The species contained in the foregoing list are mainly from 
the top of the Temblor, or the horizon of Zone C, and were 
collected by the writer or by Mr. John Barker as before stated. 
In addition to the above species there are many remains of 
- rays, skates, sword-fish, and other marine fishes and animals. 
Vertebrae and other bones of whales, and the jaws, teeth, and 
ribs of marine mammals are occasionally found. Teeth of sea 
lions and of Desmostylus have also been found among the 
fossils of Zone C. 
According to Blake’s statement, the species described by 
Agassiz were, with perhaps two exceptions, obtained from a 
lower horizon on Poso Creek; but as far as known to the 
writer, the most prolific beds are at the upper limit of marine 
shells. The beds of this horizon are probably the most per-
