TRIBE 1 1. CARYOPHYLLACEA. 39 



The specimens in the Expedition collections, agree nearly with the 

 above description by Ehrenberg. They are about an inch and a half 

 high, and consist of a few calicles half an inch in diameter, and 

 smaller. In those of large size there are ten to twelve large lamella?, 

 with four to five narrower intermediate. The aperture is circular or 

 elliptical instead of angular; the exterior is striate and a little sca- 

 brous, with the stria? punctate. The specimen from the Feejees has 

 the calicles about half an inch long, while in that from Singapore 

 they are from an inch to an inch and a half in length, and are arcuate. 



Oculina coccinea, Ehrenberg, G. xlviii. sp. 6. 



6. DENDROPHYLLIA DIAPHANA. (Dana.} 



D. humilis, subramosa, fusca, polypis 3-4'" latis. Corallum caliculis 

 cylindricis, vix ellipticis, extus tenuissime striatis et scabriculis, parie- 

 tibus tenuibus et diaphanis, margine integris ; celld profundiore (fere 

 ") ; lamettis 6-10 majoribus et 2-3 intermediis valde minoribus. 



Low, subramose, fuscous, polyps 3 to 4 lines broad. Corallum a 

 cluster of cylindrical or slightly elliptical calicles, very finely striate 

 without, and somewhat scabrous, sides thin and diaphanous, margin 

 entire; cell quite deep (nearly an inch); 6 to 10 larger lamelte, 

 and 2 to 3 intermediate much smaller.

The thin diaphanous walls of the calicles are quite peculiar ; the 

 specimen seen is a cluster of seven or eight polyps, each about 

 half an inch long. The cell appears peculiarly open, the large 

 lamellae being few in number, and the intermediate very much nar- 

 rower. 



7. DENDROPHYLLIA KUBEOLA. (Quoy 4- Gaymard.} 



D. cespitosa, vix ramosa ; polypis 2'" latis, subrubris, tentaculis tenuibus. 

 Corallum caliculis cylindricis, 2 3'" longis, substriatis, apice truncatis, 

 margine integris; celld conica ; lamettis majoribus alternis.
