than the lateral ones; the spinules increase in strength and height 

 posteriorly and are imbricate upon one another; the last one scarcely 

 projects beyond the margin of the scale. The terminal rostral plates 

 do not project strongly; they are rather bluntly pointed, and the 

 series of spinules (6 dorsal, 4 ventral), by which they are armed, 

 are extended forward to their tips; the length of the dorsoterminal 

 plate is contained 4.6 times in the postorbital length of head; the 

 plates are bounded on each side by an elongate scale, the first of the 

 eight covering the ethmoid region of the infraorbital ridge on each 

 side ; these scales of the ethmoid region increase in size posteriorly, 

 and bear 6 or fewer strong carinae directed upward and backward ; 

 9 scales, similarly armed, follow on the preorbital portion of the 

 ridge, which then becomes covered bv a double series of scales on the

suborbital and preopercular portions, behind the vertical from the 

 middle of eye. 



The median superior rostral ridge is covered by 10 shield-shaped 

 scales bearing at most 8 spinous ridges diverging backward and out- 

 ward from the front of each ; this median series is bounded on each 

 side by a single row of well-armed scales; a series of smaller scales 

 bounds the supranarial ridge scales, but the entire remaining antero- 

 lateral region of the snout is completely covered by small, crowded 

 scales, like those covering the lower half of the nasal fossa and the 

 region below the orbit extending backward to the preopercular ridge. 

 The anterior half of the area between the occipital ridges is covered 

 by five series of scales which decrease in size posteriorly and con- 

 verge toward the median occipital scute, which, like the smaller 

 scute preceding it on each side, is armed by a strong median keel. 

 The supranarial and antorbital ridges, and the anterior half of the 

 supraorbital ridge, are covered by scales bearing several divergent 

 spinous crests; the occipital, posterior half of supraorbital, and
