liemarks. The specimens from the Red Clay-slate of Saltern Cove 
are very fragmentary, but they appear to belong to Steininger's 
species, and to be identical with the examples from Budesheim, as 
determined by Dr. Woodward and Mr. Lee. 
Quenstedt’s species is a Bactrites.

Remarks. This specimen is too imperfect for specific identification. 
It consists of a fragment of a large shell of elliptical form in the 
cross section, and a somewhat rapid rate of tapering. The shell 
is preserved, but it is buried in the rock, to which it adheres 
very tenaciously, and cannot be removed. The cast is perfectly 
smooth. Neither septa nor siphuncle are preserved.
