In listing the subspecific names given immediately above we are aware of the possibility that a thorough study of the geographic variation in Didelphis marsupialis may contract or expand the list of recognizable subspecies. We are aware also that Hershkovitz (Fieldiana: Zoology, 31 (No. 47):548, July 10, 1951) has arranged several of the subspecific names listed immediately above as synonyms of Didelphis marsupialis californica Bennett. We have not employed his arrangement because he has not given proof that the currently recognized subspecies are indistinguishable.

~Caluromys derbianus canus~ (Matschie)

Matschie (Sitzungsberichte der Gesellschaft Naturforschender Freunde zu Berlin, Jahrgang 1917, p. 284 (for April), September, 1917) applied the name Micoureus canus to a specimen on which the locality was no more precise than Nicaragua. Comparison of Matschie's description with specimens in the United States National Museum (including the holotype of Philander centralis Hollister and referred specimens of Philander laniger pallidus Thomas) reveals that Matschie's specimen was intermediate in coloration between the other two kinds of woolly opossums named above and that there is nothing distinctive, in the specific sense, in the cranial measurements which Matschie published (op. cit.). M. canus, therefore, may be merely an intergrade between the two previously named woolly opossums (C. d. centralis and C. d. pallidus), an individual variant of a previously named kind, say, C. d. pallidus, or a valid subspecies. If it is a recognizable subspecies, it probably comes from somewhere in the eastern half of Nicaragua. As a means of handling the name, Micoureus canus Matschie, we tentatively place it as a subspecies of the species Caluromys derbianus. The name may, therefore, stand as Caluromys derbianus canus (Matschie), with type locality in Guatemala.
