p. 149, pl. x, figs. 3a, 6. 
Remarks.—This species seems very rare. I have never myself found a 
specimen at Lummaton. Davidson’s latest figured specimen is in the Torquay 
Museum. 
In Mr. Vicary’s Collection is a specimen from Wolborough which is smaller 
and narrower than the original example. It shows that the punctations are 
extremely minute and crowded. Its front margin is concave, something in the 
style of Terebratula quadrifida of the Inferior Oolite.

Size.-—The dimensions of two specimens are—length 16 mm., breadth 11 mm., 
depth 8 mm.; and length 16 mm., breadth 16 mm., depth 8 mm. 
Localities.—This is one of the commonest species at Lummaton. There are 
more than 100 specimens in my Collection, seven in the Bristol Museum, twenty 
in the Woodwardian Museum, and six in the British Museum, including Phillips’s 
figured type (fig. 166). 
From Wolborough there are nine specimens in Mr. Vicary’s Collection, two in 
the Museum of Practical Geology, and five in the British Museum.
