MAGELLANIA. 93 
Localities.—I have one or perhaps two specimens from Lummaton. 
Remarks.—This shell gives me some perplexity. It differs from all the other 
specimens of Terebratuloid shells which I have found in the same localities except 
C. virgo by having low rounded ribs, and possibly by the high position and small 
size of its foramen. From C. virgo, however, it seems to be distinguished by the 
much greater fineness and irregular arrangement of its puncta, while its foramen 
seems smaller, higher, and different in shape. | 
I have only one specimen which definitely shows these characters. It is 
therefore not safe to give it a name, as it may prove to be an accidental variety of 
some other shell. A second specimen, which is somewhat similar, is curiously 
marked with very minute ridges arching inwards, but not quite following the 
marginal curves.

Localities —From Lummaton there are about fifty specimens in my Collection, 
thirteen in the Woodwardian Museum, eleven in the British Museum, and two in 
the Bristol Museum. From Wolborough there isa single specimen in Mr. Vicary’s 
Collection, and two in the Museum of Practical Geology. 
Size.—One of my specimens considerably exceeds the dimensions given by 
Davidson, being 19 mm. long, 18 mm. broad, and 8 mm. deep. 
Remarks.—It seems to me most probable that Terebratula ? mexqualis, 
F. A. Rémer, is only a distorted form of this species. It very nearly resembles 
one of my specimens.
