ec. Front teeth incisor-like; no canines. 
e. Incisors broad; molars in 2 to 4 series in each jaw. 
/. ¥irst spine-bearing interneural with an antrorse spine in front, 
g. Supraoccipital and temporal crests nowhere coalescent, the inter- 
orbital area not swollen; frontal bone in the interorbital area thin, 
concave in transverse section; temporal crest low, separated from 
supraoccipital crest by a flattish area which extends forward on each 
side of supraoccipital crest and to groove of premaxillary spines. 
(Incisors conspicuously notched.)-------..--.---.-=..- LAGODON, 26. 
gg. Supraoecipital and temporal crests coalescent anteriorly, both dis- 
appearing in the gibbous interorbital area; frontal bone between 
eyes transversely convex and more or less honeycombed; temporal 
crest separated from occipital crest by an excavated area, bounded 
anteriorly by the lateral crest, which merges into the supraoccipital 
above eye. (Incisors entire or with a shallow notch.) 
ARCHOSARGUS, 27. 
ff. First spine-bearing interneural without antrorse spine above; skull
