Oligolepis jaarmani (Weber 1913)

Occurs near the river mouth.

Oxyurichthys jaarmani Weber, 1913

USNM 217266, Fly 75–28, 2: 30.1–32.6 mm.

USNM 217267, Fly 75–30, 8: 17.5–32.0 mm.

Stenogobius cf. genivittatus (Cuvier and Valenciennes, 1837)

USNM 217269, Fly 75–27, 26: 18.3–36.8 mm.

USNM 217270, Fly 75–28, 115: 15.3–54.2 mm.

Two lots of Stenogobius Bleeker, 1874 (type-species Gobius gymnopomus Bleeker, 1853, by original designation), from the Lower Fly are referable to S. genivittatus as understood by Koumans (1953:35–37). All of the larger specimens from Fly 75–28, including many as small or smaller than the largest specimens from Fly 75–27, have a relatively well-developed color pattern, with a large vertical (not oblique) bar on cheek below middle of eye, a small oblong vertical mark on dorsal one-third or one-half of pectoral fin base, and 8–9 thin, dusky vertical bars on the side of the body. Specimens from Fly 75–27 have a more terete head and slightly smaller eyes, but their coloration, albeit faint, appears basically identical to that of specimens from Fly 75–28. Fly 75–27 was taken from a shallow backwater of the Fly mainstream with a soft, muddy bottom, continuously roiled by wind and wave action and hence excessively turbid; Fly 75–28 was from a well-drained tidal creek with relatively compact bottom and much less turbid. I tentatively consider the two lots conspecific. On the other hand, I suspect that one or more of the five nominal species placed in the synonymy of S. genivittatus by Koumans are valid species.
