7. EUTROPIA.

Eutropia, Gray, l. c. p. 262; P. Z. S. 1866, p. 215; Synops. Whales & Dolph. p. 7.

Beak of the skull only rather longer than the brain-case. Skull depressed, thick, with the sides rather bent down behind the notch. The beak depressed, broad, rounded on the sides, rather longer than the length of the brain-case; the intermaxillaries flat, rather broad. Teeth small, slender, five or six in an inch.

The skull bears a considerable affinity to the skulls of Phocæna, Neomeris, Beluga, and Monodon in the bending down of the sides.
