jSphe?iozamites robustus, n. sp. Figs. 12-14. 



Frond large, form unknown, pinnules one to four inches in 

 length, ovoid or lanceolate in outline, narrowed and thickened 

 at the base, pointed at summit, margins entire, thickened ; 

 nerves few and strong at base, forking and multiplying above, 

 diverging to all parts of the margins, not converging at 

 summit. 



Quite a number of pinnules, all more or less imperfect, of 

 this remarkable cycad, are contained in the collection brought 

 by Mr. Leggett from Honduras. They vary considerably in 

 form and size, but present characters which are somewhat at 

 variance with those of any other fossil cycads known, though 

 they most resemble those of some species of Sphenozamites. 

 They are distinctly wedge-shaped at base, expanding to an 

 unsymmetrical ovoid or lanceolate outline above with radiate 

 and divergent nerves, which below are few and coarse, above 

 very fine. In the larger pinnules the summit is pointed and 

 in some cases unsym metrically acute. If, as seems probable, 

 the curvature of the pinnules was toward the summit of the 

 frond the general aspect of the plant may have been much like 

 that of Sjphenozamites Geylerianus Zigno (Flor. Fos. Oolitica, 

 vol. ii, p. 107, PL xxxix, figs. 1, 2) only it must have been 

 much larger. Fragments of the lower portions of the pinnules 

 are not unlike some of the specimens of Podozamites lati- 

 pennis figured by Heer (Flor. Fos. Arctica, vol. vi, PL xiv 

 and xv), but the nerves are not parallel with the margins nor 

 do they converge at the summit. 



Among other described fossil cycads none seem to approach 

 so near to the plant before us as the species of /Sphenozamttes 

 with entire pinnules, and here the resemblance is so close that 

 I have felt justified in referring it provisionally to that genus. 



Sphenozamites f grandis, n. sp. 



Pinnules four inches or more in length, oblong or lanceolate, 

 obtuse, narrowed and thickened toward the base, nerves strong, 

 straight, simple or rarely forked, part diverging from the base 

 to the margins, part running parallel to the upper extremity. 



Of this plant we have numerous fragments in the collection, 

 but none of them complete organs. The pinnules were four 

 or five inches in length by an inch in width and are conspicu- 

 ous for their clear and strong nervation, which is radiate from 

 the base. They undoubtedly represent a large cycad, hitherto 

 undescribed, but it will be necessary to have complete pinnules 

 to decide whether it should be referred to Sphenozamites, 

 Otozamites, or Glossozamites. It must have been much like 

 the plant described by Feistmantel (Foss. Flora of the Lower 

 Gondwanas, p. 19, PL xx, figs. 4, 5) under the name of
