A relatively small form, designated "Undescribed species A", is similar in size to oryzomyines from Saint Kitts and Anguilla, and a larger form is apparently identical to "Undescribed species B", described from Antigua and other islands. Two other possible species, one larger than the second and the other smaller than the first species, are documented by even more fragmentary material.
