Lasiurus intermedius insularis, new subspecies

_Holotype._--Adult female, preserved in alcohol but having skull
removed, formerly in the Poey Museum, University of Havana, now No.
81666, Museum of Natural History, University of Kansas, from
Cienfuegos, Las Villas Province, Cuba; obtained on January 23,
1948, by D. Gonzales Munoz.

_Geographic distribution._--Known only from the island of Cuba (see
Fig. 2).

_Diagnosis._--Large throughout (see measurements); sagittal crest
enormously developed, especially posteriorly (height above
braincase averaging 1.7 mm. in 4 specimens); interorbital region
narrow; M3 narrow; mesostyle of M1 and M2 and 2nd commissure and
cingulum of M3 small; pelage yellowish to reddish-brown.

_Comparisons._--From _Lasiurus intermedius intermedius_ of the
adjacent mainland of Mexico, _L. i. insularis_ differs as follows:
Larger, both externally and cranially; sagittal crest relatively
higher, especially posteriorly; interorbital region relatively
narrower; palate longer posterior to tooth-rows; teeth distinctly
larger throughout except M3, which is relatively (frequently
actually) narrower, averaging 66.1 (62.5-71.0) per cent width of M2
in _insularis_ rather than 74.1 (66.6-79.3) per cent in 10
_intermedius_ from Brownsville, Texas; mesostyle of M1 and M2
relatively smaller as are second commissure and cingulum of M3;
coloration of No. 254714 USNM resembling that of _L. i.
intermedius_, but coloration of three specimens, preserved in
alcohol, averaging somewhat darker (more reddish-brown) than in
_intermedius_.

From _Lasiurus intermedius floridanus_ of the adjacent Floridan
mainland, _L. i. insularis_ differs in many of the same ways that
it differs from _L. i. intermedius_, except that the differences
are even more trenchant bec
