Pyuridae Bathypera hastaefera Vinogradova, 1962 (Figures 22 BD, 23B, 24B) Vinogradova, 1962: 206, fig. 3. Kott, 1969: 140 fig.194. Monniot & Monniot 1983: 85, part of specimens included in Bathyfera splendens. Stations (events when several trawling operations per station): 8-21-30 (66)-42-57. The specimens are normally spherical. When fixed the tunic has numerous parallel furrows due to the contraction of the body wall which closely adheres to the tunic (Fig. 22 D). The spicules are uniformly distributed at the colony surface, implanted on a round base and protruding in an asymmetric group of few spines of inequal length (Fig.22B). The spicules reach 600µm in length. The musculature has the same disposition as in B. splendens but the crossed longitudinal and transverse fibres are stronger and more extended on the body wall (Fig. 24B). All other characters are the same in both species taking in consideration the individual variations: branchial sac (Fig. 23 B), gut gonads and endocarps.
