An examiaation of the fossils from the Horn Sound shows forms 

 identical with, and allied to, both Permian and Carboniferous types. 

 As these occur sometimes in the same hand-specimen, the occurrence is 

 interesting in connexion with the question of the passage between 

 Carboniferous and Permian formations. The fossils are nearly all 

 Brachiopods ; the following species are described as new — -Spiriferina 

 Hoferiana, Prodiictus Wilczeki and P. Spitzbergianus, Aviculopecten 

 Wilczeki. The total number of species and varieties determined is 18.

The prevailing fossils brought from the southern part of the island are 



Productce, S^nriferce, and Streptorhynchi. There is a total of 12 



species, which occur elsewhere in Europe, 5 new sp. and 7 forms 



which are too imperfect to have specific names put to them. 



The new species are, Spirifera striato-paradoxa, S. Wilczeki; Pro- 

 dtcctus Payeri^ described from casts of the interior, P. Weyprechti^ and 

 Rhahdichnites granulosus^ probably the remains of a plant-stem.

 Cerithium lignitarium, Eichwald. [(7. hidentatum and C. ligni-

 Considers that the Miocene species described by Homes as C. ligni- 

 tarium is C, bidentatum, and that the C. Duboisi, Homes, is the true 

 lignitarium. The C. bidentatum is a true Pyrazus, and derived imme- 

 diately from C. gibberosum, Grateloup, of the Oligocene of Gaas, which 

 in its turn is very similar to C. Blainvillei of the U. Calcaire Grossier. 

 From C. bidentatum the recent Asiatic Pyrazi are certainly descended. 

 C. lignitarium is also a Pyrazus^ but rather abnormal, more resembling 

 the Potamides of the Paris Basin, and descending by a curious series 

 of intermediate forms from C. gibberosum, var. /3, Grateloup, of the 

 Oligocene, and C. interruptum, Desh., of the U. Calcaire Grossier.

 which its brilliantly nacreous shell proves it to belong, by its continu-
