remains of the anterior end of the paraspheooid (jx/s.) 
exhibit the sockets for the characteristic tritoral teeth ; 
the vomer {v.) anteriorly hears a small transversely ex¬ 
tended patch of comparatively minute teeth, of which 
only the bases for attachment are preserved. In front, 
the vomer joins the ethmoid (eth.) in a dentate suture.
