In addition to the color marks described by Radcliffe, a dark streak 
extends along the anterior half of the tail immediately above the 
lateral line. The opercle is dusky, and a dark streak lies just below 
the postorbital ridge. 
Scales in 5 series from origin of second dorsal fin to, but excluding, 
the lateral line scales; in 6 series behind anterior curve of lateral line. 
The 5 to 7 series of short, robust, suberect spinules on the scales of 
the body, moderately divergent posteriorly, become strongly di- 
vergent toward the head. The scales of the head, much as in the 
species of the subgenus Quincuncia, bear numerous suberect spinules 
arranged usually in quincunx order,’ but sometimes in divergent or 
stellate series. The sharply acuminate tip of the snout is covered by 
a spinigerous plate above and below; the length of the dorsoterminal 
plate is about two-thirds that of the orbit (the two measurements are 
equal in C. gladius). These terminal plates are bounded on each side 
by a narrow scale, followed on the ethmoid region of the infraorbi- 
tal ridge by six scales; the suborbital and preopercular regions of the 
ridge are covered more or less irregularly by two series of scales; 
the ridge ends sharply just before the margin of the produced pre- 
opercular lobe. The subopercle is produced backward, behind the 
upper margin of preopercular lobe, into a very obtuse, short flap, less 
prominent than in any other species of either Paramacrurus or Oxy- 
macrurus examined. A long, narrow, scaleless groove, more promi- 
nent than in C. gladius, bounds along its entire length that series of 
scales on each side of the series on the median rostral ridge; a few 
scales (many in (@. gladius) lie between this groove and the scales 
of the infraorbital ridge. The occipital ridges diverge toward their 
posterior ends, where they are separated by a distance one-third 
greater than the least distance between the ridges, a distance con- 
tained 1.7 to 1.9 times in the least interorbital width. From the 
many-spined median occipital scute there extends outward and for- 
ward a scaly ridge which meets the occipital ridge on each side above 
the hind margin of the orbit; this ridge is preceded on each side by 
series of strengthened scales; similar scales also cover the triangular 
area included between this short ridge and the occipital ridge on 
each side; another scaly ridge, formed over the supraoccipital crest.
