The rule "once a synomym, always a synonym" necessitates 

 the rejection of the specific name ' pinus' for the Pine Warbler, 

 as will be seen from the following account. 



Linnaeus (S. N. 12 ed. I, p. 187), in 1766, described correctly 

 the Blue-winged Yellow Warbler as Certhia pinus basing it 

 upon Edwards's plate 277, upper figure. Mislead by the latter 

 author he quotes as a synonym Catesby's plate 61, which is a 

 poor representation of the Pine Warbler. Latham, in 1790, re- 

 ferred the bird described by Linnaeus to the genus Sylvia calling 

 it Sylvia pinus, a name which was adopted by Vieillot, 1807, in 

 his Birds of North America. 



Wilson, in 1811 (Am. Orn. Ill (p. 25)), demonstrated that 

 the birds figured by Edwards and by Catesby are different spe- 

 cies. Well aware of the term Sylvia pinus, he did not intend it 

 as a new name, but he simply restricted it to Catesby's bird. In 

 this he was wrong, as we have seen above. He should have left 

 the name Sylvia pinus with the Blue-winged Yellow Warbler 

 and given a new name to the Pine Creeper, but, instead, he be- 

 stowed the new name upon the former, calling it Sylvia soli- 

 taria. It should also be noted that the two birds were both in- 

 cluded by him and subsequent writers in the genus Sylvia. 



It is evident that Sylvia pinus Wilson 181 1, nee Latham i79°i 

 cannot stand under any circumstance. Another name being nec- 

 essary we will have to take the one bestowed by Audubon, in 

 1832, viz.. Sylvia vigorsii. The species should in the future 

 be known as 



Dendroica vigorsii (Aud.).

DESCRIPTION OF A NEW CARDINAL GROSBEAK 

 FROM ARIZONA. 



BY ROBERT RIDGWAY. 



The Cardinal Grosbeak from Arizona, hitherto supposed to 

 be identical with C. igneus from Cape St. Lucas, proves, on 

 comparison of numerous specimens, to be easily distinguishable.
