ABSTRACT Sampling for infaunal and epifaunal decapods on the continental shelf of the Gulf of Mexico has yielded rather extensive collections of goneplacid crabs which include a number of undescribed or poorly known species. We describe two new species, one assignable to Chasmocarcinus Rathbun, 1898, and another assignable to Speocarcinus Stimpson, 1859. Chasmocarcinus chacei is described for specimens taken at depths from 86-210 m in the southeastern, northeastern, northwestern, and southwestern Gulf. Records of this species include RV Alaminos collections formerly confused with C. cylindricus Rathbun, 1901. To distinguish C. chacei, we compare it to other members of the genus and thoroughly redescribe C. mississippiensis Rathbun, 1931, a poorly known Gulf endemic species that occurs at depths from 10-100 m. Speocarcinus monotuberculatus is described for a rarely occurring species known only from near 80 m on two hard-bank localities in the northwestern Gulf. To distinguish this species on the basis of present sexually immature materials and place it in the genus Speocarcinus, we compare it to S. carolinensis Stimpson, 1859, and to thoroughly redescribed materials of S. lobatus Guinot, 1969, a poorly known Gulf endemic species common in our collections at depths from 6-65 m. Species of both these genera, while not of close taxonomic relationship, are probably burrow-dwelling infaunal forms, and substrate as well as depth appears to influence their distributions on the shelf of the Gulf of Mexico.
