12 PEOCEEDINGS OP THE NATIONAL MUSEUM vol.72 



Cretaceous of Australia as G erato'plyyTluTn australe, but these are 

 hardly convincing enough to have any weight.^ This same author 

 identified equally indefinite leaf fragments and stem nodes from the 

 Miocene of Leoben and Schonegg in Styria as G eratophyllum ter- 

 tiarium.^ Saporta described some stem impressions with verticillate 

 leaves from the Aquitanian of France as GeratophyUum aqybaticumy 

 Certain spiny fruits from the lower Eocene of Tennessee have been 

 described by the present writer {G eratophyllwni incertmn Berry MS.) 

 which if actually related to Geratophylluvv are by far the oldest 

 record of the genus. 



During the Pleistocene numerous occurrences of fruits not to be 

 distinguished from the variations seen in the fruits of the existing 

 plant have been recorded from Canada and the United States, Eng- 

 land, and Germany. 



Occurrence. — Coal prospect 4 miles southeast of Morgan Eanch 

 and 15 miles west of Hawthorne, Mineral County, Nev. 



Gotypes.—C2Lt. No. 37304, U.S.N.M. 



Family NYMPHAEACEAE ? 

 Genus CASTALIA? Salisbury 



CASTALIA7 sp. 



Plate 1, fig. 1 



Small elliptical, equilateral, and apparently somewhat compressed 

 seeds with a dense coat, about 3.25 millimeters long and 2.5 milli- 

 meters in width. There are several of these seeds in the collection. 

 Their preservation does not disclose features sufficient to substantiate 

 their supposed affinity, and they are therefore tentatively identified. 



The genus Gastalia has about 30 existing species of large aquatic 

 herbs, widely distributed in fresh water but absent on the present 

 Pacific slope, although present in eastern Asia. It is present in the 

 former region in the earlier Tertiary but has not been detected in the 

 Miocene or later epochs. 



Occurrence. — Coal prospect 4 miles southeast of Morgan Ranch 

 and 15 miles west of Hawthorne, Mineral County, Nev. (Cat. No. 

 87305, U.S.N.M.)
