The tjrpe-specimen (Stonesfield) of Brongniart's Sphenopteru 

 niacropJiyllus is in the Oxford Museum ; it consists of an imperfectly 

 preserved fragment of what appears to be a bipinnate frond with 

 narrow linear ultimate segments. The fragment figured by Phillips 

 as a ramose plant, and referred with hesitation to Taxites podo- 

 ewrpoides, is also in the Oxford collection. 



Sphenopteris (?) macrophylla is the name given by Brongniart to 

 the Stonesfield specimen ia the Oxford Museum ; he refers the 

 fossil to the ferns with considerable hesitation, and defines the- 

 species as follows : — 



"Poliis pinnatis, rachi piano (alato ?) pinnulis altemis distantibus, 

 maximis (tripollicaribus) insequale pinnatifidis, lobis distantibus- 

 linearibns obtusis uninerviis.'" 



The specimen thus described is, I believe, specifically identical 

 with those represented on Plate X., and with the fossil figured by 

 Phillips as Taxites podoca/rpoides, Brongn. Brongniart, in his de- 

 scription of this species, adds after the name " (ramuH et fructus) ";. 

 he states that it occurs iu Jurassic beds, without giving the locality. 

 The specimen figured by Phillips under the Trench author's 

 name may perhaps he a distinct species. A fragment of a leaf, or 

 leaflet, figured by Buctman in Mui'chison's Geology of Cheltenham, 

 is in all probability an ultimate segment like those represented on 

 Plate X. Saporta refers Brongniart's Sphenopteris macrophyUus
