 A HISTORY OF SUSSEX and do not differ in appearance from the axis. Colonies in texture are rather india- rubber-like. Common. Hastings. Valkeriid^ 1 06. Valkeria uva, Linnaeus. Favourite habitat, over-running Corall'ma afficinalis. Zooecia ovately cylindrical, slightly narrowing towards the aperture. Rather common. Hastings. Valkeria uva var. cuscuta.* Hastings. ENTOPROCTA PEDICELLINEA Pedicellinid^ 107. Ped'ueU'ina cernua^ Pallas. Species over-running Corall'ma officinalis, throwing up short pedicels, each bearing a polypide and a zooecium at the top. The pedicel is spinous, and as in the other members of this genus, flexible, which is demonstrated by the zooid making a motion as of bowing or nodding. In this species the pedicel tapers slightly towards the top, but is not constricted at the apex, as in P. nutans ; and further the zooid is greatly more protuberant upon the anal than upon the oral side. Pedicellina cernua var. glabra, having a smooth pedicel, also occurs at Hastings together with the type. Both are common. 108. Pedicellina nutans, Dalyell.* Hastings. 1 09. Pedicellina gracilis, Sars.* Hastings. ECHINODERMA HOLOTHUROIDEA 1. Synapta inbarens, O. F. Mailer. Specimens wormlike, of a pale flesh colour ; about 2 inches in length and ^ inch in diameter. The body has no podia ; the tentacles are twelve in number and bi- laterally lobed. Spicules occur in the form of anchors and perforated plates ; the latter are egg-shaped in outline, and both are devoid of serrations. On some occasions the fisher- men's nets are choked with these creatures. Rare generally. Hastings. 2. Cucumaria pentactes, Forbcs.t Brighton. 3. Cucumaria lactea, Forbes and Goodsir. Animal about i^ inches in length, of a light chocolate-brown colour. Podia alter- nate, in five rows ; discs of suckers, white. There are ten dendriform tentacles which, together with the disc, are of a light buff colour freckled with brown, the tentacles becoming quite pale towards the tips. The spicules are nodulated, perforated plates. A single specimen trawled half a mile from shore. Rare. Hastings. 4. Thyonefusus, O. F. Muller. Specimens about 3 inches in length, flesh- coloured to pink ; test rather delicate. The podia are numerous and scattered generally over the body, but in some cases show a tendency to longitudinal arrangement. The tentacles are dendroidal, and ten in number, two of them being smaller than the others and having red cores ; these two tentacles are constantly applied to the mouth. The tentacles and disc are powdered with brown over the pink ground, and the mouth is of a dark brown. The spicules are sub-rectangular tables with two-legged central pieces. From the Diamond Ground j rare. Hastings. 5. Thyonefusus {^), O. F. Mtlller. Specimens white, barely ^ inch in length, probably immature. The podia are plenti- ful and scattered, displaying however some longitudinal arrangement. The spicules are perforated tables with two - legged central pieces, the immature ones being somewhat lozenge-shaped, and the mature ones ovate to sub-quadrangular. There is some little varia- tion between the tables of these specimens and those of the last species, but they are probably referable to the same species. As- sociated with scallops. Shoreham. 6. Phyllophorus drummondi, Thompson. Specimens white, about 5 inches in length, tapering below ; test rather tough. The podia are scattered rather thinly, and occur to some extent along longitudinal lines. Tentacles seventeen in number, dendroidal, alternating in size ; stems of tentacles rather brown, mouth of a dark brown. Spicular tables rather large, circular to sub-quadrangular in outline. From the Diamond Ground ; rare. Hastings. Kinahan.t Holothuric Brighton. nigra, ASTEROIDEA AsTERINIDit 8. Palmipes placenta, Penn. Species with five arms connected by a
