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
