TROGLODYTID^E—TROGLODYTIN.E: WRENS. 295 



below; flanks as well as crissuin barred with dusky; tail-bars bi-okea up intu irregular nebu- 

 lation. Valley of the Rio Graude; a local race of N. E. Mexico, which is admitted in neither 

 of the A. 0. U. Lists, 1886 and 1895, perhaps as being extralimital, or iu some uncertainty 

 regarding its subspecitic status. But it seems to be as well marked as the others, and for the 

 ])resent I let it stand, as in all the previous eds. of the Key. 



THRYO'MANES. (Gr. Bpvov^ thruon, a reed; fidvrjs or fiavrjs, manes, a kind of cup.) Be- 

 WK'k'.s Wkens. Similar to Thryothorus, but tail not decidedly shorter than wings — usually 

 decidedly longer — blackish, not fully barred. Coloration not reddish-brown above. (Included 

 under Thryothorus in former eds. of the Key, and in A. O. U. Lists till 1899.)

T. be'wicki. (To Thomas Bewick.) Bewick's Wren. Above, dark grayish-brown ; 

 below, ashy-white, with a brownish wash on flanks. Rump with concealed whitish spots. 

 A long whitish superciUary stripe from nostrils to nape. Under tail-coverts dark-barred; two 

 middle tail-feathers like back, with numerous fine black bars; others black with whitish mark- 

 ings on the outer webs and tips. Length about 5.50 ; extent 6.75 ; wing 2.00-2.12 ; tail 2.35; 

 bill 0.50; tarsus 0.75. Eastern U. S., southerly, N. to the Middle States and Minnesota, W. 

 to the edge of tlie Great Plains ; resident iu most of its range. Not very common in the Atlan- 

 tic States, but so abundant as to replace the House Wren in some parts of the interior. Nest 

 in holes in trees, stumps, fences, etc.; eggs 5-9, 0.65 X 0.50, white, finely dotted and spotted, 

 resembling those of Catherpes or Salpinctes. 



T. b. leucogas'ter. (Gr. XeuKoy, lei(kos, white; yacm'jp, gaster, belly.) Baird's Wren. 

 White-bellied Wren. Above, uniform clear ashy-brown ; below, clear ashy-white ; pure 

 white on middle under parts. A long, strong, wliite superciliary stripe ; auriculars speckled 

 with white. Concealed white spots on rump. Quills of wings fuscous, the inner ones very 

 obsoletely waved with color of back. Two middle tail-feathers closely barred with pure dark 

 ash and black well contrasted with the ashy-brown of the back ; others black, with irregular 

 white or asliy-white tips ; outer web of exterior one barred with white. Length 5.50-5.75 ; 

 extent 6.75; wing 2.00-2.33; tail 2.25-2.50; bill 0.50; tarsus 0.75. A well-marked 

 geographical race, inhabiting tlie Great Plains and Great Basin, from Kansas and Colo- 

 rado to Utali, Texas, New Mexico, Arizona, California, E. of the Sierra Nevadas, and 

 S. into Mexico. Thryothorus (Thryomanes) bewickii, var. leucogaster Bd., Rev. A. B., 

 1864, p. 127 (not Troglodytes leucogastra of Gould, P. Z. S., 183(5, p. 89, as Baird supposed 

 it was, for Gould's bird is uropsila leucogaster of ScL. and Salv., Cyphorhinus pusillus ScL., 

 Heterorhina pusilla Bd.); Thryothorus bairdi Salv. and Godm., Biol. Cent. -Am., i, Apr.

 Lists, 1886 and 1895, No. 719 b ; but no rule of nomenclature requires us to change the sub- 

 specific name leucoaaster Bd., 1864. The fact that Troglodytes leucogastra Gould, 1836, is 

 an entirely diS'erent bird, belonging to another genus, does not outlaw Thryothorus bewicki 

 leucogaster, or in any way aff"ect nomenclature in the genus Thryothorus. See Coues, Auk, 

 Oct. 1896, p. 345. The point is conceded in A. 0. U. Suppl. List, Auk, Jan. 1897, p. 131, 

 where the Key name is restored, as above. 



T. b. spilu'rus. (Gr. ottCKos, spilos, s\)oncd; ovpa, ourn, tail.) YiGORS' Wren. Speckled- 

 tailed Wren. Similar to T. bewicki in color ; upper parts more uniform dull bistre rather
