1 Some of the Carboniferous species are noticed hereafter under the head of Camarophoria Schlotheimi. 

 The shell identified by Dr. de Koninck with Professor Phillips's Terebratula rhomboidea appears to he a 

 Cametrophoria : I have seen in Mr. T. Davidson's collection, specimens which closely resemble C. Schlotheimi. 

 Perhaps Kutorga's Spirifer triplicatus is of the same genus ; and from what M. de Verneuil states (Geol. 

 Buss., vol. ii, p. 396), the Pentamerus plicatus and P. sella of this author are evidently Camarophorias. 



2 I regret being unacquainted with De Vemeuil's Terebratula Geinitziana : perhaps this allusion will be 

 the means of calling attention to its generic position. 



^ Schlotheim, having included under the name Terebratulites lacunosus, three different species belonging 

 to three different formations, the Silurian, Permian, and Jurassic, M. von Buch was induced to name those 

 respectively belonging to the first two formations, Terebratula borealis, and T. Schlotheimi, leaving the 

 Schlotheimian name for the Jurassic species.
