Tanystylum scrutator Stock, 1954b:142–145, fig. 70.—Utinomi, 1971a:337.—Nakamura and Child, 1983:41.—Kim and Hong, 1986:50.

MATERIAL EXAMINED.—HONSHU: Wakayama Prefecture, Goboh, 1.5 m, Feb 1981 (1 1); 3 m, Feb 1981 (1). Sagami Bay, Nabeta Bay, 7–15 m, 3 Jun 1972 (1). Off Kisami, 33–40 m, 4 Dec 1981 (1). Chiba Prefecture, Kominato, shallow, 23 Feb 1986 (2 with eggs, 2, 4 juv).

DISTRIBUTION.—Although this species is the most collected of the three species known to Japanese waters, the genus is relatively rare in Japan and is more typical of tropical shallow waters from which about 40 species have been described. This species was only known from Sagami Bay until recently when it was recorded from Korea (Kim and Hong, 1986:50), and herein from south of Sagami Bay in the shallows of Kii Strait. The greatest depth known for the species is 15 meters.

DISTRIBUTION.—This species is so far known only in Sagami Bay. The above specimens were taken across the Bay from the type locality at Nabeta Bay, but in much the same shallow depth.

MATERIAL EXAMINED.—HONSHU: Shirahama, Izu Peninsula, Spring 1984 (3 with eggs, 1); (4 with eggs, 1, 1). Omaezaki, Shizuoka Prefecture, 18 May 1984 (1 juv, probably this species). Sagami Bay, Shimoda Marine Research Center overflow drain, 15 Oct 1980 (1).

DISTRIBUTION.—This species was taken in American Samoa (type locality) and has been found along the Korean coast (as A. viridintestinalis) in several shallow localities. These above records are the first from Japan and establish intermediate localities between Korea and Samoa. The species is well established on the Korean coast and at the above two localities in Japan. Cole's species has not been found in Asiatic waters.
