316 Lcuckart: Bericht üb. d. Leist. in d. Naturgeschichte 



Tel es CO. The coral shrub-like, furcately branched from the 

 base, the polype-cells terminating the branches and branchlets. Hic- 

 her T. anrantiaca Lmx., T. ramulosa VeiT., T. pelagica Lmx. 



Telescella Gr. The coral erect. with successive spreading 

 Clusters of branches, -which are ramulose on the sides. Mit T. no- 

 dosa Verr. (Ist nach Verrill's neuesten MittheiluDgen Proceed. 

 Essex Inst. Vol. VI. p. 82 , eine sehr zweifelhafte Art , zu deren 

 Aufstellung wahrscheinlich ein kleines Anneliden- oder Amphipo- 

 dengehäuse Veranlassung gegeben hat.) ^ 



Alexella Gr. The coral erect, simple, with short, cylindrical 

 adpressed polype-cells on the side of the stem, generally opposite 

 each other, or scattered; soine have onc or more cells produced 

 into a sbort lateral branch. Mit A. Smithii Gr. 



Ebenso macht Gray (Proceed. zool. Soc. 1867. 

 p. 125, 126) einige nachträgliche Bemerkungen über Co- 

 ralliiim Johnsoni und schlägt dabei vor, das frühere Gen. 

 Corallium folgendermaassen einzuthcilen: 



Corallium Lam. The polypes slightly elevated from the bark 

 and scattered on all sides of the branches. C. rubrum L. 



Pleurocorallium Dana. The coral branching in a plane. The 

 polypes scarcely raised, confined to one surface, mostly near the 

 apex of the very small branchlets and often in twos. PI. secun- 

 dum D. 



HetnicoralUum n. The polypes pi'ominent, ovate-cylindrical, 

 often clustered, all distributed on one side of the branches. H. 

 Johnsoni Gr. 



Unter dem Namen Kera t o is is Groyi beschreibt Perc. 

 Wright eine mit Isis nahe verwandte Gorgonide aus 

 der Tiefe der Küste von Setubal (Ann. and Mag. nat. 

 bist. T. III. p. 23 — 25 mit Holzschnitt). Das neue Genus 

 ist vornämlich durch die röhrenförmige Bildung der Kalk- 

 glieder und die Bewaffnung der Einzclthiere ausgezeich- 

 net und trägt folgende Diagnose : 



Gen. n. Keratoisis P. W. Coral branched, irregularly fur- 

 cate; axis jointed, composed of horny and calcareous portions; the 

 latter are hollow, smooth, varying considerably in length and raain- 

 taining their form after maceration in caustic alcalies, the branches 

 are given off from the calcareous portions. The coenenchyma is 

 well developed and contains a large nuraber of calcareous spicu- 

 les. The polypes are irregularly and somewhat densely grouped 

 all round the axis; they are of large size and are completely cove- 

 red with spicules, which are closely packed side by side. A va- 

 riable number (nine to eleven) of long fusiform spicules Surround the
