ANOMIA. 133 
from its likeness to the engraving referred to. Thanks to 
Lovén, Middendorff, and Nillson, our knowledge of the shell- 
fauna of the North of Europe is tolerably accurate, and we may 
fairly presume that the supposed analogue was either septigera 
or cranium: the latter is still in the collection. Although in 
the twelfth edition of the ‘Systema’ the original synonymy and 
description was reproduced, with the mere substitution of 
“in M. Norvegico” for the previous “ fossilis,’” some writers 
upon recent conchology have strangely essayed to identify it 
with the 7’. vitrea of Born, a Southern shell wholly destitute of 
the folds invariably assigned to the species in question. No 
smooth triplicated form, indeed, is recorded in the Monograph 
of recent Terebratule by the late G. B. Sowerby. Gmelin, 
Schréter, Lamarck, and the majority of conchologists, treat it 
as a fossil. 
Aronia angulata. 
One fossil alone in the Linnean collection answers to the 
description of this species. It is contained in the box so 
marked in our author’s cabinet, and is, as determined by 
Messrs. Sharpe, Davidson, Salter, and 8. Wood, the Tere- 
bratula eaxcavata of Phillips (Geol. York, vol. ii. pl. 12, f. 24), a 
shell obtained in the Mountain Limestone in the Isle of Man. 
Mr. D. Sharpe has communicated likewise the following parti- 
culars :—‘“ This species of Terebratula varies both in general 
shape and in the number of plaits, but the remarkable com- 
pression or excavation on the sides renders it easy to be recog- 
nised. The 7. angulata of the ‘ Mineral Conchology’ (504, fig. 4) 
exhibits essential differences. 'The Linnean species appears to 
be confined to the Mountain Limestone, and is not a very com- 
mon shell.” The cited figure bears a general resemblance to 
the typical form. 
Anomta Hysterita. 
“The tray marked for this species in the Linnean cabinet 
contains the internal casts of two distinct species. ‘That which
