Since the small sample of the new species contained a juvenile, subadult and two adults, it was possible to be confident that the specimens did indeed represent an unde- scribed species.

Scale 1 mm. illustrated the deciduous and adult dentitions of most species. Since the small sample of the new species contained a juvenile, subadult and two adults, it was possible to be confident that the specimens did indeed represent an unde- scribed species. MacPhee suggested the existence of growth curves, unusual in mammals, in which some subadults may exceed the average size of adults. This feature may be indicated by M. dryas, in which both the juvenile and subadult specimens are slightly larger than the adults in head and body length, although the small sample size precludes any meaningful comparison. MacPhee divided the genus into six 'clusters' on the basis of dental traits and body proportions; he emphasised that this was a phenetic, not a phylogenetic arrangement. On the basis of the characters employed by MacPhee, M. dryas groups with the cowani and the gracilis clusters and is intermediate in many features between M. thomasi and M. gracilis. Since M. thomasi, M. gracilis and M. dryas are known from such small.
