926 FISHES—CENTRARCHIDA, 
Storer, and after him Kirtland and others, have confounded this fish 
with P. annularis. The synonym carolinensis, Gill, was given on the pre- 
sumption that the Carolina fish was specifically different from that in- 
habiting the Great Lakes, which, however, does not seem to ba the case. 
Both this species and the preceding have been recommended for the 
stocking of ponds.

Centrarchus, AGAssiz, American Journal Sci. Arts, 1854. 
Eucentrarchus, GILL, Amer. Journ. Sci. Arts, 1264, 92 (irideus, name only). 
Type, Labrus irideus, Lacepede. | 
Etymology, kentron, spine; archos, anus, from the many anal spines. 
Dorsal and anal fins about equal in extent, the soft portion of the latter longest and 
most posterior, the two fins being obliquely opposed ; spinous dorsal longer than soft 
part forming angle with it, the spines normally about 12 in number, not rapidly 
graduated ; anal spines normally 8; body deep, compressed ; mouth moderate; lower 
jaw longest; supplemental maxillary bone well developed; teeth on palatines; gill 
rakers setiform, very long, in large number (25 to 30) on anterior gill arch, armed with 
small teeth; scales nearly smooth; opercle emarginate, ending in two flat points; 
caudal fin emarginated. But one species of this genus is now known. 
Synonymy.—The name Centrarchts was first proposed for Ambloplites rupestris, Cen- 
trarchus irideus, and Pomoxys spareices under the names of C. @neus (LeSuenz), C. pen- 
tacanthus (C. & V.), C. irideus (Lac.), and C. sparoides (Lac,). No type was assigned. 
‘Afterwards (i832) species of Pomoxys (hexacanthus) and of Chenobrytius (gulosus and 
viridis) were .dded by Cuvier and Valenciennes. Later (1242) DeKay added two nom- 
inal species of Microplerus ( fasciatus and obscurus). In 1854, Prof. Agassiz revived the 
Rafinesquian genera, Ambloplites, Pomoxis, and Calliurus for species then referred to 
Centrarchus, properly retaining the name Centrarchus for the species belonging to the 
original genus which had not previously been made types of other genera, 3. e., VU. irideus. 
In 1864, Prof. Gill suggested the name Lucentrarchus for Centrarchus irideus to be used 
in case of the general adoption of the rule requiring that the first species mentioned 
under a new genus should be considered its type, unless some other type was specified, 
The species first mentioned under Centrarchus was C. eneus, and under this view, Cen- 
trarchus would be a mere synonym of Ambloplites. The general common sense of natu- 
ralists has, however, rejected the ‘first species” rule as impracticable and undesir- 
able.
