Cypricardites Hainesi.

found while excavating for a well in Fulton, now a part of Cincinnati, 

 at an elevation of fifty or sixty feet above low water-mark. It has 

 been found in the bed of Taylor's creek, just below an old null-dam, 

 above Newport, Kentuck}', at an elevation of about fifty or sixty feet 

 above low water-mark. I found a fragment on a rock up Taylor's 

 creek, above where the Alexandria pike first crosses it, at an elevation 

 of about 150 feet above low water-mark. Good specimens ornament 

 but few cabinets, though a great deal of search has been made for them.

 equal cardinal teeth, anterior one largest and most prominent; lateral 

 teeth short and very remote from the cardinal teeth. 



Cypricardites Hainesi — (S. A. Miller).

umbones sub-angular, with a ridge extending posteriorly and curving 

 toward the base, where it becomes obsolete ; cardinal teeth unknown ; 

 lateral teeth two, one much longer than the other ; muscular impression 

 below the beak anteriorly. 



The cardinal teeth, in the valve, figure 13, being destroyed, as shown 

 by the letter t, the number and character could not be ascertained. 



Surface marked by fine concentric lines. 



Length 1/q inches ; width ^f "^*^'^ '■> gi'eatest depth through the 

 umbones -||^ inch. 



The specific name is given as a compliment to Mrs. M. P. Haines, 

 an earnest and devoted naturalist of Richmond, Indiana, who has col- 

 lected a very fine cabinet and studies to appreciate it.
