Page The presence of one or two anal spines in Gymscion has 
no importance. I’robably a rudiment of the lirst spine will be found 
in all the species. Gynoscion regale and Gyiioseion notimm are distin- 
guished from our other species by having the second dorsal and anal 
covered with small scales; these tins being naked in the other species. 
OtoUfhus drummondi liich. (Fauna Bor.-Amer. iii, 183(1, 70; Gunther, ii, 
.307), from New Orleans, is identical with Gipioscion )nacukitum. This 
species has the caudal unevenly truncate, not “lunate”, as stated in the 
text.

Color silvery olivaceous ; scales with faint silvery streaks but no dark 
ones; tins mostly pale or yellowish, the ventrals somewhat dusky. 
Body rhomboid, short and deep, the back elevated, the anterior protile 
straight and very steej) ; mouth rather large; teeth slender, brush-like. 
Preorbital entire ; preopercle and interopercle serrate. Groove on top 
of head, for reception of ijremaxillaries, broad, rounded behind, with a

deciduous scales, which extend forward to just behind nostrils. Eye

as long as head. Second anal spine very strong, half or more length of 
head. Caudal lobes long and slender, a little longer than head. Pec- 
toral long, nearly as long as head, reaching front of anal. Head 3;

This species is distinguished from the other American species (ex- 
cept Gerres liomonymus) by the presence of a transverse baud of scales 
across the anterior jtart of the groove of the itremaxillaries on the top 
of the head; behind these scales the naked part of the groove appears 
;is a pit when the jaw is prorruded. Third dorsal spine as long as 
liead, twice as long as second anal spine. Head 3|; depth 2f. D. 
IX, 10; A. HI, 7; scales 4-45-0. Tip of dorsal dusky. West Indies, 
north to Cape Cod.
