Family Oregoniidae Garth, 1958

Confined to the northern hemisphere, oregoniids inhabit cold temperate, boreal and deep-sea environments. Barry et al. (1996: 1746) reported Chionoecetes bairdi Rathbun, 1924 from the Monterey Submarine Canyon. This species has not been reported previously from anywhere south of Washington. If this identification is correct, this record constitutes a significant southern range extension for the species. Garth (1958: pl. 15) and Jensen (1995: fig. 11) illustrated this species.
