156 THE AUSTRAL AVIAN RECORD [Vol. IV. 



I. and II., pp. 321-528. Ackn'd B.F. Jan. 6, 1821. 

 II., 529-848. July 6, 1822. 



III., 849-1460. July 26, 1823. 



Consequently Vieillot's name Larus leucopterus has priority 

 and it prohibits the usage of the later name by Faber. 

 VieiUot's name refers to the Glaucous GuU, not the Iceland 

 Gull. Somewhere about the same time Temminck noted the 

 distinctions, as did Edmondston in Britain. In the Mem. 

 Werner Nat. Hist. Soc, Vol. IV., pt. i., p. 185, May 1822, the 

 latter introduced Larus islandicus for a new Gull, which proved 

 to be the Glaucous Gull, but on p. 506 of the same volume, 

 published in 1823, he used it for the Iceland Gull and it was 

 so used for a little time by British ornithologists. In the Isis, 

 1822, heft v., col. 562, Boie included " glaucoides Temm. 

 leucopterus Faber," wliile Meyer in the Taschenb. deutsche 

 Vogel Zusatze, Vol. III., p. 197, also published in 1822 and the 

 preface dated April, included " Larus glaucoides Temm." and 

 gave a full description. Two or three names were later added, 

 but glaucoides Meyer ex Temm. MS." seems to be the best 

 claimant. 



It may be noted that there is a Larus glaucodes Meyen, 

 Nov. Act. Acad. Cses. Leop. Car., Vol. XVI., Suppl., p. 115, 

 1834, which is in use for another Gull. The difference between 

 glaucodes and glaucoides is slight, and whereas the first ma}^ 

 be from glaucus, the colour above, the latter appears to be 

 from glaucus, as referring to the Gull, a distinction too subtle 

 for general usage. 



An extraordinary result of the preceding inquiry is the 

 discovery of an error in the American Check List. That List, 

 through the co-operation of the best ornithologists, is a fine 

 production and little complaint can be made in any direction, 

 consequently the detection of a slip is a notable item. On 

 p. 40 of the third edition we find " Larus jranklini Richardson, 

 Fauna Bor. Am., II., p. 424, pi. 71, 1831 = 1832." 



This is continued in Ridgway's Birds N. & Mid-America, 

 p. 641, as Chroicocephalus franklinii (Swainson and Richardson) 

 1831," the same reference being given. As a synonym is 

 Larus pipixcan Wagier, Isis, heft 5, 1831, col. 515, Mexico."
