First northwestern Pacific records of the deep-sea cardinalfish Epigonus glossodontus (Teleostei, Epigonidae) from the Daito Islands, Japan
The deep-sea cardinalfish Epigonus glossodontus Gon, 1985, previously known only from the Hawaiian Islands, was observed on steep seafloors surrounding Kitadaito and Minamidaito islands, both being oceanic islands belonging to the Daito Islands, Japan in the northwestern Pacific. Sparse populations were mainly observed at depths of 340–588 m, around or within small caves, fissures, and recesses. A glossy bluish-green body color with black-margined scales was revealed by the field observations, the glossy color fading immediately after death. Its Japanese name is "ホラアナヒスイヤセムツ"(Horaanahisui-yasemutsu, meaning "cave jade deep-sea cardinalfish").

A New Species of Flabelligena (Annelida: Acrocirridae) from the Western Pacific
We discovered a new species of polychaete worm, Flabelligena daitoensis, belonging to the family Acrocirridae. This species is the first to be described from the Pacific Ocean. This species inhabits sandy environments at depths of 644 to 774 meters. The polychaete genus Flabelligena has previously been described from the Atlantic, Mediterranean, Indian, and Antarctic oceans.
The specific name daitoensis is derived from the fact that this species was first discovered near Minamidaito Island. Its Japanese name is "ダイトウヒメクマノアシツキ" (Daito-hime-kumanoashitsuki).
