moderately long; it tapers from before backward, and has a stout, blunt, bifid, posterior termina- 
tion. The anterior face is broadly triangular, the base of the triangle (forming the superior portion 
of the neural arch ) being straight. The spine is concave below and grooved throughout its extent ; 
the triangular portion of it overshadowing the arches of the third and fourth vertebrae. The 
pedicels of the axis are very slender. 
The centra of the third and fourth vertebra are coossified, but not the arches. The summit of 
the arch in the third is incomplete in this specimen, and the pedicels in this and the succeeding 
cervicals are slender and compressed. In the third and fourth, the superior transverse processes 
are only slightly indicated, and the inferior are absent ; the centra are slightly pointed below and 
flattened above, though generally rotundate. 
The fifth and sixth cervicals are ankylosed by their centra and inferior transverse processes, 
and the sixth by its centrum to the seventh cervical, forming the third mass previously mentioned. 
In the fifth and sixth, short inferior transverse processes are develoj>ed, though the superior 
ones are insignificant. The centra are more squarely shaped than in the preceding. There are 
no spinous processes, but the superior portion of the arches is rather pointed. The planes of the 
zygapophyses are nearly horizontal, and the arches are not coossified. The pedicels of the seventh 
cervical are much broader, and long recurved superior transverse and spinous processes are devel- 
oped, though the inferior transverse processes are barely indicated. Two rounded knobs, which 
are nearer the summit of the centrum than the processes of the preceding cervicals, serve as points 
of articulation for the head of the first rib. In the first thoracic, this tubercle appears to be 
missing, though it re -appears on the second. Both the first and second thoracic have strong, 
stout, superior transverse processes, with large and prominent facets for the tubercular articulations 
of the ribs. The vertebrae rapidly increase in size and the spinous processes in length, and the 
centra assume a more rounded outline. 
Two specimens of this species were obtained October 29th, 1872, by Captain C. M. Scammon. 
The entire skeleton of one specimen, and the skull and cervical vertebrae of the other, above 
described, were preserved. The former is now in the Mus. S. I. Of the species included under 
the genus Delphinus, as restricted by Gray (Supl. Cat. 1871, pp. 68-9), D. lungiroslris is entirely 
black, of different proportions, with the posterior part of the palate keeled instead of grooved, and 
the triangle extending only to the tooth line instead of beyond it. (Reported from Japan.) D. 
major has the grooves on each side of the palate, " veiy wide and rather shallow, scarcely extend- 
ing behind the hinder half of the beak." (Habitat unknown.) D. Forsteri is differently colored 
and proportioned. (Norfolk Island.) D. obliquidens, Gill, belongs to another genus. The remain- 
der are all Atlantic species. 
Of other species of unknown or Pacific habitats, which have been described from drawings, or 
of which the skull is unknown, and to some of which this species might be suspected to belong, 
D. Novcb Zriandios is differently colored (though the distribution of the color is somewhat similar), 
and has a short beak ; the pectorals are white and the flukes slate color ; D. obscurus, Gray, to 
which Peale's Phocceva australis and D'Orbigny's D. bivillatus have been referred by Cassin and 
Gray, belongs to an entirely different group. None of Peale's other species resemble this one at 
all, and after long and careful consideration, I am forced to the conclusion that the species is 
undescribed ; and it is with great pleasure that I have followed the request of Captain Scammon, 
and dedicated it to Professor S. F. Baird, of the Smithsonian Institution, to whose never-tiring 
courtesy and unfailing liberality nearly every American naturalist is more or less indebted.
