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

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.

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
