The Deltoid Muscl^fffee ^EwiSfe. — iin*e£aminm^Pn umber of Swifts 
recently I was struck with the fact that our common Chimney Swift 
( Chcetura pelagica ) lacks the deltoid muscle. This is interesting as being 
another instance of the specialization of the Swifts along various lines, 
and also as showing the structural variation among different members of 
the group. In Macropteryx the deltoid is well-developed and arises from 
two heads as in the Passeres. In Cypseloides, Micropus , Collocalia , and 
Tachornis , the deltoid is single and reduced in size, being proportionally 
smallest in Tachornis. Finally, as stated above, the deltoid is quite absent 
in Chcetura pelagica , this being a step beyond what is found among the 
Hummingbirds, where the deltoid is present though small. It would be 
interesting to know if other members of the genus Chcetura lack the 
deltoid, and also what is the condition of this muscle in Hemiprocne. 
Dr. Shufeldt’s figure of the wing muscles of Chcetura (Linn. Soc. 
Journ. Zool. XX, pi. 22, fig. 29) shows that he too found this muscle 
absent, although nothing is said about it in the text. 
I would be extremely grateful to any one for alcoholic specimens of 
Hemiprocne or any species of Chcetura save, pelagica. — F. A. Lucas, 
Washington , D. C. 
A C himney Swift impaled on the point 
of a lightning rod, caused, no doubt, “ by 
his headlong plunge down to his nest.”

C himney S wallow s. The janitor of the block in which 
my office is located, yesterday brought me a fine pair of 
Chimney Swallows, which he captured in the ‘‘dust box” in 
the basement of the building. The place where they were 
found is 160 feet from the top of the chimney— and the 
birds must have been there some time, as they were very 
weak and made no resistance when captured. They are 
very tame, and although I have placed them on the window 
sill several times, they have come back into the building, 
and seem perfectly satisfied to remain. — Fletcher M. Noe, In-

The common Chimney Swift is called Chcetura pelagica. The 
latter term implies a pelagic habitat, and is peculiarly appropriate 
when applied to the Stormy Petrel, or other Sea-birds. But who 
ever heard of the Chimney Swift occurring at sea except when driven 
there by a gale 1 ‘
