DESCRIPTION OF SILURIAN FOSSILS FROM THE RHENISH PROVINCES, 

 BY J. DE CARLE SOWERBY, F.L.S. 



PLATE XXXVIII. 



Fig. 1 and 2. Pterinea lamellosa (Goldfuss, 136. t. 120. fig. 1 and 2). Goldfuss has described and 

 figured only one valve of this species ; the other valve is flat, and (as usual in shells of this family) the 

 ears in it are not separated by a sinus from the body of the shell. Loc. Kemmenau (fig. 1), Wipper- 

 thal (fig. 2). 



Fig. 3. Pterinea costata (Goldfuss, 137. t. 120. fig. 4). A remarkably convex species; the speci- 

 men shown in this figure is larger than the one figured by Goldfuss. Loc. Kemmenau near Ems. 



Fig. 4. Atrypa curvata (Anom. Terebratulites curvatus, Schl. Pet. Nacht. 1. 68. tab. 19. f. 2). This 

 appears to be the same as described by Schlotheim, but it is difficult to determine from such an imper- 

 fect cast. Loc. District of the Eifel. 



Fig. 5. Spirifer speciosus (Anom. Terebratulites speciosus, Schlot. Pet. Nacht. 1. 66. tab. 16. fig. 1). 

 Trigonotreta speciosus, Kcenig, Icon. Foss. Sectiles, 3. tab. 6. fig. 71., Bronn. Letheea Geog. tab. 2. fig. 1.5. 

 Spirifer macropterus, var. Goldfuss, MSS.? There is no character that I am aware of to distinguish 

 this from the S. speciosus of Schlotheim, but as the internal structure exhibited by the cast is totally dif- 

 ferent from that of Sp. micropterus, I quote Goldfuss with doubt. Loc. Priim. 



Fig. 6. Spirifer micropterus, Goldf. {Hysterolites hystericus, Schlot. Pet. 1. 1. 29. fig. 1). This shell 

 with its imbricated surface on the three acute lobes of the internal cast produced by two septa diverging 

 from the prominent beak, is well figured by Schlotheim, and it is perfectly distinct from Sp. speciosus, 

 which wants the internal septa ; nevertheless Goldfuss has considered them both to be varieties of his
