THE BRITISH FOSSIL BRACHIOPODA. 255 



en-Bessin in Normandy, that is to say, in the zone of Am. Parkinsoni. In England it 

 was discovered for the first time by Mr. D. Stephens, and subsequently by Mr. S. S. 

 Buckman, in the same zone at Broadwindsor in Dorsetshire, where the shell appears to 

 be very rare.

V, PI. XVIII, figs. 18, 18 a, b. 



Shell ovate, as long as, or a little longer than wide, broadest anteriorly, sides rounded, 

 indented in front ; dorsal valve convex, at about half its length a narrow concave depres- 

 sion, margined by a rounded elevation or rib, extends to the front j ventral valve rather 

 deeper than the opposite one, with a mesial sinus margined by a rounded rib, which com- 

 mences at a third of the length of the valve and extends to the front ; beak incurved and 

 truncated by a circular foramen. Two specimens measured — 

 Length 7, breadth 8, depth 7 lines. 

 Length 6, breadth 6, depth 6 lines. 



Obs. — This small species seems to be well distinguished from its congeners, and is 

 abundant in the Inferior Oolite (zone of Am. Sowerbyi), at Half-way House (Sherborne) 

 and Bradford Abbas in Dorsetshire, and where it has been collected by Mr. S. S. Buck- 

 man and the Rev. G. F. Whidborne, and forwarded to me for description. It has been 

 also found at Corton-Denham, Somerset. It does not appear to have ever much exceeded 

 the dimensions above stated.

Terebkatula Tawneyi, Whidborne. Quarterly Journal Geol. Soc, vol. xxxix, p. 536, 



pi. xix, fig. 12, 1883. 



Shell marginally almost circular ; dorsal valve deeper and more convex than the 

 opposite one ; beak incurved, foramen circular and completed laterally by two small 

 plates as well as by the umbo of the opposite valves. Surface of both valves covered 

 with fine radiating raised lines, with shorter ones between the principal ones. 

 Length 5, width 4^, depth 3 lines. 



Obs. — This small species is remarkable on account of its striated surface, and was 

 found by the Rev. G. F. Whidborne, F.G.S., in the Inferior Oolite at Dundry near 

 Bristol.
