The type of Ihe new genus Cyanocitta is expressly stated to be Qarrulus cristatus (Linn.); 

 wrongly given by most American writers as O. superciliosa=G. calif ornicus. — G. cristatus is 

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

 the assumption that the first species 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 synonym of Cyanoco- 

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

 typifi(?,d by C. cristatus, stelleri, etc.— See P. Z. S., 1876, p. 268, note.

This paper requires close attention to catch its drift. The author's " jSTapoleonic " tendency 

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

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

 rulinoe has provoked endless confusion. 

 » Gray's Lophocitta, 1840, vice Flatylophus Sw., is applied (p. 79) to Ourndus histrionicus 



Miill., and Corvus galericulatus Cuv. 



Garrulus lidihi, p. 80, j)l. 17, is a new species ; other species of Garrulus treated are G. 

 lanceolatus Vig., glandarius Y., japonicus Schl., krynickii Kalen., '>nelanocephalus Bonclli, 

 brandti Evorsni., and bispecularis Vig. 



Gyanogarrulusliyy., p. 83, is "dismembered" from Cyanocorax Boie, 1826, for G. cristatus, 

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