Til the first section of tins ;j;roti|> wc see the siinie iiidicution of variation 

 fiDiii a c'oinnioii type with the rej^noii that is so evident in Cifdntnut. 'J'hus, 

 Cjimiovitta woodhvKsei ditfers from caUfirnilva, niiich as Cjiiunira nudro- 

 lopha does from C. stclleri (\iiT. frontal is), in more slender l»ill and a greater 

 ]iercentage of hlue ; this invading the hack and nnder i)arts, the lower tail- 

 coverts especially. Ihit here the ])arallel of motliticjition ends, for the 

 iVlexican rei)resentative of the species (6*. sninichi'usti) appears to rcert 

 back to the characters of califoniica, having like it a iiiininiiiin aiiKumt of 

 blue, thougli this almost obliterates the siijierciliary stri])e of white. In 

 this respect there is more resemblance to the case of Pipilo fasm and its 

 three races in the three regions inhabited by these representative forms of 

 Cyanocitta calif arnica ; for, while the Mexican {P.faaca) and Californian (/*. 

 crissalis) are very much alike, the one from the intervening region {P. mcso- 

 leiica) is more different from the two extreme races than they are from each 

 other. 



In the other section of the genus the relation between arizona' and 

 sordida is a ])arallel to that between Ciianura macrvlopha and C. coronata ; 

 the southern forms {sordida and coronata) differing puincipally in the greater 

 intensity and prevalence or amount of the blue. The rela'ions of rourhi 

 and ultramarina to the two above mentioned are yet oltscure, owing to the 

 small material at command, — there being only two specimens of the former, 

 and none of the latter, in the National Museum at Washington.
