 The oryzomyines of the Caribbean were revised in 1962 by Clayton Ray, who examined the specimens Gregory had found and redescribed them.He suggested that "M. audreyae" may in fact have come from Barbados instead of similarly named Barbuda, citing the occurrence of a different oryzomyine (""Ekbletomys hypenemus"") in other cave deposits on Barbuda, circumstantial evidence for the occurrence of a native rodent on Barbados, uncertainty whether Gregory ever visited Barbuda, and biogeographical considerations.In the subsequent literature, "M. audreyae" has seldom been mentioned and never been further described.
