Bull. 37, U. S. N. M., p. 48, pi. 6, f. 12, pi. 42, f. 4, '89. 

 Distribution. — Hatteras to Barbados, 3-100 fms. Upper Mio- 

 cene to Recent. Gulf coast. — Recent : West Fla., 30 fms. 

 Pliocene : Charlotte Harbor, Fla. Upper Miocene : Gal- 

 veston well at 2158-2920 feet. (Harris). 

 (Cuna) dalli Vanatta. Proc. Acad. Nat. Sci. Phila., 55, p. 759, f- 



3, 1903- 



Distribution. — Indian Pass, West Fla. (type locality). Pleis- 

 tocene shells resembling this species were found in the 

 New Orleans Gj'mnasium well at 1200 feet. 



Note.' — Recent species of Cuna were thought to be exclusively 

 Australian and Japanese. The only known American 

 species was Claibornian Eocene. Vanatta' s discovery 

 shows that the genus has existed sparsely in the Gulf of 

 Mexico from early Tertiar}- to Recent time. 



Genus CRASSINELLA Guppy 

 galvestonensis Harris, Bull. Am. Pal. l, No. 3, p. 8, pi. i, f. 2a- 

 b, 1895, {diS Eriphyla); Dall, Tr. W. I. S., 3, p. 1478, pi. 

 49, f. 14, 1903- 

 Distribution. — Recent : Galveston. Miocene : Md., Va. ; Sea 

 Isle City, N. J., well at 785 feet ; Galveston well at 2600 

 feet. (Tj'pe locality). 

 Note. — Professor Harris remarked in his description, "The 

 new Eriphyla will probably' be found Recent on the Gulf 

 shore. ' ' Comparisons of shells from the beach with the 

 deep well type now prove this to be the case. The species 

 has continued on unchanged and lived in the same locality 

 from Upper Miocene time.
