Sp. Char. — L. fronde sterili partita vel simplice (?) lobis oblongis 
obtusis, margine denticulatis ; nervatione Neuropteridis ; ncrvo primario 
distincto; nervis secundariis snbangulis acutis orientibus, tenuissimis, densis, 
dicliotomis. 
Ohs . — A small fragment of a sterile frond, betraying a membranaceous 
consistence. It shows a primary nerve, tliin, straight, and disappearing 
below the roundish-obtuse apex ; whilst the secondary nerves approaching 
one another are very tender, springing off under acute angles, and dichotomous. 
Their branch lets are mostly lengthened and bent divergingly, crapedodrome 
to small teeth. The probable construction of the fragments conducts to an 
oblong or oval form. It accords very well with the sterile fronds of 
Lygodium , especially to the frond of L. pinnatijidum, Swartz, toothed on the 
borders (see Ettingsliausen, Earnkrauter, PI. CLXX, fig. 10). The similar 
pinnae of Osmunda have mostly untoothed borders, or, if toothed finely, have 
less densely arranged secondary nerves. 
The final determination of the species must, however, be postponed in 
order that the discovery of more perfectly preserved fossils may give satis- 
factory results.
