390 ZOOPHYTES. 



Cespitose, scarcely ramose; polyps about 2 lines broad, reddish; ten- 

 tacles slender. Corallum with cylindrical calicles, 2 to 3 lines long, 

 somewhat striate, truncate at summit, margin entire; cell conical; 

 the larger lamellae alternate with smaller. 



New Zealand. Quoy 4- Gaymard. 



According to the figure by Quoy and Gaymard, this species occurs 

 in small groups of calicles. The exsert mouth when the animal is 

 expanded is very prominent, and has the shape of a reversed cone. 

 The edge of the calicle is described as very even and entire.

APPENDIX. Species, observed only as a simple polyp. 



D. scabrosa. {Dana.} Turbinato-cylindrical, half an inch high, and 

 the same in breadth ; exterior finely striate and villoso-scabrous or 

 spinulous, margin nearly entire; cell deep (nearly half an inch) la- 

 mellae very unequal, about twelve larger, and mostly three smaller 

 intermediate, the latter denticulate. Colour, when fresh, nearly black. 

 The sides are much thicker than in the diaphana, and cellular. The 

 adult cell probably contains forty-eight lamella. Singapore. Exp.

GENUS IX. OCULINA. LAMARCK. 



CaryophyUidce aggregato-gemmatce ; polypis uni-gemmatis, gemmis sin- 

 gulis seriatim enascentibus et caules elongatas divaricate ramosas 

 cumulantibus. Corolla persolida, super jide levi ; caliculis subcylin- 

 dricis ; lamettis integris, plus minusve exsertis. 



Aggregato-gemmate, one bud proceeding from each polyp, the succes- 

 sion forming elongating stems, divaricately ramose. Coralla solid 

 with the exterior smooth ; calicles subcylindrical ; lamellae entire, 

 more or less exsert. 



The Oculina3 are remarkable for the compactness of their coralla, 

 there being scarcely a cellule within or without, excepting those of
