BRITISH DEVONIAN BRACHIOPODA. 47 



give a figure. Some well-preserved internal casts of both valves have also been found by 

 Mr. Champernowne, east of Mudstone Bay, near North End. The beds there dip north, 

 and are nearly vertical at the point where this fossil occurs. 



40. Rhynchonella acuminata, var. platiloba, Sow. Dav., Dev. Sup., PI. II, 



fig. 20. 



Some specimens of this variety of Rhynchonella acuminata, undistinguishable from 

 similar Carboniferous specimens, have been found by Mr. Whidborne at Lummaton, near 

 Torquay. 



41. Rhynchonella triloba, Phillijis. Dav., Dev. Mon., PI. XII, figs. 1 — 7 ; and Dev. 



Sup., PI. II, fig. 21. 



Some very much flattened specimens, which I refer with some uncertainty to Rh. 

 triloba, have been found bv Mr. Whidborne in the Middle Devonian at Lummaton. 



42. Rhynchonella Leei, Dav. Dev. Sup., PI. II, figs. 15, 15a. 



Shell transversely oval, broadly rounded anteriorly, obtusely acuminated poste- 

 riorly ; dorsal valve very convex, without fold or sinus, deepest about the middle ; 

 ventral rather less convex than the opposite valve; no sinus; beak small, incurved. 

 Surface of valves marked by radiating ribs, which extend to only about two thirds of the 

 length of the valve ; the anterior third ornamented with about eight short rounded ribs, 

 with concave interspaces of about equal breadth. Interior not known. 

 Length flinches, breadth If inches, depth 1 inch. 



Ohs. — This is a very remarkable shell, and, as far as I am aware, specifically distinct 

 from its Devonian congeners. One specimen, somewhat decorticated, was found by Mr. 

 G. E. Whidborne in the Middle Devonian at Lummaton, near Torquay. 



I have much pleasure in naming this species after Mr. John Edward Lee, F.G.S., to 

 whom I am indebted for much kind help. Mr. Lee indeed has been one of our best 

 workers among the Devonian rocks in the neighbourhood of Torquay, and has collected 

 steadily for more than forty years both in England and upon the Continent ; and this has 

 been most important, as it has enabled him to bring out the sequences of strata in a way that 

 would have been otherwise nearly impossible in so disturbed a locality as that of Torquay.
