 species clearly definable, and which were described and figured for the most part in the 

 'Annals and Magazine of Natural History,' April 1864, are without satisfactory geolo- 

 gical horizons. They swell the list of the fossil Corals of the province ; and it is to 

 be hoped that, in years to come, they will be satisfactorily located in their proper 

 stratigraphical position. They were derived from the neighbourhood of Karachi, and 

 doubtless came from the Gaj series. Some of them are figured on Plate XXVI. and 

 Plate XXVII. 



XIV. A Description of the Fossil Alcyonaria from the Gdj Series of Sind. 



There are several specimens of Alcyonaria from the Gaj group of strata, the size 

 of which indicates a very flourishing fauna ; they are closely allied to those of the 

 Italian, Sicilian, and Australian middle and later Tertiary deposits. Seguenza, in his 

 ' Disquisizione Paleontologicha intorno ai CoraUarii fossili della rocca Terziaria del 

 distretto dl Messina' (Torino, 1863), gives a summary of the fossil forms known to him 

 and to previous observers, such as Goldfuss and Michelotti; and in 1875 the author 

 of this Monograph published descriptions of fossil Alcyonaria from Australia and New 

 Zealand in the ' Quarterly Journal of the Geological Society,' vol. xxxi. : in 1864 he 

 had noticed the occurrence of Corallium pallidum in the Sind Tertiaries in the ' Annals 

 and Magazine of Natural History' (April 1864).
