I have met with striking instances of the rule in the case of varieties intermediate between well-marked varieties in the genus Balanus
. And it would appear from information given me by Mr.
Such effects have been observed in the gastropods Crepidula fornicata (Pechenik et al., 1996a, b, 2002; Pechenik and Tyrell, 2015) and Crepidula onyx (Chiu et al., 2007), the bivalve Mytilus galloprovincialis (Phillips, 2002, 2004), the polychaete Polydora ligni (Qian et al., 1990), and the barnacles Balanus
amphitrite (Thiyagarajan et al., 2003) and Austrominius modestus (Torres et al., 2016).
Using the [delta][.sup.15]N and [delta][.sup.13]C of big-claw snapping shrimps (Alpheus heterochaelis) and ivory barnacles (Balanus
eburneus) collected between 1850 and 2004, this study sought to detect incorporation of anthropogenic nitrogen before and after major changes in population or fertilizer use.
Geographic limits and local zonation: the barnacles Semibalanus (Balanus
) and Chthamalus in New England.
These ostreids are disarticulated and not in living position, showing the boring Gastrochaenolites, and remains of Balanus
. The upper 40 cm are rich in trace fossils Ophiomorpha, Gyrolithes and Skolithos, and bivalves (Aequipecten, Amusium, Cardium, Chlamys, Glycymeris and Pecten).

A widespread and conspicuous species in the north-eastern Baltic Sea that produces such structures is Balanus
(Amphibalanus) improvisus (Durr and Wahl, 2004; Kotta et al., 2006).
Thus, biochemical biomarkers evaluated in the barnacle Balanus
improvisus (Crustacea: Cirripedia) sampled from both polluted and reference sites in the Patos Lagoon Estuary, Southern Brazil showed pollution and seasonal effects .
