388 Fourteenth Supplement to the A. 0. U. Check-List. [f^^ 



Genus CYANECULA Brehm.' An earlier name occurs in 



Genus CYANOSYLVIA Brehm. 



Cyanosijlvia Brehm, Isis, XXI, 1828, 920. Type, Motacilla 

 suecica Linn.eus. (C/- Ridgway, Bull. U. S. Nat. Mus., 

 No. 50, Ft. IV, 1907, 14.) 



764. Cyanecula suecica (Linn.eus). This is changed to 

 764. Cyanosylvia suecica robusta (Buturlin). 

 Siberian Red-spotted Bluethroat. 



Cyanecula suecica robusta Buturlin, Orn. Monatsb., XV, 

 1907, 79. (C/. Buturlin, Auk, XXV, 1908, 35; Ridgway, 

 /. c, 226.) 



766a. Sialia sialis azurea (Baird). This becomes 

 766a. Sialia sialis fulva Brewster. 



Sialia sialis fulva Brewster, Auk, II, 1885, 85. 



Sialia azurea Swainson, 1827, was not a nomen nudum, as 

 usually supposed, but a substitute name for Sialia sialis; it is 

 therefore not available for the Azure Bluebird, the earliest name 

 for which appears to be fulva, as above. (Richmond, MS.) 



768. Sialia arctica (Swainson). A much earlier name occurs in 



768. Sialia currucoides (Bechstein). 



Motacilla s. Sylvia currucoides Bechstein, in Lathaini, Allg. 

 Ueb. Vogeb'lII, ii, 1798, 546, pi. 121. 



Swainson described and figured the Arctic Bluebird in 1831, 

 and his name, '' Erythaca {Sialia) arc/ica" is. generally supposed 

 to have been the earliest reference to the species. It is now found, 

 however, that Bechstein gave a description and colored figure of 

 this species in 1798, under the name Motacilla s. Sylvia currucoides, 

 which name is accordingly adopted. (Richmond, MS.)
