Dr. P. M. Duncan on some Fossil Corals from Sinde. 3801 
10. Antillia dentata, var., nobis. 
Quart. Journ. Geol. Soc. vol. xx. p. 29. 
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, nu. sp. Pl. 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 coste. 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. Coste alternately large and very small, 
there being twelve large and usually twelve small; the larger 
are much produced. Width of calice and of large corallites 
32; 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. Pl. 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 coste 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 1-3 inch; height +45— 
=*s 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. 
Kurrachee. Coll. Brit. Mus. 
14. Hydnophora Dane, n. sp. Pl. XIX. fig. 2. 
The corallum is tall, very thick, and its upper surface is small
