1873.] DUNCAN — west-inbia tertiary. 559 



The epitheca is rudimentary, and barely exists. 



The wall is thick. 



Inferiorly, the tissues around the peduncle are usually worn off. 



Height of full-grown specimen, 1 inch. Length of calice ^ inch. 

 Breadth -fo - T 5 ^ inch. 



Log. Limestone of St. Bartholomew's, West Indies. 



In the collections of the University of Upsala and of Mr. P. T. 

 Cleve, Stockholm. 



The immature specimens of this species resemble the lower half 

 of the full-grown, and are compressed and wedge-shaped. 



2. Turbinoseris major, spec. nov. PI. XXI. fig. 13. 



The corallum is pedunculate, tall, narrow, conical, and compressed. 



The calice is elliptical in outline and deep. 



The septa are slightly exsert, crowded, alternately large and small, 

 and they pass down deeply into the fossa. 



Their laminae diminish in size from the margin inwards. 



There are five cycles of septa in six systems. 



The synapticulse are scanty. 



The costse are delicate, close, subequal, and the larger are flat and 

 faintly granular. All are connected by numerous horizontal and 

 sometimes oblique synapticulse. 



The wall is very thick. Epitheca quite rudimentary. 



Height 1^ inch. Length of calice y 9 ^ inch. Breadth T 6 ¥ inch. 



Log. Limestone of St. Bartholomew's. 



In the collection of the University of Upsala. 



3. Turbinoseris GRANDis, spec. nov. PI. XXII. fig. 14. 



The corallum is short, very broad, and compressed, and has a sharp 

 peduncle. 



The calice is elliptical in outline ; and its margin is not quite hori- 

 zontal, but is thick. 



The fossa is shallow. 



The septa are numerous, crowded, alternately large and small, and 

 the larger end internally with swollen terminations along an axial 

 space. There are five cycles, and a few septa of the sixth, in six 

 systems. AH are joined by numerous synapticulse ; and the smaller 

 septa join the larger occasionally. 



The costse are subequal, broad, close, and swollen at the junction 

 of the numerous synapticulse. 



The epitheca exists in some specimens. » 



Usually the wall is much worn around the peduncle. 



Height of corallum -fo inch. Length of calice 1 T L inch. Breadth 

 T ^ inch. 



Log. In the limestone and conglomerate of St. Bartholomew's. 



In the collections of the University of Upsala and of Mr. P.T. Cleve. 



4. TURBIN'OSERIS ANGTJLATA, spec. nOV. PI. XXII. fig. 15. 



The corallum is short, turbinate, compressed, and finely pedunculate. 

 The calice is widely open, very shallow and elliptical in outline ; 

 and the margins are somewhat angular, especially at the long axis.
