Crabs of the Gulf of Mexico 101<br />

of the United States, whereas A^. texana occurs only along the Gulf coast. Reports<br />

of A^. texana in southern Florida (Tabb and Manning, 1961) are attributed by<br />

Abele to A^. packardii. Williams (1965) listed this species from North Carolina,<br />

but Abele (1972a) states that the figures are of A^. sayi. Florida listings include<br />

Wass (1955), Dragovich and Kelly (1964), Abele (1970), Lyons et al. (1971),<br />

and Menzel (1971). Other listings (some as A', texana sayi (= A', sayi), but all<br />

are referred to A^. texana) include the northwestern Gulf (Fotheringham and<br />

Brunenmeister, 1975) and Texas (Simmons, 1957; Parker, 1959; Hoese, 1960;<br />

Breuer, 1962; Hoese and Jones, 1963; Keith and Hulings, 1965; Leary, 1967).<br />

McMahan (1967) described lan^ae reared in the laboratory. Landers (1954)<br />

noted predation by this species on clams. Ryan (1956) gave accounts of life<br />

history for A^. sayi, which should be very similar to that of N. texana.<br />

and among fouling organisms; from bays and near-marine waters; on mangrove<br />

roots; from sand bottoms.<br />

Remarks: Felder (1973a) listed this species from Texas on the basis of a tentative<br />

identification. Garth (1961) noted the variability of this species over its<br />

entire geographical range and pointed to the possibility of future segregation of<br />

this species into distinct Pacific and Atlantic forms.<br />
