| Summary: | Polyzoa atlantica n.sp. (Figures 1–3) Material examined: Holotype: collected in 2004, at 31°36.056' N, 80°47.431' W, specimen #190, deposited in Kamchatka Branch of the Pacific Institute of Geography (KBPIG 1/1384). The colony consists of several ovoid or globular zooids 3–4 mm in diameter that are attached to the test of the solitary ascidians Molgula occidentalis Traustedt, 1882 and Styela canopus Savigny, 1816. The spacing between zooids is variable, zooids are never coalescent, and are attached by a small narrow surface on their posterior side (Figure 1 A, B). Zooids are connected only by inconspicuous thin sheet or stolons that are spread over the substrate. Each zooid has its own test covered completely with firmly attached sand grains (Figure 1 C). The zooids do not possess hair-like outgrowths. The siphons are not discernible on the preserved material and, as a whole, this sandy colony is very inconspicuous and difficult to detect. The body wall is thin, firm, and translucent.
