57. Terebratula carnea, Sow. Dav., Cret. Mon., PI. VIII, figs. 1 — 5. 



Some internal casts in flint nodules of this species have been picked up at Cruden, in 

 Aberdeenshire (see Davidson, " Scottish Cret. Brach.," 'The Geologist,' December, 1862, 

 vol. v, p. 446, pi. xxiv, fig. 14).

We figure a large specimen from the " Folkstone beds " near Shanklin.

Spec. Char. Shell oblong-ovate, widest about the middle, deepest towards the 

 posterior portion of the shell. Ventral valve uniformly convex, without sinus ; beak 

 incurved, truncated by a moderate- sized foramen, separated from the hinge-line by a 

 small deltidium ; beak-ridges well defined. Dorsal valve convex, depressed at the sides, 

 most convex along the middle, and elevated in front. Surface smooth, marked by 

 concentric lines of growth. Loop elongated, extremity of reflected portion angular. 

 Length 10, width 7, depth 4| lines. 

 05s. This species was described and figured for the first time by Mr. E. R. Lankester 

 in 1863, under the erroneous designation of Terebratula Moutoniana, d'Orb., and was 

 subsequently shown by Dr. U. Schloenbach and Mr. Meyer to be distinguishable from 

 T. Moutoniana by its lengthened loop, and from Waldheimia celtica, Morris, by the com- 

 paratively greater breadth of its valves and by the curvature of the margin, which in W. 

 Celtica is always nearly straight.
