_Barnegat City_ (female).—First lumbar: Similar to last thoracic, but
transverse process expanded distally and slightly directed forward; a
little longer than centrum; anterior and posterior edges emarginate
proximally.
Eleventh lumbar (last): Centrum very long. Neural arch and spine very
high, more than twice length of centrum. Spine inclined backward much
beyond posterior face of centrum; anterior margin straight, posterior
convex, tip expanded. Transverse process a little more than one-half
length of centrum, somewhat expanded at distal end and curved forward so
that tip is about in line with anterior face of centrum. Metapophyses
close to centrum and to each other, semihexagonal in outline. A sharp
median inferior ridge, and shallow posterior oblique channels on under
side of centrum.
_Newport_ (male).—First lumbar: Similar to that of Barnegat skeleton, but
transverse processes considerably longer than the centrum and not
expanded at tip; anterior edge straight, posterior only slightly
emarginate proximally.
Tenth lumbar (last): Centrum like that in Barnegat skeleton. Neural arch
and spine only slightly higher than length of centrum. Transverse process
oblong, free margin nearly transverse; process inclined forward so that
tip is a little beyond anterior face of centrum. Metapophyses close to
centrum, rounded in outline. Neural spine much inclined backward;
anterior edge concave, posterior convex, tip expanded. A rounded inferior
median ridge and very distinct oblique posterior channels on under side
of centrum.
_Charleston_ (female, jr.).—First lumbar: Similar to that of Barnegat
skeleton, but transverse process directed outward and scarcely or not at
all forward; length of process equal to that of centrum; tip rounded (due
to immaturity).
Tenth lumbar (last): Centrum very long. Neural arch and spine a little
less in height than length of centrum. Transverse process oblong, curved
forward, more than one-half as long as centrum. Metapophyses similar to
those of Newport skeleton. Inferior median ridge very sharp; lateral
channels rather indistinct.
