230 J. Wyman on Remains of Vertebrated Animals 
the penitentiary, Dr. Burton obtained several other portions of the 
skeleton of another seal. These consisted of an imperfect cervical 
vertebra, a lumbar vertebra nearly entire, a fragment of the sacrum, 
coccygeal vertebra, fragments of ribs and the lower extremity of a 
fibula. Their generic characters have been satisfactorily made out 
by comparisons with recent bones.* 
In figure 1, page 232, I have carota the coccygeal ver- 
tebra which corresponds in its general characters very accu- 
rately with recent bones of P. Groenlandica from the same 
region of the vertebral column. The small size of the vertebral 
canal and the imperfect transverse process, the wide spread ar- 
ticulating processes and the blunted spinous process indicate its 
affinity to the seals. 
The anes of a left fibula (figs. 2 and 3) presents at its lower 
extremit “(fig. 3), an oblique regularly patie artic nae 
surface, on its inner face, and on its outer (figs. 2 and 3,) an 
elevated ridge or crest on either side of which is a groove for the 
passing. of a tendon.
