obtaining thoroughly identified eggs and young in down 

 is indefinitely postponed ; for although two fine adults (one of 

 them now in Mr. Seebohm's possession) appear to have been 

 obtained last summer near Disco, in Greenland, further 

 information is wanted as to the egg said to have been taken 

 with them. At p. 200 of this interesting report, of which 

 we have only given a brief abstract, is a list of a few birds 

 observed at Plover Bay, Eastern Siberia.

In the former of these two articles the group of the Great 

 Northern Falcons is discussed by the late Professor whose 

 name we retain in the orthography familiar to our readers. 

 The single specimen from Bering* Island, on which is based 

 the Hierofaico grebnitzkii, sp. n,, to judge by the pretty figure 

 and description, does not seem to depart very materially 

 from the form which is usually known to Eurojiean orni- 

 thologists as Falco islandu^ ; and so thinks Dr. Stejneger 

 who himself obtained four examples of the Bering Island 

 Grey Falcon, besides a fifth received from Mr. Grebnitzky, 

 though, in accordance with the view before announced (Auk 

 1885, p. 187), Dr. Stejneger names it F. rusticolus, con- 

 sidering F. islandus to be that which in this quarter of the 

 globe has usually been called F. cand'icans or groenkmdicus. 

 The second supposed new species, Hierofaico uralensis, has 

 already been noticed in these pages (Ibis, 1883, p. 105). 

 We should doubt its being more than a local form of F. gyr-

 " Behring " anctorvm lylurimonwi, and those who choose to fo:iow a 

 multitude to do evil will continue to misspell it.
