Moseley (3). 
OdontocyathuSj g. n. Corallum with a fascicular columella and three 
crowns of pali free, but with a minute scar of former attachment in the 
form of a deep saucer, with straight sloping sides, and a broad flat base 
composed of fused radiating tuberculate spines, which project like the 
spokes of a wheel all round the base of the wall. 0. coronatus (p. 148), 
St. Thomas, 390 fath. Moseley (3). 
Stephanotrochus, g. n. In this genus, the corallum is cup or saucer- 
shaped, the costae usually well-developed, the septa extremely exsert, and 
the columella absent, or but little prominent. S. diaderna = Ceratotrochus 
diadema, S. discoides = C. discoides, S. platypus = C. platypus^ and S. 
nohilis = C. nohilis (p. 152). Moseley (3). 
CyathoceraSf g. n. The corallum is conical and elongate, without an 
epitheca, or with a partial one only, fixed by a short pedicle, with a well- 
developed columella. C. cornu (p. 156), Rio do la Plata, 600 fath., and 
Twofold Bay, 200 fath. Moseley (3). 
Pleurocyathus, g. n. The corallum is conical, and attached by its side. 
It is entirely covered by a thin epitheca, which rises higher than the 
margin of the calicle. The lower part of the Coral is devoid of stereo- 
plasma or other filling. The columella is composed of several flattened 
pillars. P. hrunneus (p. 159), Banda Island, 60 fath. Moseley (3).

OCULINIDJ]. 
Neohelia, g. n. Corallum with a very abundant and diffuse coenen- 
chym, encrusting the stems of Gorgonoids with very short branches only. 
Calicles with the septa arranged in five systems, which are fused together 
often by the coenenchym. Gemmation irregularly dichotomous. F. par- 
cellana (p. 176), Api Island, 63 fath. Moseley (3). 
Batheiia, g. n. In this genus, the corallum is arborescent and massive. 
The calicles are deep, with four circles of septa, and there is only a single
