Cyclonia gracilis Stechow, 1921

Stechow (1921b), Zool. Anz. 53, p. 230.

ZSM 20040664 (fig. 3F) on colonies of the Hydrozoa Idieallana pristis (Lamouroux) and Nigellastrum digitale (Busk) in ethanol, U.S. Virgin Islands, St. Thomas Island, Savana Passage, leg. W. Kükenthal & R. Hartmeyer expedition, 24.I.1907.

ZSM 20045173 - 20045180 micro slides with colony pieces, partly on other Hydrozoa (ZSM 20045173 on Idieallana pristis (Lamouroux), ZSM 20045180 on Lytoscyphus marginatus), U.S. Virgin Islands, St. Thomas Island .

Note: It seems likely that the micro slide material origins from the same material as the ethanol sample.
