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

 edge of the septa sends out trabicules uniting together to form the 

 rudimentary columella, which is, however, frequently absent. Dis- 

 sepiments thin hut complete, moderately abundant. Gemmation ex- 

 ternal, at all heights, hut generally 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 specimen 4 cm., diameters of calicle G and 7 nun.

Off Double-Headtd Shot Key, in 315 fathoms (dead specimen). 



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

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

 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 Onchotrochus Duncan ; hut 

 this is described as destitute of endotheca, and therefore placed 

 among the Turbinolians.

By constituting the section of Stylasteracese of Milne-Edwards and 

 llainie into a separate family, the Oculinidae become restricted to the 

 Oculinaceaj of these authors, and form thus a much more homogeneous 

 and natural group.
