CORRIGENDA. 
The first volume (with the exception of the first three chapters) having been printed before the organic remains had been defi- 
nitively compared and named, certain changes in the names of species have taken place. In respect to the ichthyolites, some of 
the new names are announced at page 39, Chapter III. (Sec Vol. II.) 
Page 24 *,for Hoffman read Hofmann. 
42, for Selterophon armatus read Porcellia armata, the 
name Porcellia of L’Kvcille being preserved for 
certain shells approaching to Bellerophon. 
43, for Productus spimsus read P. spimlosus. 
43, for reference to woodcuts, pp. 28 and 30 readoo. 29* 
30 and 30*. 
45, for Lepla-na productoides read Productus produc- 
toides. 
45. The Orlhoceratites subfusifonnis , which we have only 
seen iu fragments buried in the rock, may very pro- 
bably be the same shell as the 0. subpyriformis, 
which we collected in the Devonian strata of 
Voroneje. 
— — 45 el seq.for Priutclika read Prikslia. 
57, for Orthis striaiulus read O. striatula. 
58, for Terebratula plebeia read T. Puscldana ; since we 
now believe this form to be a new species. 
60, for Leptrena armata read L. ( Chonetes ) armata (Bou- 
chard) ; we have since, however, seen reason to 
believe that this species is distinct, and have named 
it Chonetes nana. 
61, for Leptaina caperata read Productus caperatus. 
68 (note). The sketches of certain characteristic ichthy- 
olites announced to be given by Prof. Agassiz in the 
Third Part or Second Volume of this work, have 
not been sent to the Authors : for the structure of 
three genera of Devonian ichthyolites, see PI. II.
