MARINE ZOOLOGY 



bed tentacles, the latter being dispersed 

 over the body and numbering about nine- 

 teen. Colour semi-translucent white with 

 opaque white dots. The polypary expands 

 over the base of the polypite, below which 

 it is plain or very slightly undulatory, and 

 throughout the lower three-fourths of the 

 stem it is lightly annulated. The polypary 

 is colourless or of a faint buff shade. Upon 

 Tubularia indivisa. Hastings. 



4. Coryne vaginata, Hincks. 



Zoophite 3 inches high, in form resem- 

 bling a spruce fir tree; polypite naked, 

 rose-coloured, with tentacles scattered as in 

 Clava, but short and knobbed at the ends ; 

 gonophores oval and borne amongst the 

 tentacles. Common in rock pools, often 

 densely covered with confervae. Hastings. 



EUDENDRIID/E 



5. Eudendnum rameum, Pallas. 



Polypite naked, tentacles forming a ring. 

 This zoophyte has been aptly compared to 

 a stunted and weather-beaten tree. The 

 stem and main branches are compound, and 

 when covered with the round and orange- 

 coloured gonophores the colony might be 

 likened to a shrub laden with berries. The 

 gonophores are generally borne upon the 

 caenosarc. Common in the trawl from the 

 Diamond Ground and moderately deep 

 water. Hastings. 



6. Eudendnum ramasum, Linnaeus. 



This species suggests a collection of 

 branching twigs. The stem is formed of 

 a single tube, both it and the branches 

 being of a straight and straggling character 

 and of a glossy brown colour. No gono- 

 phores observed. Common upon scallops 

 and rock from deep water. Hastings. 



7. Perigonimus repens, Wright. 



Polypite with a single circle of tentacles 

 distant from the mouth ; polypary rather 

 coarse, of a red-brown colour, and ex- 

 panded over the base of polypite to form a 

 rough cup. Taken upon shell of Nucttla 

 nucleus, in association with Lovenella clausa. 

 Coralline zone ; rare. Hastings. 



8. Garveia nutans, Wright. 



This species requires more than a pass- 

 ing notice. The only localities given for 

 it by Hincks are Inchgarvie, Firth of 

 Forth, and Shetland. It has been taken 

 some three or four times offshore at Hast- 

 ings, upon all occasions climbing over Hy- 

 drallmania and throwing up short branches, 



and not as figured by Hincks from northern 

 specimens with erect and compound stem. 

 The polypites have a single circle of ten- 

 tacles and there is a gradual expansion of 

 the polypary over the base of the polypite. 

 Branches flexuous. The polypites them- 

 selves are conspicuous by their colour, 

 which is orange or carrot colour, and which 

 also extends to the ccenosarc. The gono- 

 phores are likewise orange coloured and are 

 given off from the creeping stolon, emerg- 

 ing from an expansion of the polypary. 

 The Hastings specimens agree fairly well 

 with Hincks' description, but differ in the 

 matter of the compound and erect stem, 

 and in the fact that the polypites were not 

 noticed to nod, from which peculiarity the 

 species takes its name. Somewhat rare. 

 Hastings. 



TUBULARIID.S: 



9. Tubularia indivisa, Linnaeus. 

 Polypite naked with two crowns of 



tentacles, the one oral and the other ab- 

 oral, or midway down the body. Among 

 the latter are borne the gonophores in 

 grape-like bunches. The empty polypar- 

 ium tubes much resemble tufts of stubble. 

 Not a shore species ; the finest specimens 

 are obtained from moderately deep water. 

 Common off Hastings. 



10. Tubularia larynx, Ellis and Solander. 

 Except as regards size and habitat there 



seems little to distinguish this species from 

 T. coronata. The Hastings specimens are 

 very faintly annulated, and little or no 

 branching can be detected. The polypites 

 are naked, transparent, very finely spangled 

 with opaque white ; gonophores round to 

 oval and borne upon short branched pe- 

 duncles. The gonophores and manubrium 

 are rose-coloured, and the former have from 

 not any to four tubercles at their distal ends. 

 The gonozooid or extrusion is oval, con- 

 stricted at the basal end, with twelve long 

 ab-oral tentacles, sometimes less, clubbed 

 at the ends and alternately raised and 

 lowered, by which means this star-like 

 creature stalks about, as upon stilts. At 

 the oral end there are invariably four short 

 thick tentacles, curved inwards. The 

 creature having no bell seems awkward and 

 sluggish, and is apparently intermediate be- 

 tween the fixed and freed forms. This 

 species only visits Hastings in occasional 

 years. In 1897 it appeared in great pro- 

 fusion upon rocks and stones from mid to 

 low tide. Hastings.
