Dr. P. M. Duncan on some Fossil Corals from Sinde, 801 



10, Antillia dentata, var,, nobis. 

 Quart. Journ. Geol. Soc. vol. xx. p. 39. 

 The coral has a broad base ; the epitheca is well developed, 

 and the columella also. 



From the Sinde Tertiaries, Kurrachee; also from Jamaica 

 (Miocene). Coll. Brit. Mus. 



11. Antillia ponderosa, nobis. 

 Montlivaltia ponderosa, Edwards & Haime. 

 A small and worn specimen is in the British Museum. 

 Sinde. Jamaica, Guadaloupe, and San Domingo (Miocene). 



12. Cladocora Haimei, n. SY>. PI. XVIII. fig. 6. 



Corallites long and very slightly flexuous : the buds are few, 

 and leave the parent singly at an acute angle, but often become 

 attached to it again. Calice circular. Septa small and delicate, 

 the larger being much smaller than their costse. Three cycles are 

 generally complete, and the septa of the third order are smaller 

 than the others. In one specimen the septa are crooked, most 

 probably from post-mortem pressure from without. Columella 

 small, and the pali also. Costse alternately large and very small, 

 therfe being twelve large and usually twelve small ; the larger 

 are much produced. Width of calice and of large corallites 

 •iV inch. 



The species is more closely allied to Cladocora manipulata 

 and C. Michelottii, Edw. & Haime (both Miocene forms), than 

 to any others. 



13. Hydnophora rudis, n. sp. PI. XIX. fig. 1. 

 Corallum thick, its upper surface more convex in the middle 



than at the sides, and covered by numerous monticules of many 

 shapes and sizes, whose base is usually flat, and whose upper 

 extremity is generally sharp, cristiform, and irregular in its 

 direction. The larger monticules are compressed, inclined, and 

 sharp, whilst the smaller are conical. The septa are numerous, 

 very slightly projecting, equal, and usually enlarged at their in- 

 ferior extremity. The costse are seen on the under flat surface 

 of the corallum as faint parallel lines, and are alternately large 

 and small. Width of the valleys from ^-^ inch; height -j^- 

 -j% inch ; ten septa in \ inch. Thickness of corallum |-1| inch. 



The species is closely allied to the next, to H. plana, and to 

 the recent H. Demidoffi, Fischer.

14. Hydnophora Dana, n. sp. PI. XIX. fig. 2. 



The CO rallum is tall, very thick, and its upper surface is small
