42 ANTHOZOA IIYDROIDA. 



tinctly perceivable. The polype is of an amaranth-red colour. The 

 polypidom is horny and thickish (tres-consistant), while it is papy- 

 raceous in the C. pusilla ; and it is also regularly annulated in some 

 places, almost as in the Campanularise. (This is the species repre- 

 sented in our Plate II., and is probably the true C. pusilla.)

I have not seen either the description or figure of Sars, the only 

 author who has described this species ; but I have specimens of a 

 Coryne from Mrs. Griffiths which appear to be referable to it. 

 They are found on the coast of Devonshire. The polypidom is erect 

 and plant-like, rooted by a creeping tortuous fibre, rising to the 

 height of an inch and a half or even two inches, branched, the 

 branches alternate, erecto-patent, spreading on all sides, and each 

 terminated with the polypous head. The stem and branches are of 

 the same calibre : they are as thick as ordinary thread, filiform, 

 horny, and ringed throughout with close-set regular annuli. The 

 branches are usually a little constricted at their origins. The 

 polype is oblong, freer than ordinarily from the tube, and separated 

 by a narrow neck, with from ten to twelve, or more short tentacula 

 scattered over the surface. The ovules are round, shortly pedicled, 

 produced at the roots of the tentacula ; and on a few heads they 

 surrounded the base just underneath the inferior range of these 

 organs. Plate VI. Fig. 4, 5. 



The size to which this attains, and its more decided annular 

 character, may be ascribed to a favourable locality; and at all 

 events a character which is only a higher development of one com- 

 mon to the genus can scarcely be considered specifical. I received 

 my first specimen of the Coryne before me from Mr. Thompson of 

 Belfast, who finds it parasitical on littoral sea- weeds and corallines in 

 Strangford Lough and on the Dublin coast, and from this imperfect 

 specimen the figures 6, 7, in Plate VI. were taken. The specimen 

 was of an olive-green colour. It answered so well to the character 

 of the Tubularia muscoides of Linnaeus that it was referred without 

 hesitation to that species ; and it now comes to be a question 

 whether this Coryne and the Tubularia muscoides are not identical. 



With the assistance of Dr. Baird, who has sent me Agardh's 

 description of this Tubularia, and a tracing of his figures, I can 

 answer the question in the affirmative. Linnaeus defines it 

 "Tubularia culmis subdichotomis, totis annuloso-rugosis." The
