St. WS 992, 100-0 m., 1 phyllosoma, ?stage VIII. Jasus lalandii is the common crawfish of the district. Phyllosoma, stage I, measured 1-5 mm. from the front to the end of the telson. It has been well described by Gilchrist (1916). A peculiarity of the phyllosomas of Jasus, unlike the other Palinuridae, is the absence of an exopod on the first maxillipede, except for a minute rudiment in some of the later stages. Gurney (1936) specially notes this as a character of all known phyllosomas of the Scyllaridae. The first stage of Jasus (which has been shown by Gilchrist to emerge from a naupliosoma) is very like some of the known first stages of Scyllarus.
