i899 C. UPTON— BRACHIOPODA I25 



indistinct ; margin almost straight, with a shghtly elevated 

 front, which in some specimens becomes somewhat 

 angular; shell smooth, growth lines faint; loop short. 

 Length 23 mm., width 20 mm., height 15 mm. 



Terebrattila sphcrroidalis, Sow., has not hitherto been 

 recorded from any Cottesvvold locaHty. In Somerset and 

 Dorset, and in Calvados it occurs abundantly in the upper 

 beds of the Inferior Oolite, attaining its largest dimensions 

 in the neighbourhood of Bayeux. The type came from 

 Dundry Hill, where however it is scarce and ill-developed. 



On Selsley Hill, near Stroud, there is a bed of fine- 

 grained, non-oolitic limestone about two feet in thickness 

 over-lying, or possibly constituting the uppermost bed of 

 the Upper Trig07iia-Gn\ which yields a form approach- 

 ing closely to T. sphcBroidalis. The shells are slightly 

 elongate approaching T. decipiens, but most nearly re- 

 sembling the shell usually called T. sphcBroidalis from 

 Castle Cary. At North Nibley a somewhat similar, but 

 usually more elongate shell occurs ; and I have a 

 couple of specimens approaching the Nibley forms which 

 I found in a quarry on Wickeridge Hill near the Slad 

 Village. This is the most northerly spot at which 

 I have yet found them. This fossil differs from 

 T. spharoidalis in being much narrower in the neigh- 

 bourhood of the hinge, in the greater projection of the 

 beak which has a somewhat tubular character, and in 

 the more acute angle formed by the junction of the 

 valves. I therefore distinguish it by the name sub- 

 sphcsroidalis.
