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

North American Yellow Bats, 'Dasypterus,' And a List of the Named Kinds Of the Genus Lasiurus Gray — Part 10

_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 México, _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_.
