Silhouetta uvacarpa Millard & Bouillon, 1973: 25 , fig. 3A–D, pls 2–3.— Calder, 1988b: 17, figs 13–14.— Schuchert, 2007: 239, fig. 17.

Silhouetta puertoricensis Wedler & Larson, 1986: 91 , fig. 9Aa–b.

Material examined. Stn. 7: 25.03.2008 —four small stems, each with 1–2 hydranths, one bearing clusters of gonophores, on concretions.

Type locality. Silhouette Island, Seychelles.

Remarks. The present material is too scarce to allow a new description of this species. Silhouetta uvacarpa is easily recognizable due to the following characters: the tentacles are filiform and arranged in two or more closely-set whorls below the hypostome; the gonophores (medusa buds) arise from both the stem and branches, in clusters borne on quite long pedicels.

For descriptions of S. uvacarpa , see Millard & Bouillon (1973) and Calder (1988b). Schuchert (2007) summarized the actual data available on this species. Additional life cycle studies are necessary in order to describe the mature medusa.

Distribution. Seychelles ( Millard & Bouillon 1973), western Atlantic ( Calder 1988b), western Pacific (Kirkendale & Calder 2003).
