CORYNID.E I CORYNE. 43 



description of Agarclh is, " Radix, s. a. s. Frondes primaries capil- 

 lares, tubulosoe, sesquiunciales vel parura ultra, capillum porcinum 

 crassitie duplo superantes, eandemque crassitiem per totam longitu- 

 dinem servantes, a basi ad apicem totae annulosa-rugosae, obtusae, 

 dichotomae. Rami frondi veluti appositi, basi parumper bulbosi, 

 caeterum frondi primariae similes, ejusdemque crassitiei. Substantia 

 flexilis fere confervoidea ; exsiccator satis tenax, nee, ufc in caeteris, 

 fragilis. Color corneo-viridescens, subpellucidus : Siccata chartse 

 parum vel laxe adhaeret." The applicability of this description to 

 our Coryne is evident, and hence the latter has the following

" Cor. ramosa, nob. ; stirpe ramosa, ramulis apice clavigeris, clava 

 cylindrica, filamentis apice nodiferis obsita, basi gemmifera." " In 

 freto La Manche, fuco adhaerens. A Coryne pusilla, Cuv. (Pallas, 

 Spic. Zool. x. 4 8) unica praeter nostram specie ramosa, differt 

 forma clavje, et gemmis in ejus basi. Cum autem de metamorphosi 

 animalium hujus generis observationes nullas habeamus, species 

 nostra cum C. pusilla eo modo fortasse convenit, ut gemmae, in clava 

 inclusse (unde crassior videtur), ad basin clavae seponantur ideoque 

 C. pusilla in ramosam commutetur." Chamisso and Eysenhardt. 

 Van Beneden thinks that the species has the closest affinity to his 

 Syncoryna Listerii ; they are alike, he says, in habit and in size, 

 but the difference in the position of the ovules is great and important. 

 Our observations, on the contrary, lead us to believe that this 

 character is one of no value. Van Beneden gives the " coast of Eng- 

 land" as the habitat, but this is a mistranslation of the Latin 

 " freturn Anglicum" of Ehrenberg.
