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 by 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
