 Plate X, figs. 13. 14. 



Fruit small, oval or ovate-rectangular, 8.5 to 9 mm. long, 5.5 to 6 mm. 

 wide; wings rounded and slightly emarginate at apex, about 2 mm. wide at 

 miei'opyle, rather rapidly narrowing downward to less than 1 mm. in width 

 a little below the middle of the altitude, then prolonged and dilated into a 

 concave basal lobe 2 to 2.5 mm. wide, extending downward about 1.5 mm.; 

 nucleus ovate, sharply acuminate at apex, marked by a small depression at 

 the slightly truncate base, and a faint line extending from the micropyle 

 doAvnward a short distance. 



The much greater extension of the wings at the apex and the basal dila- 

 tion distinguish this species from C. irregtdare,-^ a form which it closely re- 

 sembles. 



Locality': Numerous in the fire clay under the Upper Block Coal at 

 Asherville.
