bead; lewer jaw much shorter than upper; mouth horizontal, maxil- 
lary extending scarcely beyond middle of eye; teeth in upper jaw in 
a villiform band, the outer series somewhat enlarged ; gill-raker8 
about as long as pupil; longest dorsal spine little more than half length 
of head; second anal spine about 2 in bead, # the height of the soft 
rays; caudal fin long, double truncate, the middle rays produced; yven- 
trals reaching vent; color light reddish-brown, with dark punctula- 
tions; caudal yellow ; anal almost black ; lining of gill-cavity dusky ;

ALUTA, 46. 
gg. Dorsal rays X-I, 21 or 22; scales moderate, 50 to 55 in the lateral 
line; pectoral 14 in head; caudal 1#in head ; back somewhat elevated, 
the form of the body much as in Sciena sciera and related species; 
preorbital broader than in other species of Lairdiella, + width of eye; 
eye 5in head; snout bluntish 42; interorbital space 33; head thick, 
somewhat more cavernous than in related forms; premaxillary en- 
tirely below level of eye; maxillary 22? in head; teeth of outer series 
of upper jaw enlarged; lowest serree on preopercle smaller and less 
turned forward than in the other species; dorsal spines rather stout, 
‘ the second strong, the third longest, 1} in head; second anal spine 
shorter than the soft rays, 2}in head; the form and size of these spines 
very variable ; gill-rakers short and slender, X+ 15, the longest not as 
long as pupil; caudal fin double truncate; color soiled brassy, ir- 
regularly mottled, with large patches of sbining golden brown; faint 
dark stripes along the rows of scales above, those below lateral line 
nearly horizontal, those above oblique; head 3} in length; depth 3. 
D. X-I, 21 or 22; A. II, 9; scales, 6-50 to 55-13....CHRYSOLEUCA, 47. 
40. BAIRDIELLA ARCHIDIUM. 
Odontoscion archidium Jordan & Gilbert, Bull. U. S. Fish Com., 1881, 317 (Panama). 
Jordan & Gilbert, Bull. U.S. Fish Com., 1882, 111 (Panama). 
Habitat.—Pacific coast of tropical America, Panama. 
This species is not very common about Panama, where three speci- 
mens were taken by Dr. Gilbert. Although it bears a very strong re- 
semblance to Odentoscion dentex, it should, we think, rather be placed 
in Bairdiella than in Odontoscion. It has the very small anal of Odon- 
toscion and the spur-like preopercular spine of Bairdiella, while in its — 
dentition it is intermediate.
