PLATE XXXIX. 



Figs. 1-3, 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. 



Fig. 4. Diploria conferticostata, var. columnaris, var. nov., natural size. 



Figs. 5, 6. Trochoseris catadupensis, sp. nov. Fig. 5, view from side ; Fig. 6, view 

 ofcalice; both natural size. 



PLATE XL. 



Figs. 1-4. Leptophyllia agassizi, sp. nov. Fig. 1, general view of specimen; 

 Fig. 2, costse enlarged, shows their trabecular nature and some 

 synapticulae between them ; in many instances at the surface the 

 trabeculae are not fused together, in others they are ; synapticulae 

 are more abundant than is represented; Fig. 3, a portion of a cross 

 section magnified 3| times ; Fig. 4, several septa more highly magni- 

 fied, to show the synapticulae. It is doubtful if there are any dissepi- 

 ments, though some may be present. 



Figs. 5-7. Turbinoseris cantabrigiensis, sp. nov. Fig. 5, view from side, natural 

 size ; Fig. 6, costae (peripheral ends of the septa) enlarged, to show 

 the synapticulse between them ; Fig. 7, portion of a section of a 

 corallum to show synapticulae between septa, magnified about 8 

 times. There also appear to be occasional perforations near the 

 inner terminations of the septa. 



Figs. 8-10. Turbinoseris jamaicaensis, sp. nov. Fig. 8, view of specimen from 

 side, natural size ; Fig. 9, view of calice from above, If natural size ; 

 Fig. 10, costae (peripheral ends of septa) magnified to show synap- 

 ticulae between them. 



PLATE XLL 



Figs. 1-3. 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. 

 Figs. 4-6. Dendracis cantabrigiensis, sp. nov. Fig. 4, a fragment of a rather thick 



branch ; Fig. 5, a young slender branchlet ; both natural size; Fig. 6, 



several corallites and surface magnified.
