cycles, the fourtli developed in part, of the systems only. The inner 

 edge of the septa sends out tral)icules uniting together to form tlie 

 rudimentary cohmiella, Avhicli is, however, frequently absent. Dis- 

 sepiments thin liut complete, moderately abundant. Gemmation ex- 

 ternal, at all heights, but generall_y near the calicle; abundant, one 

 specimen having as many as eleven buds; some good-sized specimens, 

 however, show none ; as, for instance, the one figured on Plate III. 

 Height of largest sjiecimen 4 cm., diameters of calicle C and 7 nun.

The generic affinities of this coral are a little doubtful. By its 

 general aspect it reminds one of Cladocora, or rather Goniocora ; but 

 according to the classification generally adopted, it is widely sepa- 

 rated from it on account of the entire border of the septa. In its 

 general features it approaches the genus Oncliotrochus Duncan ; ))ut 

 this is described as destitute of endotheca, and therefore placed 

 anion"' the Turbinolians.

By constituting the section of Stylasteracefe of Milne-Edwards and 

 Haime into a separate family, the Oculinidiv become restricted to tlie 

 ()culinacea3 of these authors, and Ibnn thus a much more homogeneous 

 and natural group.
