Show 140 DR. 3. E. GRAY ON NEW-ZEALAND WHALES. [Jl indicative of a peculiar group, for which I propose the name ol Scapula of Macleayius australiensis (inside). The peculiarity of the genus Halibaleena is that the lateral process of the atlas is broad and expanded, long at the top, and gradually shorter below, with an oblique descending outer margin (see figure, Cat. Seals and Whales, p. 83, f. 3). The upper lateral process of the second vertebra is broad, united to the hinder margin of the atlas; the lower process broad and bent up at the end, nearly as long as the lateral process of the atlas. The upper lateral processes of the third, fourth, and fifth vertebrae small, dilated at the end, and more or less anchylosed; the lower lateral process of each vertebra similar, but much smaller and shorter.
