This species, which is common in the Raton 

 formation and in the upper part of the Wilcox 

 group, is much more common west of the Missis- 

 sippi than east of it. A specimen from Loui- 

 siana is figured in the present paper. 



Occurrence: Goss pit, half a mile east of 

 Mansfield, De Soto Parish, La.; collected by 

 O. M. Ball.

This well-marked species, which is abundant 

 in the Raton formation in Colorado and New 

 Mexico, appears to range from the bottom to 

 the top of the Wilcox group in the embayment 

 region. It has not heretofore been found in 

 that region west of the Mississippi but proves 

 to be not uncommon in Louisiana.

Plate XI, figure 1. 



Leaves orbicular-ovate, about as wide as long, 

 with a wide truncate base and a broadly and 

 shortly pointed apex. Margins entire. Texture 

 thin. Length about 10 centimeters; maximum 

 width, below the middle, about 10 centimeters. 

 Petiole missing, but from the character of the 

 base it must have been of considerable length 

 and expanded where it joined the lamina; the 

 joint was at an angle with the plane of the 

 lamina. There are 7 primaries from the widely 

 expanded apex of the petiole at the extreme 

 base of the leaf. These diverge at acute regu- 

 larly spaced angles; all are curved, and the 

 midrib is slightly, if at all, stouter than the 

 lateral primaries. It is longer, however, and 

 at about one-third of its distance to the apex 

 it gives off, at acute angles, a pair of opposite 

 secondaries, which sweep upward and are camp- 

 todrome in the tip of the leaf. The lateral pri- 

 maries are. all stout and prominent and decrease 

 in length from above downward. The basal, 

 shortest, and straightest pair form angles of 

 about 70° with the midrib; they give off on the 

 outside three or four regularly spaced second- 

 aries, which are camptodrome close to the 

 margin; the tip joins the tip of the basal sec- 

 ondary of the primary next above by a simple 

 camptodrome arch close to the margin. The 

 second pair of primaries form angles of about 

 50° with the midrib; they are longer and 

 slightly stouter than the basal pair and slightly 

 more curved, but less so than the third pair 

 of primaries; they give off on the outside two 

 to four regularly spaced stout secondaries, 

 which are camptodrome close to the margin; 

 their tip joins a simple camptodrome tertiary 

 from the lowest secondary of the third primary 

 by a simple camptodrome curve close to the 

 margin. The third pair of primaries form 

 angles of about 25° with the midrib; they are 

 more curved than the others and give off on 

 the outside four or five regularly spaced sec- 

 ondaries, which are simply camptodrome close 

 to the margins and the basal one of which may 

 have the caliber and appearance of a dichoto- 

 mous fork of the primary, as in the left side 

 of the leaf figured; the tip of the third primary
