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, 1 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 0. gladius) . These terminal plates are bounded on each side 

 by a narrow scale, followed on the ethmoid region of the infraorbi- 

 tal ridge hj si^ 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 flapj less 

 prominent than in any other species of either Paramacrwrus or Oxy- 

 macruims 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 G. 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.
