Skeleton. — The upper surface of the skull is concave throughout ; 

 there is no ridge nor any other prominence between the elevated 

 orbital edges of the frontals ; from these fidges a sharp crest on each 

 side runs backwards to the articulation of the suprascapula ; the 

 occipital crest emits a median branch in front, which does not ex- 

 tend to the frontal. The maxillary bone is styliform in more than 

 its anterior half, suddenly widening behind, the superior and inferior 

 margins being rather irregularly curved. The prseoperculum is 

 rounded throughout, finely serrated behind, and exhibits four- or six 

 coarser denticulations at the angle ; operculum with three con- 

 spiciious spines, the upper of which is the most distant, and not 

 projecting beyond the margin ; the middle one is acute, longest and 

 strongest ; the lower rounded, short, but prominent, ^here are two 

 strong canines in the ujiper jaw, causing an impression in the lower 

 jaw, and receiving two smaller canines of the raandibula between;
