Abstract / Introduction / Summary:

A pyramidellid mollusks of the genus Turbonilla was recorded from West off Koshiki island, Kyushu, in a depth of 140 m. This species resembles some known deep-sea species, such as T. pucicea Okutani, 1964 and T. corgani Okutani, 1968. The newly recorded species differs from these species in having two yellow color bands on their whorls. A dead shell of another species from Solomon Sea in a depth of 293 m was also examined and identified as Turbonilla danii Peñas & Rolán, 2010.
