In addition to the above, it may be well to mention the following found in 

 this locality, but so far not identified with certainty. 



(a.) Monticulipora. — Several specimens referable to two species of this genus. 



(6.) Crinoidal stems. — Probably those of the genus Ileterocrinus. 



((i) Modiolopsis. — Showing both concentric lines of growth and numerous 

 radiating lines proceeding from the anterior extremity of the shell, and extend- 

 ing to its margin, allied in some respects to M. canceUatiis of Walcott, but speci- 

 fically distinct from it. Only two specimens of this shell have been found. 

 When more are obtained it may prove to be a new species. 



(e.) Pleurotomaria. — Allied to P subconica, (small sp.) 



(/.) Lepcrdiiia. — Probably L. ci/lindrica, Hall.
