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 Mugil gaimardianus (Ann. Lyc. 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 UM. curema of 325 mm. The supposed specific differences are mostly very trivial 
and due to individual variation (e. g., M. gaimardianus was said to have the body less 
deep, the depth 5§ in the length as compared with 5 in M/. curema); other differences, 
z. e. the shorter snout, stronger teeth, and shorter distance between tip of pectoral and 
spinous dorsal in MM. gaimardianus, are due to the different size of the specimens 
compared. ‘The characters assigned to J. setosus (Gilbert, Proc. U.S. Nat. Mus. 1891, 
p. 549) are those of young specimens of M/. curema.

This genus differs from Mugil principally in having 2 anal spines instead of 3. It 
comprises “Grey Mullets” of small size, which have not been recorded as entering 
fresh waters.
