This species has been fully described and illustrated in p. 153 of my 'Jurassic Sup- 

 plement/ Since then a magnificent example, 1 inch and 10 lines in length, by 1 inch 

 and 9 lines in breadth, and 1 inch in depth, has been obtained by Mr. E. Cleminshaw from 

 the Am. Murchisoni-zone at Corton, near Sherborne, Somersetshire ; and of this I have 

 considered it desirable to add a figure in order to show the dimensions to which the 

 shell sometimes attains. 



18. Terebratula maxillata, Sow. Dav., Ool. Mon., PL IX, figs. 1 — 9 ; Appendix to 



Supplements, Vol. V, PL XX, figs. 12, 12 a, b. 



I have fully described this important Jurassic species at p. 50 of my ' Oolitic Mon./ 

 and at p. 121 of the ' Jurassic Supplement.' I there state that this species occurs plenti- 

 fully in the Forest marble, Bradford Clay, Great Oolite, and Cornbrash, and that there are 

 specimens in the Museum of the School of Mines which have been obtained from the 

 Inferior Oolite. Since writing the above a finely preserved and characteristic example of 

 the species has been kindly presented to me by the Rev. F. Smithe, of Churchdown, 

 which he obtained from the Inferior Oolite at llodborough. In England the shell attains 

 its largest size in the Cornbrash. In France M. E. Deslongchamps obtained equally large 

 examples from the Fuller's earth (' Pal. Franc., Brach. Jurassiques,' pi. 104, fig. 1).
