MARINE ZOOLOGY The gland is foliated and of an opaque whitish yellow, and somewhat granular. The papilla^ when observed were sliglitly contracted, and in that condition, which appeared to be more or less normal, they became slightly constricted at each band, thus giving an undulating outline to the papillae ; the reason for this lay in the fact that the internal gland was narrower at those points. The dorsal tentacles are almost twice the length of the oral ones; they are long and linear and with obtuse tips, the latter being transparent white with a band of opaque white below, and about midway down there is a patch of seaweed-green colour. In 1 900 about half a dozen specimens were taken upon Plum- ularia pinnata, to which had been attached about a dozen of their egg-bands. In the next year two more specimens, together with Doto coronata, were taken at low water, upon Obel'ta longissima. In the former instance the resemblance of the papilla to the egg capsules of the hydroid was rather striking. Rare. Hastings. 166. Galvina tricolor, Forbes. Length of specimen i inch. General appearance : animal of a pale orange or bufF colour ; papillae inflated and pointed, those in the front half or two-thirds of the body being tipped with orange ; the hinder papillae also being orange-tipped, and in addition speckled with dark brown. The dorsal tentacles are colourless and have obscure internal lines of opaque white running down each, to bulbous bases and the eyes. Tail colourless. Closer ex- amination of a papilla shows a constric- tion near the end, the end portion being divided into three zones of colour ; that nearest the constriction is opaque white with brown-black spots, the next is of orange or pale yellow, and the one at the apex colourless and transparent ; the lower portion of the papilla is semi-opaque white, a deeply lobed gland of a pale straw colour being occasionally seen, which sends a single straight stem-like lobe to the apex. A single specimen trawled from moderately deep water. Rare. Hastings. 167. Coryphella rufibranchiahs, Johnston. Eolh pellucida. Alder and Hancock. Eolis gracilis, Alder and Hancock. Length of animal, i^ inches ; body semi-transparent white. The papillae are rather long and linear, the apex is pellu- cid white, below which is nearly always a ring of opaque white, of a granular 103 character, and internal. The sheath is transparent colourless, and the gland of a bright orange-red or coral colour, un- even in outline, squared at the top and leaving only a small margin of the sheath showing. The dorsal tentacles are wrinkled and have a faint tinge of orange, the tips being granulated with opaque white ; they area little longer than the oral op?s, which are also tipped with opaque white granules upon the inner and upper side ; the foot processes are long. In March 1897 an abnormally coloured specimen was obtained from the coralline zone. In this speci- men the veil, both pairs of tentacles, and the upper side of the end of the tail were coloured a beautiful mauve violet, excepting the apices of the tentacles which were opaque white. Some of the papillae also partook somewhat of the mauve colour. Since the above date another specimen taken upon the shore (not its usual habitat) showed the same tendency towards mauve colouring. The deep-water form is much longer, and has papillae more filamentous than the variety from shallower water. Habitat from moderately shallow water to the coralline zone. Occasionally plentiful. Hastings. 168. Coryphella landsburgi, Alder ^nd Han- cock. The length of this beautiful little creature is not much more than -^ inch. Animal in part colourless, semi-transpar- ent, but coloured along the sides of the body, the papillae and their bases, and over the head and hinder part of the body, with light violet or mauve. Looked at more closely, the central gland is orange, the sheath of a light violet, and there is a band or patch of opaque white near the apex. Both pairs of tentacles are violet for one-third of the way up them, the upper part being transparent white, with a slight patch of opaque white at the apex ; foot processes moderately long. Trawled half a mile from shore upon flustra, where it was only detected by its colour. Rare. Hastings. 169. Facelina coronata, Vorhes and Goodsir. In summer this gorgeously coloured species is always more or less with us. The length is i^ inches; the body is pellucid grey slightly speckled with blue. In the papillae, which are tapering, the core varies in colour from light to dark orange or red-brown ; the sheath is pellu- cid grey, with an irregular splash of very
