the collecting was done in a small arm just above the bridge, with a bottom of mixed 
sand and mud. 
(e) The Satilla River at Waycross . — This is a moderately swift swamp- water stream, 
with a bottom of white sand. The depth was 8 to 10 feet in the channel; the width 50 
to 70 feet. Temperature 76° on July 2. The sand-bars were the only places that could 
be examined, and they yielded almost nothing. The Ashes were principally obtained 
in a small lagoon 3 to 5 feet deep. 
1. Noturus leptacauthus Jordan. 
One specimen obtained in the Ogeechee River. 
2. Ameiurus platycephalus (Girard). 
A. few obtained at Millen. A. 21 to 23. 
3. Ameiurus albidus (LeSueiir). 
Several specimens obtained at Savannah. I know of no characters distinguishing 
Southern specimens (niveiventris) from Northern {albidus, lophius) or from South- 
western (lupus), and unite them therefore under the oldest name. 
4. Erimyzon sucetta (Lacdpede.) 
Three specimens from the Ogeechee River, at Millen, have the scales in 36 to 38 
transverse series. 
5. Notropis roseus (Jordan.) 
This species, hitherto known only from a few specimens taken in the Tangipahoa 
(Notalbany) River in Louisiana, seems to be the most abundant minnow in the low- 
land streams of Georgia. It was obtained in every stream examined. Brier Creek, 
the Ogeechee River, and Satilla River, and was everywhere common. It much resem- 
bles W. chalyhceus, with which it is found associated, but may be distinguished at once 
by the broader head, blunter snout, and less oblique but somewhat larger mouth, the 
black lateral baud less intense, and not including the lower jaw ; the anal is quite 
constantly I, 7, instead of I, 8 as in chalybreus. The head is shorter than indicated 
in the original description, averaging 4^ in length, and the depth is somewhat greater. 
6. Notropis chalybaeus (Cope). 
Abundant in the Ogeechee River at Millen. 
7. Opsopoeodus emiliee Hay. 
Two specimens taken in a lagoon of the Ogeechee River at Millen. Agreeing with 
the original description in having the lat. 1. complete. All northern specimens ex- 
amined have it incomplete, and may belong to a distinct geographical variety {megalops 
Forbes). 
8. Opsopoeodus bollmani sp. nov. 
Differing from 0. emilke in the nearly horizontal mouth with lateral cleft, and in 
the conspicuous round black spot at base of caudal. 
Head small, snout compressed, slender, somewhat rounded at tip, resembling 
Hybopsis labrosus. Mouth small, subterminal, usually slightly overhung by the snout, 
the cleft slightly oblique ; maxillary reaching vertical from posterior nostril, shorter 
than snout, 4^ in head. Eye equaling snout, 3| in head, less than interorbital width. 
Pharyngeal teeth 5-5 or 4-5, with well-developed grinding surface, one edge of 
which is conspicuously serrated, though less strongly so than in emilice. The pharyn-
