Dantzic, residing at Bristol, and charged with the custody of the Museum of the Institution 

 there, ' Observations on Belemnites/ in which twelve species were named, described, 

 and figured. Notwithstanding some errors, which may be partly typographical (as when 

 Plot, who wrote in 1077, is represented as communicating a paper to the 'Phil. Trans.' 

 in 17G4, the true author being Joshua Piatt), this is a treatise of much value, and it 

 made a first and important step in the right direction. He describes and figures the 

 following species, mostly named by himself. 



1. Belemnites abbreviatus. PI. VII, figs. 9, 10. Prom Weymouth and Dundry. Inferior 



Oolite. The specimen figured is in the Museum at Bristol, and appears really 

 to have been derived from the Coralline Oolite, in which the snecies is common. 

 It has not been found in the Inferior Oolite at Dundry or elsewhere. The 

 description is inadequate, and other species have since been ranked under this 

 name. 



2. Belemnites adnneatns. PI. VIII, figs. 0, 7, 8. Prom Weymouth and Lyme, in Lias. 



The former locality is incorrect. It is difficult to identify this species, though 

 specimens occur in Upper Lias which somewhat resemble this figure of Miller. 



3. Belemnites sulcatus. PI. VIII, figs. 3, 4, 5. Prom Dundry, near Oxford. Inferior 



Oolite. There is more than typographical confusion here. Pigs. 3 and 4 

 are taken from Dundry specimens, and belong to a species found in the Inferior 

 Oolite. Pig. 5 is from an Oxford specimen of a different type, out of the clay 

 of that name. Mistakes in regard to this name are very common. 



4. Belemnites elongalu*. PL VII, figs. 0, 7, 8. Prom Lyme, in Lias. Imperfectly 



defined, so that different species have been since called by this name. 



5. Belemnites longissimus. PI. VIII. figs. 1, 2. Prom Lyme, in Lias. 



0. Belemnites acutus. PI. VIII, fig. 9. No locality ; l but reference is made with doubt 

 to Lhwyd, fig. 1GS3, which represents a fossil from Merston, in Northampton- 

 shire. Much confusion in regard to the application of this name by Blainville 

 and later writers. 



7. Belemnites tripartitus, Schlottheim. PI. VIII, figs. 10, 11, 12, 13. No locality 



given. Not easily identified, among several cognate forms. 



8. Belemnites ellvpticus. PI. VIII, figs. 14, 15, 10, 17. From Dundry. Inferior Oolite. 



By many writers identified with B. giganteus. 



9. Belemnites electrinus. PI. VIII, figs. IS, 19, 20, 21. Salisbury, Brighton, Lewes, 



Chalk. Some foreign localities are given in error, the Baltic species being 

 different from that of Maestricht. 



10. Belemnites fusifonnis. PI. VIII, fig. 22; PI. IX, figs. 5—7. Stonesfield. 



11. Belemnites minimus. PI. IX, fig. 0. Polkstone, Ringmcr, &c. Gault.
