The

Vespertilio concinnus of Harrison Allen,

Through

^{thekindnessof Mr.}

Witmer

Stone I have recently

had

the opportunity^to

examine

the bats on

which

Harrison Allen based the

name

^I>*//////<;<-<nn'itinu* (Proc.Acad. Nat. Sci. Philadelphia, 18<>(>, p.

280).

The

_specimens,

two

in

number,

^arein alcohol,

and

labeled "San Salvador, Dr. ^J. Leidy."

Though much

fadedincolorthey^are clearly referable _{to Myotitt}nigricanx (Maximilian), oratleast tothatform ofthe speciesoccuring ⁱⁿ

Columbia and

southern Mexico.

The name

<-<irin- nuifis therefore a

synonym

^of nigricann unless the bat ^to

which

it

was

appliedshould_eventuallyprove^tobedistinctfrom the tnie nigricans^of Brazil, specimens^of

which

Ihave not seen. In that case it

would

be tenableforthenorthern animal. GerritN. Miller. Jr.

The

_generic

name _Evotomys

not invalidated by Anaptogonia.

In a

posthumous

paper on^the faunaof the Port

Kennedy

^{b "me iissure} (Journ. Acad, Nat.Sci., Philadelphia, 3d Ser. XI, p. 201)

Cope

^substi tuted the

name

Anaptogonia

Cope

^{1871 basedona fossil}Microtine rodent forEvotomyx Coues1874 originally applied^tothe

Redbacked

Mice.

The

change

was made

on account of the supposed generic identity ^of the fossil

and

living animals.

Through

the courtesy ^of Mr.

Witmer

Slone

I haverecently

had

an opportunity^to

examine two

_specimens of

Anap

togonia

from

the collection of the Philadelphia

Academy

^{of Sciences,} Thismaterial

shows

that Anaptogonia, although provided with ^rooted molars, ^isinno

way

closelyrelatedtoErotoiny*.

The

^{teeth are}aslarge as inMicrotnx_(Xcojiber)alleni,

and

the

enamel

_pattern^ischaracteri/.edby acute angularity.

The

genus thus resembles the 'M/vvVv/W itifrrntnlitrx"

of Xewtori

and

the Doltnnyn^of Xehring. Therefore the

name

Kr<>1<>iui/x asapplied ^tothe

Redbacked Mice

is in no

way

invalidated by the pre vious publication ^of Anaptogonia.^{f-GerritX. \fillrr. Jr.}

Note

on Micronycteris brachyotis (Dobson) and

M.

microtis Miller.

In describing a bat from Greytown, Nicaragua, under ^the

name

M'i- cronycterift microti*(Proc. Acad. Nat. Sci. Philadelphia, 181)8, p. JJ28), ^I

overlookedthefactthat

Dobson had

_previously(Proc. Zool.Sue London, 1878, p. 880) described a

member

of the

same

genus from Cayenne,

French

_Guiana, as Schfuostoma Iradiyoir, a

name

not cited in Ti-oues- sart's 'Catalogus.'

The two

animalsare evidently

much more

distinct from each other than the similarity of their specific

names would

at first suggest. Aficronycteris l>r<i<-/it/<>tix is, with the exception ^{of J/,} beknii,oneof the _largestspecies ^of the genus (forearm 40 mm.), while'

M.

microtix is

among

the smallest (forearm HI). In M. hrm-htinti* ^the-

( rI- 1 1 1-I'llI Xnti'X. 1")")

upright portion ^of the noselcaf is

"much

narrower than the horse shoe,"

and

the prominences on ^the chinareof very peculiar form. In

M. inicrotixthe upright portion ^of the noseleaf is fully as wide as the 'horse-shoe,'

and

theprominences onthe chin are exactly^{as in} normal

members

of the genus. ^{(1errit S.} \nilcr,Jr.

The

_systematic

name

of the

Cuban

red bat.

In

Ramon

do la Sacra's IlistoriaFisica PoliticayNatural<lela Islade Cuba, III, p. '>2, 1845, Gervais describes the

cuban

red bat as Vesperfilio hluxitcrittii. Publicationof the

name

heattributestoLesson

and

_Garnot,

"Bull. Sc. Nat. VIII, p. 95." This reference I have not been able to verify, but it unquestionably antedates the publication ^of Gundlach's

name

Atnln/i/tfi iift'ifferi (18til) by ^sixteen years.

The

animal should thereforebe

known

as Luxinnixhlnxxt-rinii. (icrrit N. Miller, Jr.

Note

on the Vespertilio blythii of

Tomes.*

In 1857

Tomes

published^adescription^of the Indian representative^of Mt/nti* myotix under the

name

Vespertilio blythii (Proc.Zool. Hoc.

Lon

don, 1857, p. 53). Recent authors have without _exception regarded ^the animalas identicalwiththe

European

^form.

A

_specimencollectedby^Dr.

YV. L. Abbott in

Kashmir

Museum)

shows, however, ^thatthisviewisnot _correct,

and

that Myotix blythii^isa well characterized species, readily distinguishable from M.

iitynfixhy ^itsshorterears,

much

smaller audital bulhe,

and

_byapeculiar ity in the formof the maxillary ^{molars. In} these teeth the protocone

is lower and further

removed

from the paracone than ⁱⁿ M. _myotix, a character

which

is at once appreciable

when

the teeth of the

two

species are viewed in profile from the front. This peculiarity ^{is evi-} dently ^ofconsiderable importance, ^asIcan findnoappreciable variation in the form of the molars

^a large
