PLATE XXXIX, 
Diploria conferticostata, sp. nov. Figs. 1 and 2, views of two different 
coralla, natural size; Fig. 3, 1 cm. of a series on specimen repre- 
sented by Fig. 1, enlarged. 
Diploria conferticostata, var. columnaris, var. nov., natural size. 
Trochoseris catadupensis, sp. nov. Fig. 5, view from side; Fig. 6, view 
of calice; both natural size. 
PLATE XL. 
Leptophyllia agassizi, sp. nov. Fig. 1, general view of specimen; 
Fig. 2, coste enlarged, shows their trabecular nature and some 
synapticulee between them; in many instances at the surface the 
trabecule are not fused together, in others they are; synapticule 
are more abundant than is represented; Fig. 3, a portion of a cross 
section magnified 8} times; Fig. 4, several septa more highly magni- 
fled, to show the synapticule. It is doubtful if there are any dissepi- 
ments, though some may be present. 
Turbinoseris cantabrigiensis, sp. nov. Fig. 5, view from side, natural 
size ; Fig. 6, coste (peripheral ends of the septa) enlarged, to show 
the synapticule between them; Fig. 7, portion of ẹ section of a 
corallum to ‘show ‘synapticule between septa, magnified about 8 
times. There also appear to be occasional perforations near the 
inner terminations of the septa. 
Turbinoseris jamaicaensis, sp. nov. Fig. 8, view of specimen from 
side, natural size; Fig. 9, view of calice from above, 14 natural size; 
Fig. 10, cost» (peripheral ends of septa) magnified to show synap- 
ticule between them. 
PLATE XLI. 
“Mesomorpha' catadupensis, sp. nov. Fig. 1, view from above; Fig. 2, 
view of corallum in profile, both natural size; Fig. 3, several calices, 
magnified nearly 3 times. 
Dendracis cantabrigiensis, sp. nov. Fig. 4, a fragment of a rather thick 
branch; Fig. 5, a young slender branchlet; both natural size; Fig. 6,
