Calocarcinus habei Takeda, 1980 . Stn 32, Nuku Hiva, 363 m (Fig. 8 a–b), on Madrepora sp. ( Scleractinia, Oculinidae) (specimen collected LC394).

Quadrella aff. coronata Dana, 1852 . Stn 16, Fatu Hiva, 315–340 m (Fig. 8 c–d), on Madracis sp. ( Scleractinia, Pocilloporidae) (specimens 2 spp. were collected LC 169, LC281).

Remarks. If our identification of Quadrella aff. coronata is confirmed when specimens collected are available for examination, it will represent a significant geographic extension for this species. This coral associated crab is widespread in the Indian Ocean, the Philippines, Papua New Guinea, and Vanuatu, from 2–26 m to 189–194 m (see Galil 1986; Castro 1999, 2009), and was recently reported at 442–491 m off Madagascar (Castro, in press: MIRIKY Expedition, Madagascar, stn CP3210, 29.6.2009, 12°44'S, 48°12'E, 442–491 m).
