At p. 29 of my Devonian Monograph I described this species. It seems to have 

 received several names. The Budleigh-Salterton specimens are not numerous, nor in a 

 very complete state of preservation. It has been found once or twice in the same 

 pebble with Sp. Verneuilii and Bh. inaurita. It occurs also in the Devonian Rocks of 

 Brittany.

Spiriferina octoplicata, Dav. Quart. Journ. Geol. Soc, vol. xxvi, p. 79, pi. iv, 



fig. 23, 1869. 



At p. 46 of my Devonian Monograph will be found a full description of this species. 

 In external shape the Budleigh-Salterton specimens resemble the Carboniferous shell so 

 named. It occurs sparingly on the pebbles along with Orthis Monnieri (= 0. Vicaryi, 

 Dav.). In Brittany it is found at Gahard, in a similar sandstone, in company with the 

 same Orthis and Rh. elliptica. 



S. Rhynchonella Winwoodiana, I)av. B. S. Sup., PL XXXVIII, fig. 19. 



Of this species the internal cast of a dorsal valve was discovered by the Rev. II. W. 

 Winwood in a quartzite pebble, in which were likewise present two internal casts of the 

 ventral valve of Orthis Hamoni, Rouault. 



In external shape the dorsal valve is almost circular, measures 9 lines in length by 

 10 in breadth, and is moderately convex ; mesial fold wide and well defined. Surface 

 ornamented by twelve or fourteen strong, wide, simple, angular ribs, of which the four 

 largest occupy the fold, with a deep and wide longitudinal sulcus dividing the middle 

 pair.
