408 Miscellaneous. 



VeretUlam cynomoriam, Pall. Does not t[iiit the muddy bottoms. 

 Frequent near the lie de Maire and the Goudes at 18 and 20 

 metres. Descends to 80 metres in the north-western region, to- 

 wards the mouths of the Ilhone. Taken in the Bay of Eiscay. 



Pteroides griseum, 13ob. The most abundant Pennatulid on our 

 coasts. Inhabits the mud of the north-west, outside the isles of 

 llatonneau and Pomegue (60-80 metres). Some individuals pene- 

 trate into the sandy mud to the south of Pomegue. The two 

 varieties, hrevisjrinosa and lonylspinosa, are represented ; but the 

 second is the more frequent. 



Pennatula rubra, Ell. Much rarer than the preceding, 



Fennattda ].>]ios2-)liorea,'L. Very rare in the regions of Pteroides 

 grisexin, 



Leptogorriia viminalls, Pall. The muddy and sandy-muddy bot- 

 toms are not the ordinarj- stations of the (iorgonias ; but along the 

 north shore, from L'E.stague to Mejean, wo find, at 40, 50, and 70 

 metres, a Gorgonia with slender branches, which I identify with 

 Lepto(/orgia vbniualis. It is attached sometimes to the sliells of 

 Pectttncidi, sometimes to stones or to tiles dropped from the lighters 

 of 8aint-Henry, The branches are sometimes very long and not 

 much ramified, drooping; in other cases the polyparyis more spread 

 out, like a fan. 



Gorgonia graminea. Lam. Very rare. A few small polyparies, 

 scarcely ramified, are associated with the Leptcgorgin',. 



tSi/mpodinm coraVoides, Pall. On Leptogorgia vhmncdis. 



C. Zone of Gravels, Sands, and Coralligenous Submarine Pocl's. — 

 From 30 to 70 metres. Shores of the isles Pomegue and Paton- 

 neau. Submarine rocks off Montredon. Deep reefs of Mangespeu. 

 Around the Zosterce at Carry, Podesta, and lliou. Station of Coral 

 and Gorgonias. 



Gorgonia graminea, Lam. Very abundant, and sometimes, espe- 

 cially at Eiou, forming very large polyparies. 



Gorgonia verrncosa, Pall. Less abundant than the preceding. 

 The sarcosoma is often of a fine yellow colour. 



Muricea 2>^ucoinus, Lin. Hare. Coralligenous bottoms of Riou 

 and Podesta. 



Coralliwn rubrum, Costa. Isle of Tiboulen ; around llatonneau. 

 From the Cap Couronno to Carry. lliou. 



Sympndium coralloides, Pall. — On all the Gorgonias. 



Paralcyonium elegans. — On incrusted Algse. llatonneau, off Mon- 

 tredon, Eiou. Pretty frequent. 



Alcyonium pahnatum, var. acatde, Marion. This form, which 

 will be considered by some zoologists a true species, I have described 

 in the ' Eevue des Sciences Naturelles.' It is characterized by its 

 incrusting base furnished with zooids, and by its dense tissues 

 closely packed with strong spicules. 



D. Muddy Sands of the open Sea, at depths from 100 to 200 

 metres. — The Alcyouaria diminish rapidly in importance in propor- 

 tion as we quit the bay and descend towards the great depths. The 

 coral makes its appearance at some rocky points, — for example, to
