Feistmantelia " VIRGINICA Fontaine n. sp. 

 PI. CVII, Fig. .3. 



This plant occurs in four well-marked specimens. The character- 

 istic cigar-shaped convexities are very distinct. There is no verj' good 

 feature which may serve to determine, as distinct species, the specimens 

 of this peculiar fossil, which have been found at widely separated locaUties. 

 The specific name virginica is given to the plant from this locality to 

 indicate the place of occurrence rather than its necessary specific indepen- 

 dence. 



PL CVII, Fig. 3, gives one of the most distinct of the specimens found. 

 The four specimens in the collection are not to be taken as a measure of 

 the abundance of the fossil at Cockpit Point, for a number of others could 

 have been obtained. 



« The genus Feistmantelia was named by me in my paper on tlie Cretaceous formation of the Black 

 Hills (Nineteenth Ann. Rep. U. S. Geol. Surv., Pt. II, 1899, p. 693 ), founded on specimens collected by Professor 

 Jenney in the Hay Creek coal field. In an extended note on pages 694-696 I set forth the grounds for thus 

 treating it. Professor Fontaine was with me when I collected the specimens at Cockpit Point on Juh' 27, 

 1894, and we discussed these objects together. In his description of the Hay Creek specimens, to which he gave 

 no systematic name, he mentions those from Cockpit Point, but neither of us at that time ventured to assign 

 to them a specific name. I did, however, name the Hay Creek form Feistmantelia ohlonga, and the form 

 figured by Feistmantel in the flora of Koch, F. fusiformis. We now have a third species, and the form from 

 the Cheyenne sandstone of Kansas, mentioned in my note, will probably be a fourth, when the time arrives 

 for treating it. — L. F. W.
