JURASSIC AND TRIASSIC BRACHIOPODA. 149 



Abbotsbury, near Lyme Regis in Dorsetshire, associated with Wald. lampas, W. Dorset- 

 iensis, and Bh. pinguis, var. pectunculoides. The shells are of an ochreous-brown colour, 

 due to the matrix, and occur chiefly in the condition of internal casts. T. subsella some- 

 times so much resembles Ter. sella from the Neocomian formation, that in 1846 it was 

 mistaken for that species by Mr. Leymerie, who described and named the shell under 

 description. 



It varies chiefly in the degree of approximation and projection of its two rounded 

 folds and in the depth of the sinus which separates them. The shell has been most 

 carefully described and illustrated by Mr. de Loriol from specimens derived from the 

 Kimmeridge Clay of the Boulonnais, where I found it for the first time upwards of 

 thirty years ago. It was subsequently met with by Mr. Pellat at different levels in the 

 same formation, the most typical examples occurring in the zone characterised by an 

 immense abundance of Ostrea virgula. It occurs likewise lower down in the upper beds 

 of the u Etage Sequanien," from which horizon our British specimens are apparently 

 derived. Mr. de Loriol mentions its occurrence in a number of other places, such as at 

 Cirey, Rachecourt, Bure, Nully, in the zone of Cgprina Brongniarti (Etage Portlandien) ; 

 Pancey-Rupt, Blaise, zone of Am. caletanus (Etage Virgulien) ; Harnieville, Blaize, 

 zone of Am. orthocera, Pterocerian zone ; Champcourt, Harmeville ; 2nd zone of 

 T. humeralis ; Soncourt, 1st zone of T. humeralis, Etage Sequanien. Oppel (Die Jura) 

 states that it occurs in the zone of Pterocera oceana, at Lindener and Tonnies Berg, near 

 Hanover, also in the Grey Marl of Arensburg, near Biickeling, east of Minden, and in 

 the Kimmeridge Clay of Havre and Honfleur, and that it abounds in the zone of 

 Pterocera oceana of Tonnere, Yonne. 



Terebratula globata, Sow. Sup., PI. XVII, fig. 3 (see p. 135). 



Specimens of this typical form of T. globata have been found at Whatley Church, near 

 Frome, and at Burton Station in the Fuller's Earth Rock, by Mr. J. F. Walker, along 

 with Wald. bullata. It is probable that Sowerby's type from Nunney, near Frome, came 

 from this rock. Another variety of Ter. globata occurs in the Inferior Oolite of Leck- 

 hampton Hill, Gloucestershire. It differs from the type-specimens in being more tumid, 

 the valves being convex, and the plications not extending so far up the valves ; the outline 

 of the shell is rounder. The beak is short, incurved, the foramen large, and the hinge- 

 line straighter. It might be called T. globata, var. tumida.
