PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 505 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 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.

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
