

 at Gibraltar. Larus leucojihceus 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 fuscescens, 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. F. Bond. 

 All three are now alive in the Regent's Park.
