L 266 Dr. Johnston's Catalogue of Zoophytes. 



The surface is commonly even and smooth, but I have a fine specimen over which there 

 are scattered irregularly, many processes a quarter of an inch in height. They arise from 

 within the cells, are simple, horny, and tubular, but closed at the top. Ellis conjectured 

 they were the ovaries, but this is not likely. 



7. F. unicornis, crust thin, white and calcareous, the margin divided ; cells oval, in rows, 



with a blunt hollow conical process at the summit of each. One-toothed Sea-matt. 

 F. unicornis, Fleming in Edin. Phil. Journ. ii. 87. Flem. Br. Anim. 536. 

 Hab. On stones at low water-mark. 



Forms smaller patches than the preceding, from which it is otherwise readily distinguish- 

 ed by the form of the cells. 



8. F. spinifera, crust thin, spreading irregularly, membranous, brown ; cells oval, small, 



the margin encircled with numerous stout spinous processes as long as the breadth of 



the cell (tab. nost. ix. fig. 6). 

 Hab. On stones at low water mark. 



The spines are straight, equal and rigid. It is a species hitherto unobserved, but pos- 

 sesses characters which, in my opinion, keep it quite distinct from every other. 



9. F. hispida, polypidom fleshy, brown, spreading ; cells remote, aperture circular, con- 



tracted, " armed at the top with spinous processes." 

 F. hispida, Flem. Br. Anim. 537 : Jameson in Wern. Mem. i. 563. 

 Hab. On Fucus serratus et vcsiculosus at low water mark. 



This species is the most favourable for observing the structure of the polypes, which are 

 very pretty and vivacious. They are perfectly white, and are furnished with numerous 

 filiform tentacula arranged in a bell -shaped circle. The spines appear to me to arise from 

 the body of the cells, and not from the aperture ; they are conical and soft (tab. nost. ix. 

 fig. 7). 



15. FARCIMIA. 



1. F. fistulosa, polypidom erect, regularly dichotomous ; joints constricted, the inter- 



tervening spaces long, cylindrical, with lozen-shaped immersed cells regularly disposed. 



Bugle Coralline. 

 F. fistulosa, Flem. Brit. Anim. 534. 

 Tubularia fistulosa, Linn. Turt. Lin. iv. 666 ; Turt. Br. Faun. 210 ; Stew. Elem. ii. 



438. 

 Cellaria farciminoides, Soland. Zooph. 26. 

 C. salicornia, Lam. Hist. Nat. ii. 135 ; Lamowr. Corall. 55 ; Hose, Vers, iii. 129. t. 28,./ 



6, copied from Ellis ; Stark, Elem. ii. 439. 

 Bugle Coralline, Ellis, Corall. 43, t. xxi. 

 Hab. On Corallines from deep water, rare. 



Height of our specimen a little more than one inch, white, fibrous at the base ; branches 

 erecto-patent, straight. One of the finest among British Zoophytes.
