Morelos, Hooper (Jour. Mamm., 28:43, February 1, 1947)
lists a specimen, as he says, on purely geographic grounds, as of the
subspecies _Didelphis mesamericana tabascensis_. We have examined this
specimen, an unsexed skull-only, which falls within the range of
individual variation of _Didelphis marsupialis californica_ and refer
the specimen to that subspecies.

~Didelphis marsupialis etensis~ J. A. Allen

From El Muneco, Costa Rica, Harris (Occas. Papers, Mus. Zool. Univ.
Michigan, no. 476:7, October 8, 1943) lists as _Didelphis richmondi_ a
specimen ([Male], No. 67550 U.M.). Our examination of the specimen
shows it to be within the range of individual variation of populations
that have been referred to _D. m. etensis_ from adjoining areas. We
identify the specimen as _Didelphis marsupialis etensis_.

~Didelphis marsupialis tabascensis~ J. A. Allen

From Minatitlan, Veracruz, J. A. Allen (Bull. Amer. Mus. Nat. Hist.,
14:168, June 15) listed a specimen under the name _Didelphis
marsupialis_ [in the trinomial sense] instead of under the name
_Didelphis marsupialis tabascensis_, which would be expected, on
geographic grounds, to apply. The specimen is No. 78123, U.S. Nat.
Mus., Biol. Surv. Coll. Our examination of the specimen reveals that it
is within the range of individual variation of _Didelphis marsupialis
tabascensis_ and we identify the specimen as of that subspecies. From
Yaruca, Honduras, Bangs (Bull. Mus. Comp. Zool., 39:157, July, 1903)
doubtfully listed as _Didelphis yucatanensis_ a specimen, No. 10611,
M.C.Z. Our examination of the specimen indicates that it is within the
range of variation expectable in _Didelphis marsupialis tabascensis_,
known from surrounding areas, and we identify the specimen as
_Didelphis marsupialis tabascensis_.

~Didelphis marsupialis virginiana~ Kerr

J. A. Allen (Bull. Amer. Mus. Nat. Hist., 14:166, May 28, 1901) and A.
H. Howell (N. Amer. Fauna, 45:20, October 28, 1921) have identified
four skulls from Sylacuga, Alabama, as _Didelphis virginiana pigra_.
The two subspecies _virginiana_ and _pigra_ are not known to differ
cranially. We have, however, examined the skulls which are Nos.
44057-44060 in the U.S. Nat. Mus., Biol. Surv. Coll. Because they are
from a place north of other localities (Auburn and Greensboro, Alabama)
from which the subspecies _virginiana_ has been recorded, and within
the geographic range of _virginiana_, we identify the specimens as
_Didelphis
