This beautiful white species is very characterized by the ornamentation of about 17 prominent ribs along the growth lines on the peripheral area and 24 rather weak ribs on the area between the fasciole and the suture on the body whorl. Ribs on the peripheral area are diminishing to both the base and the fasciole. The slit is narrow but rather deep. The umbilicus is wide and deeply perforated.Height 0.8 mm., the largest diameter 2.2 mm. and smallest diameter 1.7 mm.
Locality: Naze, Amami-Oshima far south of Kyushu.
Remarks: This locality is far from Tahiti, which is the type locality, but this shell is quite agreeable with the specimen from the type locality. Another specimen collected from Samboanga, Mindanao, the Philippines by Mr. Ichiro Yamamura, seems to be identical with the Japanese Scissurella straminea (A. Adams), which is a new locality.
