94 Lawrence W. Powers<br />
Depth: near shore subtidal to 139 m (to 76 fm).<br />
Habitat: most commonly on muddy bottoms; occasionally on sand, shell, and<br />
gravel substrates; on oyster beds.<br />
Remarks: Developmental studies include data on growth conditions for zoeal<br />
stages (Chamberlain, 1961), descriptions of larval stages as reared in the laboratory<br />
(Costlow and Bookhout, 1966a), and notes on larval ecology in Chesapeake<br />
Bight (Sandifer, 1973). Williams (1965) summarized records of ovigerous<br />
females. Ryan (1956) described the general life history of this crab in Chesapeake<br />
Bay. Hazlett (1976) studied agonistic behaviors. Regional lists include<br />
Florida (Wass, 1955; Dragovich and Kelly, 1964; Abele, 1970; Menzel, 1971;<br />
L3'ons et al, 1971), Louisiana (Behre, 1950), and Texas (Hedgpeth, 1953;<br />
Leary, 1967).<br />

Habitat: sand bottoms; coral banks.<br />
Remarks: Menzies (1948) noted that this species did not fit the generic description<br />
of Lophopanopeus and he transferred it to Hexapanopeus, the American<br />
genus it most closely resembled.<br />
