200 APPENDIX TO THE SUPPLEMENTS TO 



12. Terebratula linguifera, S. S. Buckman, MS. Dav., Appendix to Supplements, 



Vol. V, PI. XIX, figs. 1, 1 a, b. 



Shell obscurely subpentagonal, longer than wide, broadest about the middle. Dorsal 

 valve with a produced linguiform, flattened, or biplicated mesial fold, commencing to rise at 

 about two thirds of the length of the shell and extending to the front. Ventral valve 

 rather more convex and deeper than the dorsal one, with a flattened mesial sinus 

 commencing at about two thirds of the length of the valve ; beak incurved and truncated 

 by a circular foramen. 



Length 1^ inch, breadth \\ inch, depth 10 lines. 



Obs. — I believe this to be the same species as the one referred to a variety of T. 

 Kleinii at page 123, and PI. XVII, fig. 9 of my 'Jurassic Supplement/ but it is 

 questionable whether it is a variety of Lamarck's species. Mr. S. S. Buckman when 

 forwarding the specimen to me for description gave it the name linguifera on account 

 of the shape of its mesial fold. It occurs in the Fuller's earth rock at Haydon, 

 Dorset. The first Dorsetshire specimen was discovered by Mr. E. Cleminshaw. 



13. Terebratula provincialis, E. Bed. {?) Dav., Appendix to Supplements, Vol. V,

Club, vol. iv, p. 25, 1872. 



Mr. S. S. Buckman thinks he can refer to Deslongchamps' species a specimen he 

 obtained from the Inferior Oolite, Am. Murchisoni zone, Hawthorn Down, near Corton 

 Denham, Somersetshire, and believes that this species is to Ter. curvifrons what Wald. 

 Meriani is to Wald. carinata. He adds, in his description, that the very much incurved 

 beak is its distinguishing feature. It is also deeper and narrower in proportion than T. 

 curvifrons, but the sinus in the smaller valve is not so deep. It would be very desirable 

 that more specimens should be collected so as to confirm the identification given here on 

 Mr. S. S. Buckman's authority. The Dorset specimen which Mr. S. S. Buckman identifies 

 with T. provincialis is certainly very like the figure Deslongchamps gives of the last-named 

 shell in pi. lxxxiv, fig. 4, of his ' Brachiopodes Jurassiques.'
