Diagnosis
ReferenceDiagnosis
Osgood 1909Posterior palantine foramina situated farther back than in Peromyscus, being decidedly nearer to the interpterygoid fossa than to the posterior endings of the anterior palatine slits. Molariform teeth relatively wide, and with enamel folds much comptressed; tubercles relatively low; a tendency to development of a raised cingulum marked by subsidiary tubercles in the inner salient angles of M1 and M2; eneamel relatively thicker than in subgenus Peromyscys, the pattern as seen in partly worn teeth being much compressed both laterally and longitudinally, so that the folds of the two sides touch in almost all stages of wear, leaving five subtriangular islands of dentine in M1 and four in M2; lower molars similarly peculiar.
