17. Regulus calendula (Linn.) Licht. Ruby-crowned Kinglet.—“Common among the Chiricahua Mountains, especially in deciduous timber. I think a few summer and breed.” The following specimens are identical with eastern ones:

28, ♂ ad., Cave Creek, Chiricahua Mountains, March 8. Length, 4.60; extent, 6.50; wing, 2.32.

122, ♂ ad., Morse’s Mill, March 28. Length, 4.20; extent, 6.90; wing, 2.38.

18. Lophophanes inornatus (Gamb.) Cass. Plain Titmouse.—Mentioned in Mr. Stephens’ notes as rare on the foot-hills of the Chiricahua Mountains, but no specimens are included in his collection.

19. Lophophanes wollweberi Bonap. Wollweber’s Titmouse.—This species was abundant in the Chiricahua Mountains, where a fine series was collected. They were usually seen in flocks of six or eight, and often associated with other small birds. They were rarely met with excepting in the groves of “scrub oaks,” but their food appeared to be wholly insects. A single pair taken in the Santa Rita Mountains in May are unaccompanied by any special remarks.

20. Parus meridionalis Scl. Mexican Chickadee.—In a late number of the Bulletin (Vol. VI, p. 252) I briefly announced this important addition to the North American fauna. The series obtained by Mr. Stephens comprises nine specimens, all of which were taken near Morse’s Mill. They occurred upon the sides or summits of the surrounding mountains, at elevations varying from seven to ten thousand feet, and were usually found in pairs, although they not unfrequently associated with other birds, among which are mentioned Psaltriparus plumbeus, Lophophanes wollweberi, Sitta pygmæa, and Peucedramus olivaceus. They were for the most part silent, but occasionally uttered a “chee-wee-wee,” as well as notes resembling those of P. montanus.

Previous writers have compared this species with P. atricapillus, but to me it seems nearer related to P. montanus. With the latter it agrees in certain peculiarities of size and proportions, while the general coloring and markings of the two are so similar that almost the only appreciable points of difference are presented by the white forehead and head-stripes of montanus. These characters are, of course, enough to instantly separate the birds, but their importance is somewhat weakened by the fact that one of my specimens of meridionalis (No. 124) possesses a head-stripe which, though ill-defined and considerably shorter, is nevertheless similar in appearance and position to that of montanus. While it would be rash to argue any varietal affinity on the strength of this single specimen, the outcropping of such a well-marked characteristic certainly shows a close relationship between the two species, unless indeed No. 124 be regarded as a hybrid.
