ably like, if not identical with that described by Schenk (Flora 

 der Grenzschicten, p. 168, PL XL, figs. 2, 3) under the name of 

 Pterophyllum Braunsii. The pinnules were attached by the 

 entire base, are an inch in width by two and a half inches in 

 length, the summit is obliquely rounded, the nervation fine, 

 parallel and simple, sometimes dotted as shown in Schenk's 

 figure. 



A nearly related plant to this is Pt. princeps Oldham and 

 Morris (Fossil Flora of the Pajamahal Series, p. 23, PL x-xiii), 

 but our material is too imperfect for the determination of spe- 

 cific identity or difference. 



Dioonites longifollus f Emmons. 



An imperfectly preserved fragment from the middle of a 

 frond is all we have of a plant that if not identical with must 

 have been very closely allied to that described by Emmons 

 (Amer. GeoL, Part VI, p. 116, fig. 83) from the Upper Triassic 

 strata of North Carolina. 



Dioonites Carnallianusf Goepp. 



This plant is imperfectly shown in the collection made by 

 Mr. Leggett, but is plainly distinct from any other with which 

 it is associated. It evidently belongs to a group of cycads 

 which form a marked feature in the Phsetic flora and of which 

 Pterojphyllum Garnallianum of Goeppert may be taken as a 

 type. In this group the fronds are broad, the pinnules very 

 long and narrow, attached to the rachis by the entire bases, 

 which are sometimes slightly decurrent, but never expanded 

 upward nor connate ; the nerves are sharply defined, but fine, 

 simple and parallel. 



More material will be required before the identity of the 

 Honduras plant with that to which it is provisionally referred 

 can be asserted. It is, however, a distinct element in the San 

 Juancito flora and deserves mention from its relationship with 

 the group of Rhaetic cycads with which I have compared it. 



Nilssonia polymorpha Nathorst. 



Only a few fragments of this plant are contained in the col- 

 lection made by Mr. Leggett, but these are quite sufficient to 

 show its distinctness from any other with which it is associated 

 and to determine its generic relations. Whether the segments 

 of the frond were united, as is usual in JSf. polymorpha, can 

 only be determined from other collections, but this is not indi- 

 cated by the specimens before us ; the pinnules being entirely 

 distinct and separated. 



Fragments of the species of Anomozamites found with this 

 might at first sight be confounded with it, but in these the
