Notes on Marsupialian anatomy. I. On the condition of the median vaginal septum in the Trichosuridae.

There has been at various times some little discussion on the state of the median vaginal septum in various members of the genus Trichosurus; up to the present however, the only member of the group which seems to have been examined is the common phalanger Trichosurus vulpecula.
Brass (1) in 1880 described the organs of this animal, and in his specimen found the two median cul-de sacs separated from one another by a complete partition.
In 1899 Forbes (2), in a foot note on a communication on the anatomy of the Koala, speaks of the median vaginal apparatus as a "common vaginal chamber formed by the coalescence and fusion of the two diverticula present in Phascolomys and Phascolarctos." Includes plates.
