. Snoutis long, thin, and flexible. Hair is long (up to 17 mm), soft, and silky. Dorsum is brown-gray and slightly darker than that of the Namib Round-eared Sengi (M. flavicaudatus). Lateral pelage is also brown-gray but with yellow tinge. Venter is off-white. Tail hairis very short except for terminal tuft; tail color continues brown-gray of dorsum but becomes slightly darker toward tip. Hair color on head and face is similar to dorsum and flanks. There is no distinct eye-ring as seen on many species of soft-furred sengis. Skin color of pinnae and limbs is nearly black. Females have two anterior, two intermediate, and two posterior nipples; males have no nipples. Five digits are present on each manus and pes. Pectoral gland is absent, and subcaudal gland is present. Dental formula is 1 3/3, C 1/1, P 4/4, M 2/2 (x2) = 40. Molariform teeth are more hypsodont in species of

Arid to semiarid gravel or compact sandy plains with scrub and scattered low bushes. The Karoo Round-eared Sengi shelters in patches of vegetation, shallow selfdug burrows, or abandoned rodent burrows.

The Karoo Round-eared Sengi is omnivorous and feeds primarily on insects and secondarily on herbage, with trace quantities of seeds and fruits. Diets vary seasonally and individually but generally contain 46-88% insects. Consumption of herbage is highest in winter. Relatively long cecum and more hypsodont dentition of species of

|
||
The Karoo Round-eared Sengi is monogamous. Breeding occurs yearround, but most pregnancies are during summer. Gestation is c¢.56 days. Females can produce 21 or more ova per ovary per cycle, but limited uterus implantation sites constrain litter size. Litters have 1-2 young, rarely three. Estrous cycles are c.10 weeks. Young are highly precocial at birth, with eyes open and mobility shortly after birth. Nursing occurs infrequently, perhaps once a day, and lasts c.2 weeks. Mothers provision their young with insects collected in their cheeks beginning at the end of the first week postpartum until the third week. There is no direct paternal investment. No species of soft-furred sengis use nests to shelter or for rearing their young.

Karoo Round-eared Sengis are fully terrestrial. Activity is mainly crepuscular, with some nocturnal tendencies. Diurnal activity is very limited.

|
||
Home ranges of monogamous pairs of Karoo Round-eared Sengis overlap. Proportion of overlap probably depends on densities in suitable habitat. Average home range is conservatively estimated at c.1-3 ha. Each member of a male-female pair probably spends most ofits time independently. Combined home ranges of male-female pairs generally do not overlap with ranges of neighboring pairs. Foot drumming might be limited compared to other species of soft-furred sengis. There is no evidence that trails are built or maintained.
