PARTDJE — PARINJE: TITMICE. 273 



with little or no brownish tinge. Size slightly larger than that of the typical form ; wing 2.70; 

 tail 2.64 ; tarsus 0.67. Type locality, Field, British Columbia ; range extending in the Rocky 

 Mts. from Liard River S. to Montana. Rhoads, Auk, Jan. 1893, p. 213 ; A. 0. U. List, 2d ed., 

 1895, p. 310, No. 740 b. 



P. h. evu'ra. (Gr. cu, well; ovpa, tail.) Well-tailed Titmouse. Alaskan Chickadee. 

 Like P. hiulsonicMs in color; larger, with especially longer tail; tail nearly 3.00. The varia- 

 tion in this case corresponds to that of P. septentrionalis as compared with P. atricapillus. 

 CouES, Key, 2d ed., 1884, p. 267 ; not recognized in A. 0. U. Lists. 



P. cinc'tus alascen'sis. (Lat. cinctus, girdled, from cingo, I bind about ; alascensis, of 

 Alaska.) Siberian Titmouse. In general, similar to P. hudsonicus, but quite distinct. 

 ^ 9 , adult : Throat sooty-blackish ; crown and nape dark hair-brown, bordered laterally with 

 dusky, appreciably different in tone from the brighter brownish of back, from which also sepa- 

 rated to some extent by whitish of cervix. Sides of head and neck pure white, in a large area 

 widening behind, this white of opposite sides nearly meeting across cervix. Back ashy over- 

 laid with flaxen-brown ; rump light brown with much concealed white. Under parts whitish 

 centrally from the black throat, but heavily washed on sides, flanks, and crissum, sometimes 

 quite across belly, with light brownish. Wings and tail slate-color, as usual in the genus, with 

 much whitish edging, especially on secondaries. Bill plumbeous-blackish ; feet plumbeous. 

 Length 5.30-5.60; wing 2.60-2.80; tail rather more; tarsus 0.65. Eggs 0.65 X 0.50. A 

 large stylish Chickadee, lately ascertained to inhabit Arctic America, especially Alaska. It is 

 very near the E. Siberian form of the Lapp titmouse (true P. cinctus of Boddaert, P. sibiricus 

 Gm., or P. lapponicHS Lundahl), from which P. ohtectus Cab., J. f. O., 1851, p. 237, is by 

 some considered specifically distinct. Compare Pcecila submicrorhynchus of Brehm, Nau- 

 mannia, 1856, p. 369. Our Alaskan bird is P. cinctus of former eds. of the Key ; P. c. obtectus 

 Ridgw., Pr. U. S. Nat. Mus., viii, 1885, p. 354 ; Man., 1887, p. 564 ; A. 0. U. Lists, 1886 and 

 1895, No. 739; name now changed, after Pcecila cincta alascensis Prazak, Orn. Jahrb., 

 Mar.-Apr. 1895, p. 92, to Parns cinctus alascensis, A. 0. U. Suppl. List, Jan. 1897, p. 132, 

 No. 7.39. 



PSALTRIP'ARUS. (Gr. -^aXTpia, Lat. psaltria, a lutist; parns, a tit.) Bush-tits. 

 Dwarfs among pygmies! 3.75-4.25 long; wing 2.00 or less, tail 2.00 or more. Ashy or 

 olive-gray, paler or whitish below ; neither crown nor throat black ; no bright colors. Head 

 not crested ; wings rounded, shorter than the long narrow graduated tail. Nest large, woven, 

 pensile, with lateral entrance (fig. 134). Eggs 6-9, white, unmarked. The 4 species are 

 Western ; they are notable for their diminutive size, scarcely equalling a Polioptila in bulk.
