is obtusely pointed. The orbit is conspicuously larger than in G. 

 argentatus or C. quincunciatus ; its length is contained 3.9 (3.85 

 to 4.15) times in the head, 1.8 (1.8 to 1.95) times in the snout, 

 1.15 (1.05 to 1.2) ,times in the postorbital. The least interorbital 

 width is greater than in the other species of the subgenus, it is a 

 little less than the orbital length, and is contained 1.3 (1.23 to 1.4) 

 times in the postorbital. The suborbital also averages wider, being 

 contained 2.6 (2.5 to 3.0) times in the postorbital. The short upper 

 jaw extends backward from below the posterior nostril not so far 

 as the vertical from hind margin of the orbit ; its length is contained 

 4.05 (4.2 to 4.35) times in the head. The barbel is short, being 

 contained 4.4 (3.4 to 4.6) times in the postorbital. The cardiform 

 teeth of the premaxillary are in a narrow band; those of the lower

jaw, in two irregular series on the sides posteriorly, become so 

 crowded near the symphysis as to form a narrow band. 



The anus is located immediately in advance of the origin of the 

 anal fin, somewhat farther forward than in C. quincunciatus, and 

 much farther forward than in argentatus; it lies below the posterior 

 half of the interdorsal space; the distance from the center of the 

 anus to the base of the outer ventral ray is contained 2.7 (2.9 to 3.5) 

 times in the head; the distance between the ventral fin and the 

 isthmus (at the front of the scaled area), is contained 3.3 (3.6 to 3.85) 

 times in the head; the total distance, from the anus to the isthmus, 

 1.6 (1.65 to 2.0) times. As in argentatus and quincunciatus, the 

 anterior lobe of the gland-like body in the abdominal wall is sup- 

 ported by a slender rod connected with the joined ends of the two 

 pairs of arms of the pubic bones. 



Pyloric caeca — 14 in 2 specimens (stations 5110 and 5118) ; 22 in 2 

 specimens (station 5518) ; 9 were counted in a specimen of argen- 

 tatus, and 8 to 11 were counted in 4 specimens of quincunciatus.
