bably tlie bnds by which the coral grows in length. Sp. F. graci- 

 lis Gr. von der Brasilianischen Küste. 



Acabaria e fam. Melith. The coral very slender, branclied, 

 dichotomoua, expanded in a plane; branches and branchlets very 

 slender, compressed, with short, swoUen joints, more prominent on 

 the older stems. Bark thin, hard, smooth. Cells short, broad, 

 subcylindrical, truucated, in a Single series on each edge of the 

 branches and branchlets, rather close together. Axis calcareous, 

 solid, red, longitudiually gi-ooved; internodes short, swollen, spongy. 

 Sp. A. divaricata Gr. Quito. 



Anicella Qidim. Isid. Coral far-like; dichotomously brauched; 

 branches separate, divaricating, in the same plane, arising from the 

 short, i'ather sunken joints. Bark thin, hard, smooth, longitudinally 

 grooved. Cells minute, subcylindrical, short, produced in a narrow 

 alternating series, on each edge of the branches and "branchlets. 

 Axes calcareous, solid, with longitudinal grooves; internodes very 

 short, contracted, bark-hke. Sp. An. australis. Port Essington. 



Der folgende Band der Annais enthält (p. 21 — 23) 

 unter demselben Titel die Diagnose zweier anderer neuer 

 Genera (Gorgoniden mit Kalkachse). 



Itayne rella, Coral much branched, fan-shaped, expanded 

 in a plane : branches and branchlets piunate ; branches diverging, 

 subcylindrical, slender, nearly of a uniform size ; branchlets opposite 

 or alternate, diverging. Bark thin, with an even, very slightly cor- 

 rugated surface, internally finely granulär. Polype-cells prominent, 

 roundish, close together, diverging irregularly on all sides of the 

 slender branches; apex rather conical, contracted, with a central 

 dot. Axis calcareous, hard, white, with well-marked longitudinal 

 grooves. Sp. B. aurantia Gr. von der Bass-Str. 



Brandella. Coral very much branched, very slender, 

 linear; branches diverging, pinnate, and nearly parallel to each 

 other ; branchlets pinnate, opposite or alternate, diverging at nearly 

 right angles, often sinuous, inosculating, uniting the diverging pa- 

 rallel branches into an irregulär network. Bark, when dry, very 

 thin, almost membranaceous, smooth, and slightly wrinkled. Polype- 

 cells on all sides of the branchlets, alternate or opposite, cylindri- 

 cal, short, smooth externally, with a convex 8-valvated top. Axis 

 very slender, thread-like, except the main stems, calcareous, hard, 

 pale horn-colour, very brittle. Sp. B. intricata Gr. von der Bass- 

 Strasse.
