PHILIPPINE MACROUROID FISHES—GILBERT AND HUBBS. 495 
Pyloric caeca 21 in two paratypes of medium size, 19 in the largest 
specimen. 
The scales are relatively large, being in 44 (to 5) rows from the 
origin of the second dorsal fin to, but excluding, the lateral line 
series, in 5$ series between the second dorsal and the end of the 
anterior curve of the lateral line, which is located behind the opercu- 
lar angle a distance two-thirds as long as the head; behind this point 
the number of scale rows dorsal to the lateral line again decreases. 
The scales of the body are armed with from 4 to 6 (3 to 7) strongly 
spinous carinae, the median one of which is strongest, being armed 
by about 4 spinules (6 in the largest specimen). 
Examined under the microscope, the structure of the scale is seen 
to be similar to that of other species in the genus. The small focus

is surronded by fine, close-set circuli, which soon give place to coarser 
circuli, which are evenly spaced to the margin of the scale on 
all fields; they are parallel with the scale margin on the lateral 
fields, but may terminate on the basal margin at an obtuse angle, in 
which case the basal field is divided by a line along which the circuli 
of each side meet at an acute angle; the circuli on the apical field 
are perpendicular to lines drawn midway between the carinae. The 
structure of the spinules is indicated in the figures above. Their 
anterior and lateral edges appear as ridges, while the surfaces between 
these ridges are concave. In certain rather definite areas on the tail 
of a large specimen there occur scales which differ in certain features 
from normal ones; they are notably thinner, bearing rows of spinules 
which are more numerous and subparallel instead of divergent; 
their striae (circuli) are absent except near their margins. These 
scales are evidently abnormal and in all probability have been re-
