1845. Strickland, H. E. On Cyanocitta, a proposed new genus of Garrulinse, and 

 on C. superciliosa, a new species of Blue Jay, hitherto confounded with C. 

 ultraniarina, Bonap. <^ Ann. May. Nat. Hist., xv, 1845, pp. 260, 2G1. 



The type of Ihc new genus Cyanocitta is expressly stated to- be Garrulus cristatus (Linn.); 

 wrongly given by most American writers as Q. superciliosa:^ G. calif or nicus.^G. cristatus is 

 wrongly given by G. R. Gray and others as the typo of Swainson's genus Cyanurus, 1831, upon 

 the assumption that the first siiecies mentioned by an author under a genus must be consid- 

 ered his type of that genus. But Swainson himself says that cristatus, etc., are aberrant 

 members of his genus Cyanurus. Therefore, Cyanurus Sw., 1831, is a sj-nonym of Cyanoco- 

 rax Boie, 1826, leaving Cyanocitta Strickl., 1845, to stand for the crested blue jays of America 

 typified by C. cristatus, stelleri, etc. — See P. Z. S., 1876, p. 268, note.

This paper requires close attention to catch its drifti. The authors " Napoh-onic " tendency 

 to transfer, substitute, and otherwise interfere with the genera of other authois, to suit his 

 own notions, is here seen at about its worst : and this abuse of generic nonicuclatme in Gar- 

 ruling has jjrovoked endless confusion. 



Gray's Lophocitta, 1840, vice Platylophus Sw., is applied (p. 79) to Gurndus histrionicus 

 Miill., and Corvus galericulatiis Cuv. 



Garrulus liOthi, p. 80, ])!. IT, is a new species ; other species of Garrulus treated are G. 

 lanceolatns Vig., glandarius T.. japonicus Schl., kryniehii Kalcn., melanoecphalus Bonelli, 

 brandti Eversni., and bispecularis Vig. 



CyanogarruliisTip., p. 83, is 'dismembered" from Cyanocorax Boie, 1826. for C. cristatus, 

 etc., becoming thus exactly synonymous with Cyanocitta Strickl., 1845.
