CHAMPA FASCIATA AND ITS SUBSPECIES.

H.

OSGOOD.

Among ^{the Wren-Tits}

ⁱⁿ the collection of

the

U. S.

National

Museum*

^is

a

_single

specimen (No. 3339) which formed

_{part of}

the

_original

Baird

collection

and which

^is labeled in Prof.

Baird's

writing

'

Parusfasdatus

California,

Wm. Gambel.'

Tin's is the

only known _specimen

of

Champa

collected

by Gambel, and

as

such Mr. Ridgway ^has

^for

some time considered

it the

type

^of

Chamxa _fasdata Gambel. The exact

_locality

from which

it

came

is

unknown but

itscharacters

show conclusively

^thatit

belongs

^to

the

_pale

southern form

rather

than

to

the dark north ern

one.

This being

^the case,

Chamssa

_f.

henshawi becomes a

synonym

^{of C.} fasdata,

and

it is

necessary

^to

provide a new name

for

the northern

coast

form

heretofore

assumed

to

be

typical fasdata.

The

status of

the two forms may ^be summa

rized as follows:

Chameea

fasciata

Remarks.

The

type^ofC. fasciata,thoughslightlydarker thanthetype of^'hensli'iwi,'exactly represents the average condition of the southern

and

interior form. Specimens from ^the Sacramento _Valley, from

San

Bernardino county

and

Pasadenado notdifferfromitin

any

way. ^Itis possible thatthe type

was

takenin

San

Bernardino County,^sinceitagrees perfectly with specimens from ^there

and Gambel must have

_passed throughthatregion.

Even

ifthe type

were

not available it

would

be besttouse the

name

forthe southernform, since ^{so far as}

known, Gam-

bePs collecting in California

was

confined to the region south of

San

Francisco.
