Means lengths of limb bones (in mm) are humerus, 35-5; radius, 39; ulna, 48-7; femur, 58-2; and tibia, 68-2. Vertebral formula is 7 cervical, 13 thoracic, 6 lumbar, 2 sacral, and 20 caudal (48 vertebrae). The Short-tailed

Females have one pair of inguinal and two pairs of lateral thoracic mammae. Neonates can eat plant food, which creates a smooth transition during weaning at c.6 weeks.
