Note. — The species of the two genera figured on this plate, especially Haliolis, are exclu- 

 sively inhabitants of shallow water, and this circunistauce must be taken into consideration by 

 geologists in correlating the strata in which they occur with those probably synchrouous but 

 deposited in deeper water in other localities.
