 Terebratula ; since then Mr. J. F. Walker has discovered that it has a long loop, and

1 Three varieties of Waldheimia obovata occur, viz., typical, narrow, and rhomboidal. Since this list 

 was published T. ballata has been found to be a Waldheimia, and W. Margarita, Oppel, has been found 

 in the Coral-rag of Yorkshire.
