teeth on the slightly raised upper edge of the orbit, four or five 

 minute serratures in its middle part, and three larger jagged teeth 

 at its posterior corner. The two low, roimded interocular ridges 

 are separated from each other by a narrow mesial furrow, and the 

 whole space between the eyes does not exceed two-thirds of the dia- 

 meter of the orbit. The ridge which flanks the top of the cranium 

 is a regular saw with five teeth. A low, thin, irregularly incised 

 edge crests the infraorbitar ridge. Small scales cover the top of 

 the head to the nostrils. (Rich.)

Head •with, very low, thin, and serrated crests. A low double 

 crest skirts the upper edge of the orbit, and is followed on each side 

 of the crown by a rather higher single one. The second infraorbital, 

 which crosses the cheek, shows two thin, finely serrated crests, that 

 include a rugose disk. The proeopcrcular margin is serrated through- 

 out ; a very minute spine at its angle, and clusters of spinous points 

 on the usual sites of the four angular corners (?). Each hmb of the 

 lower jaw is traversed by three serrated crests. The operculum ends 

 in a minute spinous point. The interorbitar space exceeds half the 

 diameter of the orbit in breadth, and is scaly between the ridges. 

 Palatine bones toothless. (Rich.)

Palatine teeth none. The height of the body is one-fourth of the 

 total length, the length of the head one-third ; cheeks and operculum 

 entirely scaly. The diameter of the eye is 3 to 3| in tlie length of 

 the head, and the distance between the eyes ecjuals one-half their 

 diameter. No groove below the eye. Praiorbital with the spines 

 obtuse ; prominent spines on the crown of the head ; no skinny ap-
