told that in the vicinity of Mission, Texas, two was the usual
number "born in May and June." Sherman (1945:194) reported a female
with young (number not given) taken on June 7, 1918, at Seven Oaks,
Florida, and another with three young taken on June 20, 1941, at Ocala,
Florida. Lowery (1936:17) recorded a female, having three young,
obtained on June 17, 1932, at Baton Rouge, Louisiana. A specimen taken
on May 19, 1940, at Baton Rouge contained three embryos. Baker and
Dickerman (_loc. cit._) reported four adult females from Veracruz as
lactating on July 22, 1955, but they were accompanied by flying young
of the year and probably were near the end of the lactation period.
Among specimens examined, juveniles are available by date as follows: 5
mi. N Baton Rouge, Louisiana (June 26, 1953); Palm Beach, Florida (July
6, 1950); and Izamal, Yucatan ("taken with mother" on July 28, 1910).
Breeding probably takes place in autumn and winter; Sherman (_op.
cit._:196) reported males from Florida as sexually "mature" from the
beginning of September to mid-February. Late winter segregation of
sexes has been reported.

_Subspecies_

In the following accounts, localities of occurrence in each state are
listed from north to south; if two lie in the same latitude, the
westernmost is listed first. Localities that are italicized are not
shown on the distribution map (Fig. 2), either because undue crowding
of symbols would result or, in several cases, because we could not
precisely place the localities. Length of forearm is the average of
both forearms in individuals in which both forearms could be measured.
