Proc. Acad. N. S., Phila., p. 577, '63, (as Codakia). Not 

 multistriatus Tuomey and Holmes. 

 Note. — Dr. Dall questions whether this species is found in the 

 Recent, but our specimens resemble the type closely ex- 

 cept in not having the interior margin crenulated. To 

 the larger, flatter recent shell from the West Indies, char- 

 acterized by less pronounced resting stages, Dr. Dall has 

 given the varietal name of blandus. (B. U. S. Fish Comm., 



1, p. 493, pi. 6, fig. 13, 1901.) 



Distribution. — Hatteras to Cuba, 0-18 fms. Miocene to Re- 

 cent. Gulf coast. — Ft. Barranca and Crooked Isl., Fla. 

 Pliocene : Caloosahatchie and Shell Creek. 

 (CaviJucina) recurrens Dall, Tr. W. I. S., 3, p. 1369, pi. 52, f. 11,

Distribution. — Miocene of Jamaica, Chipola River marl and 

 Oak Grove sands, Fla., and of the Mobile, Ala., No. 2 

 well, Bascom race track, at 124 1 and 1600 feet. 



Note. — This little shell was common in the Mobile region dur- 

 ing Miocene time, as there are twenty-five valves from the 

 Alabama well. They agree perfectly with specimens from 

 Oak Grove.
