Genus CENTRARCHUS, Cuvier. 
18, Centrarchus irideus (Lac.) C. & V. 
C. irideus, JORDAN, Bull. U. 8. Nat. Mus. No. 10, 31. 
At Narkeeta, on the Mobile and Ohio Railroad, I saw a specimen of 
Centrarchus taken from the Sucarnochee River, but was not able to pro- 
eure it. From an examination made at the time I regard it as being 
C. irideus. It appeared, however, to have some of the characters of 
C. macropterus ; there being, for instance, 8 anal spines instead of 7, the 
usual number.*

GENnus POMOXYS, Rafinesque. 
19. Pomoxys nigromaculatus (Le 8.) Girard. (No. 27,461.) 
Centrarchus hexacanthus, DEKay, Fauna N. Y. Fishes, vol. iv, 1842, 31. 
Pomozxis nigromaculatus, GIRARD, Pac. R. R. Sury. vol. x, 6. 
Numerous specimens of this were taken from Horsehunter Creek at 
Macon. Both this and the next are much sought after as food and to 
stock fish-ponds. 
20. Pomoxys annularis, Rafinesque. (No. 27,460.) 
Pomoxis annularis and nitidus, GIRARD, Pac. R. R. Surv. vol. x, 6. 
Same locality as above. 
Faminy ELASSOMATIDA. 
GENUS ELASSOMA, Jordan.

Nat. Hist. No. 2, 47. 
Two specimens of this interesting species were secured in a pond 
along the Noxubee River at Macon. The largest was 13 inches in 
length, somewhat larger than the specimens hitherto found. After care- 
ful search I have been unable to find any evidences of the existence of 
vomerine teeth in this species. The fin-formula is, D. 1; V,10; A. III, 5 
or 6. The scales are very small and difficult to count. As nearly as I 
could make out, there are 42 vertical rows and 18 or 20 horizontal rows 
between anal and dorsal. The pseudobranchiz are obsolete. 
* Since this paper has gone to press, Professor Jordan writes me that he is now sat- 
isfied that C. macropterus and C. irideus are identical, and that as the term macropterus 
has the priority, it must be accepted as the name of the species. He had already, in 
his ‘‘ Catalogue of the Fishes of Illinois,” published in Bull. No. 2, Hl. Lab. Nat. Hist., 
expressed the opinion that they might have to be merged into one.
