Gerres embryx JORDAN and STARKS, in Jordan and Evermann, Fish. North 
and Mid. Amer., II, 1898, p. 1879 (Charleston). 
Nineteen specimens from Tampico forming a graduated series, 
from 33 inches to 124 inches in length. 
These show plainly the identity of the nominal species of Gerres, 
plumiert, brasilianus, and embryx. Embryx was separated from 
brasilianus mainly because of the greater length of the pectorals, a 
character which does not hold good in this series. Plumieri, as de- 
scribed, differs from braszlianus chiefly in the greater length of the 
second dorsal spine (longer than head, instead of two-thirds to three- 
fourths of head), again an untrustworthy character as the following 
measurements prove. Plwmieri, as described, is the young of brasili- 
anus, that is, the dorsal and anal spines are proportionately longer in 
younger specimens. However, there are exceptions to the presence of 
long spines in the young, as occasionally a young example will show 
the measurements of the adult.
