Glossophaga

G.
soricina
andG.
commissarisi
from Guatemala, and Jones and Carter (1976) indicated that G.
alticola
occurs in Guatemala.
Critical comparisonsof ofthese three specieshave not been published andour attempts to TODO identify specimens with the aid ofofGoodwin's (1969)key and descriptions were not TODO J. K.Jones,Jr.,kindly loaned uscopies offigures TODO andmeasurements that he has used to guish the three species.With this aid,Koopman identified all of thespecimens
of
from Guatemala that arein the TODO AMNH.In G. alticola,
the
diagnostic character ofthe elevated TODO braincase(Goodwin,1969 1969)was difficult to use in view ofits variability in
soricina
andcom-
TODO
TODO missarisi
. However,
alticolacan
be distinguishedfrom each ofthe other species because it TODO combines their two most diagnostic characters.The premaxillaries,asnoted byGardner (1962) TODO in the descriptionof ofcommissarisi,
form
a shallow arch infront ofthe canines (when viewed TODO from above) in
alticolaand
commissarisi
,as opposed tothe more projecting and angular pre- TODO maxillariesofsoricina.

Glossophaga
were found roosting with
Saccopteryx bilineata
ina hollow tree,in ina pure colonyof ofmore than 30 individuals in a culvert, in small numbers (1-4) in culverts with
Macrophyllum
and
Carollia
, and ina TODO protected cavity undertree roots along aditch.Of 1,082 bats netted during Julyand TODO TODO August 1977, 60 (5.5%) were
Glossophaga
; specific identifications were not made in the field.
Guatemalan records basedon specimensinthe TODO American Museum ofNatural History that TODO pertain to

listed in the correspondingspecies accounts.Seven TODO specimens from La Avellana, depositedat the USNM have not been reexamined byus. G. TODO TODO
