Crabs of the Gulf of Mexico 31<br />
Remarks: The breeding range for this crab extends only to North Carolina,<br />
but larvae as far north as New England may occasionally survive a mild winter<br />
to provide temporary range extensions (Hay and Shore, 1918; Holthuis, 1958).<br />
Some of the larval stages are figured by Lebour (1944). This species was revised<br />
by Holthuis (1958), who found at least two species that had been previously<br />
combined under this name. One of these, C. ocellata, also occurs in the Gulf of<br />
Mexico, thus previous records, particularly from off west Florida, may refer to<br />
either or both species. Listed from the R/V Oregon collections in the Gulf bj^<br />
Chace (1956). Cheliped modifications associated with shell opening of molluscs<br />
were described bjr Shoup (1968).<br />

lor the African and Asian areas, respectivelj^ Coelho and Ramos (1972) and<br />

Remarks: Plates 59 and 60 of Rathbun (1937) are of C. flammea, not C.<br />
ocellata. Other records of C. flammea may also include specimens of this species,<br />
especially reports prior to the revision bj^ Holthuis (1958). Shoup (1968) described<br />
shell opening behavior by this species and other Calappa. Coelho and<br />
Ramos (1972) list this crab from Brazil.
