The rest of the island of Cephalonia as far as we observed it, con-
sists of Scaglia or Apennine limestone. Fossils are rare, but about
a mile north of Argostoli, v^e observed in it many small spiral
univalves, and near the interesting Cyclopian walls of ancient Krani
we found specimens of Nerincea. In crossing the island from Ar-
gostoli to Samo, the stratification of these secondary limestones is
distinctly developed, dipping for several miles about 25° east, and
near the middle of this vast formation we found two beds of a
plicated Ostrea, each about a foot thick.
In Cephalonia and in the range of St. Salvador in the north of
Corfu, the secondary or Apennine limestone is admirably displayed,
having a regular dip to the eastward, and exhibiting an aggregate
thickness of many thousand feet. If a careful observer were to
make a section at these two points across this great formation, he
might establish a series of mineralogical or palaeontological subdi-
visions, and might determine to what extent this vast calcareous
deposit of the Mediterranean basin is equivalent to the secondary
series of Northern Europe.
Description of two apparently new species mentioned in the foregoing
list. By H. E. Strickland, Esq.
Fusus filamentosus^ Strickland. — Small, taper,
volutions about nine, tolerably rounded, with a fine
suture. Ribs twelve on the first volution, very pro-
minent, regular, and rounded; terminating rather
abruptly backwards, and leaving a slight space be-
tween them and the suture. The intervals are deep,
hollowed, and equal to the ribs. Both ribs and in-
tervals are uniformly covered by fine regular thread-
like, striations, of which the first volution has about
twenty-eight, including those which cover the
canal ; the second volution has ten, and the third ^"^"^ fiiamentosus.
six, some of the alternate ones having disappeared. Besides these
striations there are about four much finer ones which cover the
