120. DICENTRARCHUS PUNCTATUS. 
Scicena punctata Bloch, Ichthyologia, V, 64, 1793, taf. 305 (not Perea punctata L., which is Bodianus 
fulvus). 
Perea punctata Bloch &. Schneider, Syst. Ichth,. 1601, 91 (not of Linuteus, nor of Gmelin, who are quoted 
in synonymy) 
Labrax punctatas Gunther, Ann. Mag., Nat. Hist., 1863, 174 (Gibraltar); Brito Capello Jorn. Sci., 
Math.Phys. Lisboa, H, 154, 1867 (Lisbon) ; Steindachner, Ichthyol. Berichte, I, 1867, 5, (Porto, 
Lisbon, Cadiz, Malaga, Teneriffe) ; Steindachner, Fisch-fauna des Senegals, 1869, 3 (St. Louis, 
Senegal ; Gorea). 
Habitat. — Mediterranean Sea and adjacent waters. 
Etymology. — Punctatus, dotted. 
We have not studied this species and we draw our knowledge of it chiefly from the 
accounts of Giinther and Steindachner. Thesi)ecitic Wciiue punctatus may be retained 
in spite of the fact that the name Perea ptmetata had been earlier applied by Gmelin 
to Morone labrax. This use of the name, Perea punctata.! by Gmelin is evidently the 
result of a misprint. By some means the original description of Perea punctata h. has 
been left out, as also the name of the species next in order, Perea labrax L. By this 
means the name PercujiMitchita is left to stand over the description belonging to the 
other fish. 
Genus XXXIII.—PEECIGHTHYS.* 
Percichthys Girard, Proc. Ac. Nat. Sci., 1854, 197 (chileiisis). 
Percosoma Gill, Proc. Ac. Nat. Sci. Phila., 1861, 51 {melanops). 
Type. — Percichthys chilensis Girard. 
Etymology. — Perea perch); fish. 
This genus is composed of fresh-water fishes inhabiting the rivers of Chili. We 
have studied but one of the species, and are not quite certain of the relations of the 
genus. Its external characters are similar to those of the Latince., though the general 
form of the body is remarkably like that of Perea. The following analysis of the spe- 
cies is chiefly a compilation, and it will probably be found of little value. 
ANALYSIS OF SPECIES OF PERCICHTHYS. t 
a. Branchioategals seven ; caudal peduncle long and slender, its length nearly three times its least depth ; 
maxillary reaching to below middle of eye, 2f in head; snout moderately pointed, 3| in head ; 
second dorsal spine in head ; second anal spine scarcely equal to eye ; c(dor olivaceous brown, 
more or less spotted with darker: preorbital, suborbital, mandible, and preopercle cavernous.

*The distinction of the species of this genus has been questioned by Dr. Steindachner, who 
says : “In den Auden eutspriugenden Fliisse des siidlichen und mittleren Theiles von Chile und Pata- 
goiiieu mit mehreren ( wahrscheinlich nur zvvei) Arten der ZArca-ahnlichen Gattuug Percichthps und 
Percilia hevolkert siud.” (Ichth., Beitr., vii, 24.) Peters (Berl. Monatsber., I1566, 708) takes a very dif- 
ferent view. He says; “ Im Allgemeinen kann man wohl sagen dass Chile arm an Susswasserflscheu 
ist, indessen ist ihre Zahl doch weit betrachtlicher als man hisher geglauht hat. Im Work von Gay 
ist von Percoiden die einzige Perea trucha aufgefiihrt, welche Girard in der United States Naval Astro- 
nomical Expedition als Percilia chilensis genauer beschreibt und abbildet. Derselbe fiigt aus dieser 
Familie Percichthys melanops und Percichthys gillissii hinzu. Z wei audio Arten dieser Familie habe Ich 
als Perea pocha und P. segethi beschrieben, und kann jetzt noch eine zweite Art Percilia hiuzuftigen so 
dass mir jetzt anstatt einer Percoidee deren sechs aus den Fliissen Chiles bekanut sind, ich glaube aber, 
dass es noch mehrere Arten Percichthys gibt.” 
t We are unable to find the description of Perea pocha and Perea segethi Peters, species of this 
group described by Professor Peters from Chili.
