AIO General Notes. Aue 
sub-specific name, when it radically disagrees with or is contradictory to 
the characters given in the diagnosis or description based upon it.” This 
ruling, if strictly enforced, precludes the use of the name lewcogaster for 
Baird’s Wren. Under such circumstances, following the directions given 
in the Code, the bird must be ‘reintroduced into science under a new 
name, as a new species, and with a proper description.” Mr. Ridgway 
(Auk, IV, 1887, 349) long ago maintained that Dr. Hartlaub described 
Baird’s Wren, as Tkhryothorus murinus, in 1852 (Rev. et Mag. de 
Zool., 2d Sér., IV, 4),— twelve years before Baird called it ZThryothorus 
bewickit leucogaster (Gld.), and twenty-eight years before Messrs. Salvin 
and Godman again introduced it as TAryothorus bazrdz. 
Baird’s Wren has figured in both the first and second editions of the 
A. O. U. Check-List as Thryothorus bewickit batrdi (Salv. & Godm.). In 
the Eighth Supplement to the Check-List (Auk, XIV, 1897, 131), this 
name is changed to 7. 6. leucogaster Baird (zec Gould!) in compliance 
with the views of Dr. Coues (Auk, XIII, 1896, 345). It seems to me that 
Mr. Ridgway, although starting with the false premise that Tvoglodytes 
leucogaster Gld. equals Cyphorhinus pustllus Scl., arrived at the correct 
name for Baird’s Wren when he called it Zhryothorus bewickit murinus 
(Hartl.). If Mr. Ridgway’s determination of murzuus be questioned, it 
should be tested by an appeal to Dr. Hartlaub’s types in the Museums of 
Bremen and Hamburg; if it prove erroneous, then the name Jbazrdi 
Salv. & Godm. becomes available as the subspecific name for Baird’s 
Wren. After what has been shown above concerning Baird’s acquaint- 
ance with the type of Tvroglodytes leucogaster Gld., it seems no longer 
justifiable to identify it with Cyphorhinus pustllus Scl., which should 
now be known as Hemzura pusilla (Scl.), not H. leucogastra (Gld.).—

Rare Birds in the Vicinity of Philadelphia.'"— On Sept. 5, 1894, a spec- 
imen of Contopus borealis was secured near Holmesburg, Pa., and on May 
18, 1895, a specimen of Empitdonax traillit alnorum was secured. 
This is, I believe, the first definite record for the latter in this part of 
the State, as lam unable to findany in Stone’s ‘Birds of Eastern Pennsyl- 
vania and New Jersey.’ 
While collecting in Tinicum Township, Delaware Co., Pa., May 15, 
1897, I secured a male Prranga rubra. ‘This is the third record during 
the last twenty years for this species in this part of the State. —H. W.

Notes on Some Ontario Birds. — Occasionally Brtinnich’s Murre ( Wra

winter; in fact this bird is not an infrequent visitor at Kingston in the
