Oligocene. — In the i6th Ann. Rep. of the State Geologist of Indiana, p, 414, 1889, 

 "Area acuminata, Vicksburg Group, Mississippi", is given in a list of specimens in the state 

 museum. There is a recent Area acunmiala Krauss from South Africa, (Siidafrikani- 

 schen Mollusken, p. 14, pi. i, fig. n, 1848). 



Oligocene. — A. oronletisis Gabb, Acad. Nat. Sci., Phila., Journ., 2d. ser., vol. 8, p. 

 346, pi. 44, fig. 21; Dall, Wagner Free Inst. Sci., Trans., vol. 3, pt. 4, p. 658, is from 

 Panama and Costa Rica. Area {Anadara) Petinelli Gabb, Am. Phil. vSoc, Trans., 2d. 

 ser., vol. 15, p. 254, 1873, and Area multilineata Gabb, 1. c, p. 254, from St. Domingo, 

 were not figured. Dall lists them as Oligocene. 



Miocene. — A. maxillata Con., Acad. Nat. Sci. Phila., Journ., vol. 6, p. 264, 1831, 

 from Maryland, was briefly described and was not figured. The specimen was a cast. 



Miocene. — In the Second Bulletin of the Proc. Nat. Institution Promotion Sci., p. 

 181, 1842, Conrad lists A. depletira Conrad together with A. subrostrata from a locality 

 in Marj'land. On p. 183 it is listed from another locality and spelled diplcura. Appar- 

 ently it was never described and doubtless is a synonym of some of Conrad's other 

 species. 



Miocene. — -Among the Galveston deep well fossils Professor Harris found specimens 

 most nearly like the west coast A. labiata and he called them Area labiata Sowerby, 

 var., Bull. Am. Pal., vol. i, no. 3, p. 7, pi. i, figs, i, la, 1895. They were young speci- 

 mens and fragments. 



IVIiddle Tertiary. — Area granulif era Conrad is given in the list of Middle Tertiary 

 fossils in Morton's Synopsis Organic Remains Cretaceous Group, 1834, Appendix, p. 2. 

 Apparently it was not described. 



Tertiary. — A. eosiata Heilprin, Acad. Nat. Sci. Phila., Proc. for 1882, p. 154, was 

 evidently intended for A. eaelata . It is not A. {Limarea) eostata Gray. 



Tertiary. — Area Riiffinif is given in a list of fossils from Me.xico, (Inst. Geol. Mex- 

 ico, Bol., nums. 4, 5, 6, p. 230, 1897). This is probably due to a mistake in copying 

 A. Ruffinif, which is ^w(7wza Ruffini, from an earlier list, (1. c, num. 3, p. 9, 1896J, 

 taken from Heilprin, (Acad. Nat. Sci. Phila., Proc. for 1891, p. 142, 1891). 



Recent. — Area contracta Reeve, Conch. Icon., Corbula no. 27, pi. 4, 1844, was in- 

 tended to be Corbula eontracta Sav. 



This text was written chiefly in 1910 and 191 1. Since then the following new 

 species of Area have been published: 



Area dariensis Brown and Pilsbry, Acad. Nat. Sci, Phila., Proc, vol. 63, p. 362, 

 pi. 22, fig. 10, 191 1, from the Oligocene of the Isthmus of Panama. 



Area gatune}isis Toula, Jahrb. Geol. Reichsanstalt, Wien, vol. 61, p. 493, pi. 30, 

 fig. 4, 191 1, from Gatun, Panama Canal. 



Darbatia simondsi Whitney, Univ. Texas, Bull., no. 184, p. 11, pi. i, fig. 6, 

 191 1, from the Cretaceous of Texas. 



Area {Seap/iarea) limoniea Dall, Smith Misc. Coll., vol. 59, no. 2, p. 2, 1912, 

 from the Pleistocene of the Isthmus of Panama.
