Lateral view of the Green Sunfish (Lepomis cyanellus), 157 mm total length (128 mm standard length), collected from the Nith River on 10 June 1976. cyanellus were collected at two locations. One locality was at a washed-out dam just north of Plattsville in Oxford County. On 10 June 1976, eight specimens were collected; on 30 September 1976, 14 individuals were collected. Both collections were from a deep (over m maximum depth) oxbow with only a limited connection with the river at the time of collecting. The bottom was muddy. Specimens from the 10 June collection ranged in size from mm to 157 mm total length ( mm to 128 mm standard length). Specimens from the Sep- tember collection ranged in total length from mm to 90 mm (26 mm to 73 mm standard length). The second location where specimens were col- lected was at Mornington Centennial Park, just north of Millbank, Perth County, on 25 March 1976. Four fingerlings were caught. The specimens were collected over a flood plain during a period of high water. The fingerlings ranged in size from mm to mm total length ( mm to 29 mm standard length). Adult L. cyanellus can be separated from other species of Lepomis by the large mouth, large eyes, and relatively short rounded pectoral fins (Figure 1). A dark spot is usually present at the base of the last rays of the dorsal fin, a character it shares with L. macrochirus, the bluegill. Specimens up to about 30 mm in total length, when alive, have a lateral coloration consisting of vertical rows of darkened spots enclosed within a vertically elongated light blue halo. This color pattern largely disappears when a specimen is placed in preservative. Slightly larger specimens do not exhibit the banded coloration of smaller individuals. No other specimen of Lepomis was collected in the Nith River. Lepomis gibbosus, the Pumpkinseed, however, has been recorded from Horner's Creek (= Whiteman's C
