The nasals, the upper profile of which is a nearly straight, hori- 
zontal line, are quite strongly convex in the transverse direction and of

bluntly rounded tips, which project but little in front of the free border of 
the premaxillaries. Posteriorly, the nasals contract very gradually to a 
point above the second molar and thence broaden slightly to the frontal 
border ; the hinder ends, which are enclosed by the frontals, are wedge- 
shaped. The lachrymal appears to have no spine, but, as this bone 
is slightly injured on each side of the head, this is somewhat uncertain.
