ATHYRIS. 101 
1889. ATHYRIS concENTERICA, Barrois. Mem. Soc. Géol. Nord, vol. iii, p. 118, 
pl. vu, figs. 3—3 ¢. 
Localities.—From Lummaton about sixty-five specimens are in my Collection, 
three in the Torquay Museum, four in the Woodwardian Museum, one in the 
Bristol Museum, one in the Museum of the Geological Society. From Wolborough 
there are six specimens in Mr. Vicary’s Collection, one in the Museum of Practical 
Geology. 
Remarks.—The Lummaton specimens are all of small size, and must either be 
all young shells or a dwarfed local variety. Their folds are comparatively 
shallow. 
On the other hand, one of Mr. Vicary’s shells is very large, and has a much 
deeper fold than usual.

Russl., p. 511, pl. iv, fig. 17. 
Remarks.—This shell is very rare. I have two doubtful specimens from 
Lummaton. Dr. Davidson’s type specimen came from Hope’s Nose. I have 
nothing to add to his description.

1864. Aruyris Newronrensts, Davidson. Brit. Foss. Brach., vol. iii, pt. 6, p. 19, 
pl. iii, fig. 22. 
Dr. Davidson gives this species in his list of Lummaton fossils. I only know 
two very doubtful specimens from that locality, one in my Collection and one in 
the Museum of Practical Geology.

19, pl. iii, fig. 23. 
Two large fragmentary specimens in my Collection from Lummaton may 
belong to this species. Davidson’s type is in the Lee Collection in the British 
Museum,
