NEW OR RARE BIRDS FROM WESTERN COLOMBIA. '\^/ ^ BY OUTRAM BANGS.

The

birds

mentioned below were contained

in a

second

collec- tion*

from western Colombia made by Mervyn G. Palmer, which

I received

from Mr. W.

F.

H. Rosenberg

last

summer

but only

just

now have had time

to touch.

The

_region

Mr.

Palmer has been working

^{in is}

a very

rich one,

and both

collec- tions sent

me by Mr. Rosenberg have

fairly

astonished me

in the

numbers

of rare

and new forms they contained.

Following

are short descriptions ^of the

new forms

in

the

present collection,

and mention

of a

few other

_species

where ranges

^are

extended

or

the

record is

apparently worth pub-

lishing.

Botaurus

From

^A',

nana

(Lawr.), which

it

somewhat

resemblesin general coloration, the

new

form can at once be told

by

having ^the middle of back _distinctly

marked

with _{pale shaft} lines bordered by black, by ^the striping of the cliest being wider, the stripes

more

distinctly bordered by black,

_by the _belly being ^less indistinctly striped.
