Description
Silhouetta uvacarpa Millard & Bouillon, 1973
(fig. 2D)
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).
