Merriam. — New Marine Reptile.

this group is not at present entirely clear. It will not improbably 

 be found to represent an independent ordinal group among the 

 synapsidan forms. It is hoped that the true position of this 

 genus may be more clearly defined by the discovery of more com- 

 plete specimens at the same horizon as that from which this mate- 

 rial was obtained.
