BRITISH ZOOPHYTES. 87 



and equidistant whorls ; about 5 pedicels in each whorl. 

 Calycles bell-shaped, with 12 pointed teeth. 



This is the " Horse-tail Coralline " of Ellis, and this 

 name, showing its similai'ity to the Eqiiisetnm, gives a 

 good idea of the appearance of the zoophyte. 



6. C. FLEXuosA, Eincks. Plate TV. fig. 5. 

 Laomedea gelatinosa (var. a. 0. J., B. Q. C), L. 



flexuosa {T. E., All, McA.). 



Hab. : Common. Height 1 in. Stem horn colour, 

 somewhat bent and giving off pedicels at the joints, 

 ringed at the base and above the joints of the pedicels. 

 Calycles alternate with a plain rim, borne on ringed 

 pedicels. Tentacles webbed towards the base. Female 

 gonothecas large, oval, with a straight top. 



This is a very common species, found in the littoral 

 zone on almost every part of the coast, and spreading 

 in dense forest-like masses upon weeds and stones. 



7. C. ANGULATA, Hiticks. Plate IV. fig. 6. 

 Laomedea angulata {McA.). 



Hab. : On Zostera marina. Ramsay, Torbay (Hincks), 

 Jersey {A. M. N.), Menai Straits {A. S. P.) . Height i— | 

 in. Stem bent so as to form distinct obtuse angles, 

 with long internodes. Einged pedicels given off at the 

 angles. Polypite with about 24 tentacles. 



A peculiarity of this species is that the extremity of 

 the stem is prolonged into a long tendril-like clasper, 

 thickened towards the end and annulated at the base. 

 Mr. Hincks states that he has seen specimens in which 

 the stem was only | in. in length, with a tendril ^ in. 

 long ; and I have myself observed a similar dispropor- 

 tion. 



8. C. NEGLECTA, Aid. 



Laomedea neglecta (Aid.).
