losis of the neural arches. The second cervical vertebra (figs. 1, 2) 
has large, broad, truncated lateral processes with a large, oblong, 
subcentral perforation ; the lateral processes are each two-thirds of 
the transverse diameter of the articulating surface of the body of the 
vertebra. The neural canal of the second cervical vertebra subcir- 
cular, rather less high than broad, and not quite so wide as half the 
diameter of the front sides of the body of it. The third cervical 
vertebra (see figs. 1, 2) has a thin, oblong, transverse body, which is 
broader than high; the lateral processes are slender, truncated at 
the end, not so long as the transverse diameter of the body, curved 
towards each other at the end, but not united so as to form a ring. 
The neural canal of the third cervical vertebra is oblong, transverse, 
rounded above, as wide as half the transverse diameter of the body 
of the vertebra, and about one-third broader than high. The rest 
of the cervical vertebre are free, not anchylosed either by the bodies 
or neural arches. The fifth or sixth cervical (see figs. 3, 4) has a 
thin body, with slender, nearly straight upper lateral processes, and
