Stenothoe valida Dana

Stenothoe valida Dana.—Chilton, 1923:95–100, fig. 5 [in part, figures accepted, synonymy rejected].

Chilton synonymized many species with S. valida and his report of specimens of S. valida from Port Jackson may actually have concerned S. miersi, a distinct species (p. 120). His undocumented figures, however, show S. valida; they may have been taken from non-Australian specimens. The probability that S. valida occurs in Australia is high. The species apparently has been introduced from fouling matter carried on the hulls of ships into many ports of the world.

DISTRIBUTION.—?Port Jackson.
