Range.--"Breeds in Transition Zone of the coast belt in California from northern Trinity County to southern Monterey County; south in migration to Lower California and Sonora" (A.O.U.).

=759e. Sierra Hermit Thrush= (_H. g. sequoiensis_). Similar in coloration to _H. g. slevini_, but decidedly larger and slightly darker or browner; similar to _H. g. guttata_, but larger, paler, and grayer; decidedly smaller." W. 3.65; T. 2.82. (Ridgway).

Range.--"Breeds in Boreal Zones from southern British Columbia to high mountains in southern California; south in migration and in winter to Lower California, western Texas, and northern Mexico" (A.O.U.).

Page 239. Cancel 758b, Monterey Thrush, and No. 758c, Alma Thrush, which are now considered to be the same as No. 758, Russet-backed Thrush.

Pages 240 and 241. The decisions of the A.O.U. Committee on numerous proposed changes in the standing of our Juncos were not published until after the first edition of the Color Key appeared. One new form (No. 567h) has been added to those therein given one (_J. o.

shufeldti_) has been omitted and the following changes have been made in nomenclature:

No. 568. _Junco mearnsi_, becomes No. 567g, Junco hyemalis mearnsi, and the Range of this form is now given as "Rocky Mountain region.

Breeds from southwestern Saskatchewan to southern Idaho and northern Wyoming and Colorado to southern Arizona, southern New Mexico, and northeastern Sonora" (A.O.U.).

No. 567.1 _Junco monta.n.u.s_, becomes No. 567f. _Junco hyemalis monta.n.u.s_.

No. 571.1 _Junco townsendi_, becomes No. 567i, _Junco hyemalis townsendi_.

No. 569 _Junco caniceps_, becomes No. 570b. _Junco phaeonotus caniceps_.

No. 570a. _Junco dorsalis_, becomes _Junco phaeonotus dorsalis_.

No. 567a. _Junco orega.n.u.s_, becomes _Junco hyemalis orega.n.u.s_.

No. 567c. _Junco orega.n.u.s thurberi_, becomes _Junco hyemalis thurberi_.

No. 567d. _Junco orega.n.u.s pinosus_, becomes _Junco hyemalis pinosus_.

The common names of all the preceding species remain unchanged.

No. 567b. Coues' Junco (_Junco orega.n.u.s connectens_) becomes Shufeldt's Junco (_Junco hyemalis connectens_), and this form also includes _J. o. shufeldti_ of the 'Color Key,' which is therefore cancelled. The Range of 567b, thus stands as follows:

Rocky Mountain region. Breeds from the coast of southern British Columbia east to west, central Alberta and south to northern Oregon; winters over entire Rocky Mountain tableland to eastern Colorado, Arizona, New Mexico, western Texas, Chihuahua, and Sonora; casual in northern Lower California" (A.O.U.).

The one new form added follows No. 568. after which insert =567h, Ridgway's Junco= (_J. h. annectens_). Back with a reddish brown patch as in _J. p. caniceps_, but sides washed with pinkish brown, as in _J. h. mearnsi_.

Range.--"Wyoming, Colorado, Arizona, and New Mexico" (A.O.U.).

Page 242. Cancel No. 744.1, Santa Rita Bush-t.i.t, which proves to be the same as No. 745, Lloyd's Bush-t.i.t.

Page 243. Cancel No. 731a, Texan Tufted t.i.tmouse, which proves to be the same as No. 731, Tufted t.i.tmouse.

Page 243. After No. 732 add: =732a. Sennett's t.i.tmouse= (_B. a.

sennetti_). "Similar to _B. a. atricistatus_, but decidedly larger; upper parts much clearer gray, with little, if any olive tinge; adult female with crest feathers more often and more extensively tipped with gray, and both s.e.xes with the forehead more often tinged with brown or rusty, sometimes deeply so" (Ridgway).

Range.--Central Texas, "from Tom Green and Concho Counties east to the Brazos River, and from Young County south to Nueces and Bee Counties"

(A.O.U.).

Page 244. After No. 741b. add: =741c. Valdez Chestnut-sided Chickadee= (_P. r. vivax_). Like _P. r. rufescens_ in coloration but larger, tail proportionately longer and bill bulkier. W. 2.48; T. 2.32 (Grinnell).

Range.--Prince William Sound Region, Alaska.

Page 244. Cancel 740a. Kowak Chickadee, and No. 740b, Columbian Chickadee, which prove to be the same as No. 740, Hudsonian Chickadee.

_Parus h. littoralis_ becomes No. 740a, Acadian Chickadee.

Page 244. After No. 738 add: =738a. Bailey's Mountain Chickadee= (_P. g. baileyae_). Similar to _P. g. gambeli_, "but coloration dorsally and laterally more plumbeous, less brownish, and bill larger." B. 41 (Grinnell).

Range.--"Mountains of Great Basin region and northern Lower California. Breeds in Canadian and Transition Zones from the Maury Mountains, Oregon, south over Nevada and eastern California to the San Pedro Martir Mountains, Lower California" (A.O.U.).

impiger_). Similar to _P. c. carolinensis_ but darker and decidedly smaller (except bill). W. 2.08; T. 1.81; B. .31 (Ridgway).

Range.--East central Florida.

Page 245. After No. 735b add: =735c. Yukon Chickadee= (_P. a.

turneri_). "Similar to _P. a. septentrionalis_ but slightly smaller, coloration grayer above and more extensively or purely white beneath, and white edgings of greater wing-coverts, secondaries, and outermost rectrices broader, more purely white" (Ridgway).

Range.--Alaska, north and west of Cook Inlet.

Page 248. After No. 622c add the northeastern form of the Loggerhead Shrike, which is intermediate between _L. l. ludovicia.n.u.s_ and _L. l.

excubitorides_ and has been separated as =622e. Migrant Shrike= (_L.

l. migrans_). Similar to _L. l. ludovicia.n.u.s_ but bill smaller and colors averaging paler. Not so pale as, and lacking the whitish upper tail-coverts of _L. l. excubitorides_.

Range.--"Eastern North America. Breeds chiefly in Transition and Upper Austral Zones from northern Minnesota, Wisconsin, Michigan, southern Ontario, southern Quebec, Maine, and New Brunswick, south to eastern Kansas, southern Illinois, Kentucky, western North Carolina and interior of Virginia (locally in the east); winters from Middle States and southern New England to Texas, Louisiana, and Mississippi"

(A.O.U.).

The Range of the Loggerhead Shrike (No. 622) is therefore restricted to the South Atlantic and Gulf States from southern North Carolina south through Florida and west to Louisiana.

Page 250. After No. 612 add: =612a. Lesser Cliff Swallow= (_P. l.

tachina_). Similar to _P. l. lunifrons_ but decidedly smaller, the forehead ochraceous instead of cream color. W. 4.08; T. 1.77 (Oberholser).

Range.--"Texas and Mexico. Breeds in western Texas, the Rio Grande Valley, and through eastern Mexico to Vera Cruz" (A.O.U.).

Male much like the female of _P. subis_ but brighter, more uniformly steel-blue above. Female like female of _P. subis_ but brighter, more uniformly gray, the belly whiter, without black shaft streaks; the nape without sign of a collar in either s.e.x. W. 5.2.

Range.--Breeds from Lower Rio Grande in Texas south to southern Brazil.

Range.--"San Antonio, Texas, south through eastern Mexico, Yucatan and central America to Panama" (A.O.U.).

The Range of No. 496 is hence restricted to the region from northwestern Mexico to southern Arizona.

Page 255. After No. 488a. add: =488b. Western Crow= (_C. b.

hesperis_). Similar to No. 488 "but decidedly smaller, with bill relatively smaller and more slender." [Male] W. 11.88; T. 6.72; B. 1.87; depth of B. at nostril .62 (Ridgway).
