Color.

— ^The

^{color of}

much

like that of T. cas- lioica. that

no

throughout

a

shade

lighter except

on

there is

an

The

colorof the

and

to well

between

the eyes in

The

tail of T. castanea isbrighter in color

than

that of T. siaca

arc distinctly smaller

Two specimens from Aru Bay and two from

specimens from

farther

down

the coast

and

the adjacent islands.

— ^Similar

^{in all} respects to

Niadias

princeps (Miller)," except in size,

being

distinctly smaller throughout. Fore-

arm

72

mm.,

instead of 84.4.

Color.

— The

color of

Niadias minor

is

apparently

not essentially different

from

that of ^{^V.} princeps. It is rather lighter

throughout and

less yellowish

on

the underparts,

perhaps due

to its preservation in alcohol

and

the fact that the hair is rather scant

above owing

to sloughing.

The

fingers, the elbows,

and

the distal two-thirds of the

forearms

are whitish in color.

The antebrachium near

its attach-

ment

to the body, the

wing membrane between

the

forearm and

the fifth finger,

and

the tips of the

wing

are also whitish.

Some

of this

may

be

due

to

sloughing

ofthe

dark

epidermis, but as this

whitening

is

symmetrical on

both sides of the

body

it is probabl}'^ natural.

Skull and

teeth.

— ^The

^skull

^and

^{teeth of}

^{Niadias minor}

are similar in every

way

to those of

N.

princeps.^ except in size. See

below.

The Sumatran

that the single available

From an examination

of its finger joints its

immaturity

is scarcely noticeable.

The

however, shows unmistakable
