specimens than in adults. Thus in small examples the pectoral fin nearly or quite 

 reaches the vertical from the origin of the spinous dorsal, but in large ones it 

 extends only § of the distance from its base to the spinous dorsal. 



In young examples also the adipose eyelid is thinner and more transparent, the 

 teeth are more evident, and the mandibulary angle is more acute than in the adults. 

 Poey's description of Mugll gnimardianus (Ann. Lye. N. York, xi. 1876, p. 64, t. 8. 

 figs. 1-3) was based on an example 225 mm. in length which was compared with one 

 of M. curema of 325 mm. The supposed specific differences are mostly very trivial 

 and due to individual variation (e. g., M. gainiardianus was said to have the body less 

 deep, the depth 5|^ iu the length as compared with 5 in M. curema) ; other differences, 

 i. e. the shorter snout, stronger teeth, and shorter distance between tip of pectoral and 

 spinous dorsal in M. gaimarclianus, are due to the diiferent size of the specimens 

 compared. The characters assigned to M. setosus (Gilbert, Proc. U.S. Nat. Mus. 1891, 

 p. 549) are those of young specimens of J/, curema.
