CHACEON QUINQUEDENS ( SMITH, 1879)

Type locality: Gulf of Mexico; Albatross collections ( Pequegnat, 1970) .

Known range: western Atlantic from Nova Scotia to Brazil and throughout the Gulf of Mexico with the exception of the south-western quadrant, from 366 to 1463 m (200–800 fathoms) ( Pequegnat, 1970).

Occurrence at vents or seeps: methane seeps off Louisiana.

Material: No material is known from the methane seep site where the species was reported ( Carney, 1994; MacAvoy et al., 2002).

Remarks: This species, originally described as Geryon quinquedens , was transferred to the genus Chaceon by Manning & Holthuis (1989). It was reported by Carney (1994) and MacAvoy et al. (2002) from methane seeps off Louisiana in the Gulf of Mexico. Pequegnat (1970) noted that this species (as Geryon quinquedens ) was one of only three brachyurans in the Gulf of Mexico that live in excess of 500 fathoms (914 m).
