118 Raymond — Upper Devonian Fauna with Clymenia. 



Goniatite, like G. (Prolobites) delphinus, 

 Gheiloceras, 2 species, 



Clymenia * somewhat like C. annulata Mtinst., 

 Clymenia sp., 



Loxopteria, near L. Icevis Freeh, 

 Loxopteria, near L. dispar. Sandb., 

 Mecynodus, or Goniop/wra sp., 

 Leiorhynchus sp., 

 Camarotoechia sp., 



Spirifer Yerneuili Murch. = 8. disjunctus Sowerby, 

 Athyris sp. 



In addition to these, the collection contains fragments of 

 another species of Clymenia, a small gastropod, a JYucida and 

 Spirifer pinonensis Meek. 



In commenting on this faunnle, Prof. Holzapfel states that 

 the mode of preservation is exactly like that of some fossils 



Figure 1. — An exfoliated specimen, natural size, of Clymenia (Platycly- 

 menia) americana, in which the inner whorls are not preserved. Two 

 views of a fragment of another specimen, twice natural size, to show posi- 

 tion of the siphon and form of the suture line.

in the Nehden shales, and that, except for the presence of 

 Clymenia, which gives the fauna more the aspect of that 

 of the Clymenia limestone, the composition of the fauna is 

 analogous to that of the JN r ehden shales. 



*This species of Clymenia is abundant in zones 1, 2, and 4, and may be 

 readily recognized by its broad-backed, compressed and ribbed whorls. The 

 suture is simple, as is shown by the accompanying figures. The name 

 Clymenia (Platyclymenia) americana is here proposed for this species.
