Styela squamosa Herdman 1881 , p 66. Sanamyan, Sanamyan, 2006: 321 (synonymy).

Material examined. St. B5-11, 2651m, 6 specimens; St. B5-10, 2676m, 1 specimen; St. D2-8, 2653– 2683m, 1 specimen.

Remarks. Oval, dark brown or almost black specimens are up to 2cm in greatest diameter. Thick short rhizoids are on the proximal end. The tunic is firm, warty, often covered by bryozoans and hydroids. External appearance and internal features correspond well to previous descriptions.

There are several records of this species from North Pacific, although the species has not been known from the Sea of Japan until the present record.
