American

Limits.

— A

recent careful examination of the specimen (No. 6072, U.S. Nat. Mus., El Paso, Texas, _J. H. Clark*) on which thesupposedoccurrence ofthis species within our territoryis

based,

shows

thatanerror has been

made

in its identification, it being notthis species atall,buta

young

example ofT. calliofeGould. Should T.heloisa befound withinourlimits,as will doubtless

some

time be the case, it

may

beexpected tooccur

somewhere

along the /owe;-Rio Grande, since it belongs to the moister region of eastern Mexico, the fauna of which is quite distinct from that of the arid central region in which El Paso issituated.

my

collectioneighteen specimens o(Am7nodramiistaken herebetween_{Oct. 4}and _13, 1S90.

Ten

aretrue nelsoni, foursubnirgafus, and theothers intermediates.

They

were found in the

meadows

near the Connecticut River, and seemed partial to certain localities.

The

height ofthe migration was apparentlyon the loth of the

month when

thirteen weresecured,two

more

beingseen thatwere not captured.

On

otherdaysonlyfrom one to three birds couldbe found.

On

the day

when

the larger

number

were killed, the birds appeared

somewhat

stupid,flyingfrom thethick grass

when

disturbed and perch- ingon the wild oatswhere theyremained quiet.

At

other times they werewildanddifficulttoobtain.

American Museum

of Natural History from Mr. E.C.Thurber, contains eleven specimens ofthe bird recently described by Mr.

Anthony

under the above

name

{cf. Zoe, I, 8, p. 23S, Oct., 1890).

An

examination of these specimens during the past

inconnectionwith British

material permits

me

to agree with Mr.

Anthony

as to their distinctness from the dark coast form, yiinco hyemalis oreg07ius. Mr.

Anthony,

however,has

made

no

parison witha
