This I have not aeeu a.s published in the Bulletin. It was immediately reproduced, com- 

 bined with the author's paper of 1877 on the same subject. See next title. 



Thi.s paper continues tlie author's important researches into the moult of the bill in cer- 

 tain Alcidm, and show.s tliat, as was expected, the same conditions obtain among the various 

 Pacific forms related to Fratercula arctica. The happy discovery, so imi)ortant in itself, was 

 further tlie means of settling the status of several vexed species. The following are the main 

 points of this admirable study : 



A fiimily, JUormonidce, is separated from Alcidce to accommodate the genera Fratercula, 

 Lunda, Ceratorhyncha , Ombria, and Siinorhynchus, in which there is a moult of iiortious of 

 the bill, and a double moult of the plumage. The whole matter of the seasonal changes, 

 both of the bill and of the plumage, is very elaborately presented. 



Fratercula arctica is ditferentiated into three geographical races, shown by a colored map 

 to corre-spond with certain isothermal lines. F. armoricana (n. v.), of certain portions of 

 Europe alone, chiefly south of 60° N. lat. ; F. islandica (n. v.), of general dispersion on the 

 north coast of Europe, in Iceland, Southern Greenland, Labrador, Newfoundland, and Ko- 

 diak Island in the Pacitic: F. glacialis, of Sjiitzbergen, Northern thieuland, and possible 

 Northern Labrador. 



The moult of the bill in Fratercula corniculata is the same as in F. arctica, excepting that 

 one pair of the deciduous pieces is wanting. The moult of the eyelids is the same. 



The moult in Lunda cirrhata is tlie same as in F. corniculata, as far as the bill is concerned ; 

 but there are no excrescences to shod from the eyelids. The Sagmatorhina lathami of Bona- 

 parte is the young bird. 



Ghimerina cornuta (Ceratorhina laonocerata) moults the horn and a small horny strip 

 below the nostrils. The C'erorhina suckleyi or Sagmatorhina suckleyi is the same bird, 

 young or old, without the lioni. 



Ombria psittacula sheds a saddle-shaped piece from the base of the ui>per mandible. 



Simorhynchus cristatellus sheds all the red parts of the bill, in four pairs of pieces, three 

 from the upper mandible. S. " dubius" and S. " tetraculus" are the same bird, without these 

 ornaments. 



Si'morhynchus eamtschaticiis probably moults one pair of pieces from the upper mandible, 

 being nearest in respect to Ombria. S. cassini of Cones is the young biid. 



Simorhynchus m.icrocero8 moults the tubercle on the ujjper maiulible. .S'. pusillus is tlie 

 same bird. 



The author does not appear to have seen Brandt's latest paper, in which he makes a similar 

 reduction of the species of this group. It may be added, without detracting in the least from 

 the merit of M. Bureau's brilliant discovery, that his determinations of species are, wilhout 

 exception, the same as those given in E. Cones "Key to North American Birds,'' 1872. 

 Neither Brandt nor Coues had any idea of the actual state of the case, so far as the moult of 

 the bill is concerned, but made their determinations of species upon other considerations.
