The occurrence of the Harlequin Duck (Cosmonetta his- 

 trionica) in Italy is now registered for the first time. Two 

 young examples of this high northern form were obtained 

 in the estuary of the Po on the 2nd of March, 1902. 



3. ' The Auk. 3 



[The Auk. A Quarterly Journal of Ornithology. Yol. xix. Nos. 3 & 4, 

 July and October 1902.] 



In the July number Mr. H. W. Henshaw gives a very 

 interesting account of the species of the genus Chasiempis 

 found on the Hawaiian Islands and their distribution over 

 that group. Mr. John Grant Wells follows with an article 

 on the Water-birds of the island of Carriacou, a dependency 

 of Grenada, and situated about twenty miles to the north- 

 ward of it. Its Land-birds are enumerated in the October 

 part. Owing to the absence of forest, several woodland 

 species found in St. Vincent and Granada are not repre- 

 sented in Carriacou, but its extensive swamps are highly 

 attractive to aquatic and wading birds, and the notes on the 

 species which breed there are of considerable interest. Mr. W. 

 Hubbell Fisher, having had his attention called, by a passage 

 in Mr. F. M. Headley's ' Structure and Life of Birds' (1895), 

 to the vise of the bastard wing for checking flight iu the 

 domestic Pigeon, has found, from study and photographs 

 taken at Munich, that this natural " break " is also put 

 " hard down " by the Stork when preparing to alight. Dr. 

 Jonathan D wight's paper on Plumage-cycles and the relation 

 between Plumages and Moults requires close study, and an 

 abstract would hardly do it justice, but his table illus- 

 trative of the sequence of these changes has a plausible 

 appearance and may stand the test of extended use. British 

 ornithologists will take especial interest in Mr. O. P. Hay's 

 account of the finding of some bones of the Great Auk in a
