The ha3mal arch, fig. 81, 20-i2, H, is drawn forward, so that its apexi as well as its piers, are joined to the centrum (vomer), and usually also to the neural spine (nasal), closing up anteriorly the neural canal. The pleurapophyses are simple, short, sending backward an expanded plate ; they are called ' palatines,' ib. and fin-. 84, 20. The hasmapophyses are simple, and their essential part, intervening between the pleurapophysis and hajmal spine, is 81. side view &f cranial vcrtelirie ami senf-e-capsules ; tlie biumai arelic?, H n, in outline, Cotl (^[ui^rJlua i-uJiroris) short and thick ; Ijut they send a long ])rocess backward ; this element is called 'maxillary,' ib. 21. The haemal spine, cleft at the middle line, sends one process upward of varying length in different fislies, and a second downward and backward, and its under surface is beset with teeth in most fishes: it is called ' premaxillary,' ib. 22. Each pleura[)ophysis supports a ' diverg- ing appendage,' consisting commonly of two bones: the outer oue, which fixes the present hajmal arch to the succeeding one, is called 'pterygoid,' figs. 75, 81, 24; the inner one is the ' ento- pterj'goid,' ib. 23. The entire segment is called the ' nasal vertebra ;' its neural arch is the ' rliinencephalic;' its hremal arch, forming what is termed the upper jaw (), is called the ' maxillary' arcli and appendages. On reviewing the arrangement of the bones of the foregoing segments, one cannot but be struck l)y the strength of the arches which protect and encompass the brain, and by the efficiency of that.
