| Abstract |
We described the external features of an echinoid, Caenopedina pulchella (A. Agassiz & H. L. Clark, 1907), a rarely encountered species as well as the first record from Japanese waters. The morphological characteristics of three specimens collected off Nagasaki in the East China Sea (depth 384–378 m) in 2012, off Misaki in Sagami Bay (depth 94–100 m) in 2014, and off Toshima in the Izu Islands (depth 370 m) in 2015 were consistent with the previous descriptions. These findings expand the northernmost range of this species in the North Pacific. We proposed a new Japanese standard name, Myoga-gaze, for this species. |
