GENUS CYANECULA Breum. An earlier name occurs in 
GENUS CYANOSYLVIA Brenum. 
Cyanosylvia Breum, Isis, XXI, 1828, 920. Type, Motacilla 
suecica LinNz=vS. (C]. Ripaway, Bull. U. S. Nat. Mus., 
No. 50, Pt. IV, 1907, 14.) 
764.  Cyanecula suécica (Linnzus). ‘This is changed to 
764. Cyanosylvia suecica robusta (BUTURLIN). 
Siberian Red-spotted Bluethroat. 
Cyanecula suecica robusta Bururtiy, Orn. Monatsb., XV, 
1907, 79. (Cf. Bururuin, Auk, XXV, 1908, 35; Ripeway, 
t. ¢., 226.) 
766a. Sialia sialis azurea (Barrp). ‘This becomes 
766a. Sialia sialis fulva BREWSTER. 
Sialia sialis Julva Brewster, Auk, II, 1885, 85. 
Sialia azurea SWAINSON, 1827, was not a nomen nudum, as 
usually supposed, but a substitute name for Sralia sialis; it is 
therefore not available for the Azure Bluebird, the earliest name 
for which appears to be julva, as above. (RicumMonp, MS.) 
768.  Sialia arctica (SwarNson). A much earlier name occurs in 
768.  Sialia currucoides (BECHSTEIN). 
Motacilla s. Sylvia currucoides BECHSTEIN, in LATHAM, Allg. 
Ueb. Vogel, III, ii, 1798, 546, pl. 121. . 
Swainson described and figured the Arctic Bluebird in 1831, 
and his name, “‘Erythaca (Sialia) arctica” 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. (RicuMonp, MS.)
