_Barnegat City_ (female).—The first four cervicals are united. The
foramen above the anterior articular facets of the atlas is complete, and
the edges of these facets are raised. The inferior lateral process is
flat, broad, and strongly bent backward.
Second cervical: Inferior lateral process nearly as long as that of the
first cervical; broad, flat, and bent backward parallel with the process
of the first cervical. Superior lateral process short, strong, and flat.
A large incomplete foramen between it and the inferior process.
Third cervical: A short, conical inferior process, curved forward.
Fourth cervical: Similar, but with smaller and shorter inferior process.
Neural arch and spine complete; the latter fused with the preceding
spines. Arch not reducing the size of the neural canal.
Fifth cervical: Arch and spine broken. Arch nearly as broad as the
anterior epiphysis of the centrum. Inferior lateral process short,
straight, and directed obliquely outward.
Sixth cervical: Spine broken. Arch complete, nearly as wide as the
anterior epiphysis. Inferior lateral process short, thick, knobbed, and
directed obliquely outward and a very little forward. The left longer.
Seventh cervical: Spine obsolete. Arch complete, as wide as the anterior
epiphysis. No superior lateral process or metapophysis. A thick articular
facet for the head of the first rib on the middle of the side of the
centrum. No inferior lateral process.
Fused spines of the first to fourth cervicals bent backward; the mass
broad antero-posteriorly and rounded at the tip.
_Newport_ (male).—First cervical with the foramen over the anterior
articular facets incomplete, and the borders of the facets less raised.
The facets also broader and more declined. Inferior lateral process
thicker, somewhat tapering, and nearly transverse.
Second cervical: Inferior lateral process much shorter than that of first
cervical, about parallel with it, but with the tip bent forward. Superior
lateral process short, thick, and bent backward; joined to the inferior
process on the right side, inclosing an oval foramen.
Third cervical: A short, straight, triangular superior process on the
right side; that on the left short and blunt. Inferior lateral process
long, thick, club-shaped, and curved backward.
Fourth cervical: Inferior lateral process similar to the last in shape,
but shorter, broad and flat, and only slightly curved backward. Neural
arch and spine separate from those of the third cervical; the arch rather
smaller than those preceding it, and reducing the size of the neural
canal.
Fused spines of the first to third cervicals nearly vertical, rather
high, and obtusely pointed.
Fifth cervical: Spine pointed and quite long. Arch complete. Inferior
lateral process short, squared, flattened, and directed outward
obliquely.
Sixth cervical: Spine about as long as on the fifth cervical. Arch much
narrower than the anterior epiphysis. Inferior lateral process prominent,
thick, somewhat compressed, and directed downward.
Seventh cervical: Spine as high as the arch, obtusely pointed. Arch
complete, as wide as the anterior epiphysis. A strong conical superior
lateral process, or metapophysis, on a broad base, directed forward. An
articular raised facet on the side of the centrum, directed obliquely
backward. No inferior lateral process.
_Charleston_ (female, jr.).—The first to fourth cervicals resemble those
of the Newport skeleton, but the fourth entirely separate. All the
lateral processes undeveloped, or broken off, except the right inferior
lateral process of the atlas, which is like that of the Newport specimen.
The anterior foramen of the atlas is incomplete, as in that specimen, and
the spines of the conjoined vertebræ are vertical and pointed. (Pl. 25,
fig. 1.)
Fifth cervical: Spine wanting. Arch complete. Inferior lateral process
undeveloped, or abraded.
Sixth cervical: Spine and processes broken. Arch wide.
Seventh cervical: Similar to that of the Newport skeleton, but the spine
obsolete or broken.
