BRITISH BELEMMTES. 



Mr. Miller also describes, under the name of Actinocamax verus, the incomplete guard 

 of a twelfth Belemnite, from which the part containing the " alveolus" had been removed 

 by decomposition of the nacreous laminae. Before his death this was made clear to the 

 ingenious author, to whom we are indebted for a still more valuable contribution to 

 palaeontology, viz., the essay on ' Crinoidea.' 



For the greatest addition ever made to British fossil conchology we are indebted to 

 James Sowerby, who in 1812 commenced, and James De Carle Sowerby, Avho continued 

 the labour of engraving the countless mollusca of the strata of the British Isles. 



It is only in the sixth volume, and towards the end of that volume, that figures of 

 Belemnites occur. They relate to species which had been previously described, some in 

 English and others in foreign works, and include fossils of the Lias, Oolite, and Chalk. 



From the Lias. — B. pistilliformis, t. 589, f. 3. B. penicillatus, t. 590, f. 5, G. B. 

 elongates, t. 590, f. 1. B. acutus, t. 590, f. 7, 8, 10. 



From the Oolites. — B. abbreviates, t. 590, f. 2. B. compressus, t. 590, f. 4 (Scar- 

 borough). (B. ell'pticus, mentioned p. 182. B. (jig as, mentioned p. 182.) 



From the Chalk, Greensand, and Gault. — Belemnites granulates, t. GOO, f. 3, 5. 

 B. lanceolates, t. 600, f. 8, 9. B. attenuates, t. 589, f. 2. B. mmimus,t. 589, f. 1. B. 

 mucronatus, t. 600, f. 1, 2, 4, 6, 7. (Fig. 1 is referred by Sharpe to B. lanceolates, Schl.) 



Belqptera is also noticed, and three species from the Caenozoic series are figured ; one, 

 B- anomala, from Highgate ; the others, B. belcmnitoidea, and B. sepioidea, from France. 



W. Smith, in his works entitled ' Stratigraphical System of Organized Fossils' (1817) 

 and 'Strata identified by Organic Remains' (1816 and following years) notices some of 

 the Belemnites in his large collection, now placed in the British Museum. 



Among the fossils selected for identifying the Upper Chalk he places Belemnites 

 mucronatus; to the Gault, or "Micaceous Brickearth," he assigns Belemnites minimus; 

 and to the Oxford or ' Chinch' Clay, the Belemnite which has been since called Owenii, 

 and has received other designations. The work was never completed. 



In the ' Stratigraphical System' he gives two Belemnites from the Crag, no 

 doubt drifted ; one, a siliceous cast of alveolus from the Chalk. Two Belemnites 

 from the Chalk, one from the Upper Greensand, one from the Gault, one from the 

 Kiinmeridge Clay, one from the Coralline Oolite, two from the Oxford Clay, one from 

 the Kelloways Rock, one from the Fuller's Earth Rock, two from the Inferior Oolite, 

 one from the sand and sandstone below, four from the Marlstone, with which rock 

 the publication ceased. The species are mostly recognisable, except some of those in the 

 Marlstone ; among them may be enumerated the following : 



Chalk ..... Belemnites mucronatus, Sow. 



Greensand .... — plenus? Bktinv. 



Gault ..... — minimus, Sow. 



Kimmeridge Clay ... — excentricus, Blainv. 



Coralline Oolite ... — abbreviatus, Miller.
