Mr. Wanner thought this might bea Baieropsis. Professor Fon- 
taine admits its doubtful character, and says: 
This is an obscure and very fragmentary specimen. It is too imperfect to show 
anything definite, but may be a small form of Baiera Miinsteriana. It is a small 
form, resembling that plant. 
Mr. Wanner’s note is equally brief: 
The few specimens found are so fragmentary as to present but little more than out- 
lines; yet in general appearance they sufficiently resemble Baieropsis to justify their 
being referred to some species of that genus.
