Notice of some new Corals from Madeira discovered by J. Y. John- 

 son, Esq. By Dr. J. E. Gray, F.R.S. &c. 



Mr. James Yate Johnson of Madeira having kindly sent me some 

 Corals from that island, I herewith send you the following short 

 notice of some specimens which do not appear to have been hereto- 

 fore inscribed in the Catalogues. 



1 . Corallium Johnsonii. 



Coral branched, subflabelliform. Branches nearly simple, sub- 

 parallel, flexuose, with a few very short ascending branches scattered 

 on the sides of the upper surface. Bark yellow, granular, with three 

 or four rows of rather convex polype-cells on the upper surface of the 

 branches only. Axis white. 



Hab. Madeira. 



This Coral is at once known from Corallium rubrum on account 

 of its polypes being placed only on one side of the stem, as is the 

 case with Corallium secundum of Dana from the Sandwich Islands ; 

 but it is easily distinguished from the latter by the colour of the 

 bark and axis, and the thick, elongated, subsimple, subparallel 

 branches. 



2. Antipathes (Cirri]? at hes) setacea. 



Coral simple, elongate, setaceous, straight, erect, closely covered 

 with short conical spinules. Length 18 inches. 

 Hah. Madeira. 



"We have recently received from Mr. Edwin Todd, from Turk's 

 Island in the West Indies, a specimen of Antipathes which differs 

 from the former only in being rather more slender and very much 

 more elongate, being more than 9 feet in length. It may be a di- 

 stinct species, for the spinules appear to be rather closer and smaller ; 

 but I am rather inclined to regard it, for the present, as a variety of 

 the above, and it may be called var. (3. occidentalis. 



Both specimens are at once known from Antipathes spiralis by 

 their slenderness, the abundance of the spinules, and their being 

 straight, without the slightest tendency to assume a spiral form. 



3. Antipathes gracilis. 



Coral rather fan-like, expanded, very slender, repeatedly forked. 

 Branches very slender, elongate, subsimple, tapering; stem and 

 branches covered with very close, rather elongated spinules. 



Hab. Madeira. 



The Coral about 6 inches high, rather fan-like, on a single plane ; 

 the stem slender, about as thick as a thick bristle, subalternately 

 branched, with the rows of branches on the outer side, giving them 

 the appearance of being forked ; the branches and branchlets elon- 

 gate, very slender and subsimple, and gradually tapering till they 

 are quite hair-like.
