This genus, with two or three species and several varieties, is very 
numerously represented in India, in the upper portion of the Gondwana 
System (generally speaking Jurassic). Prom Australia Mr. Tenison Woods 
described one species.

Sq). Char . — Proud pinnate, long linear, gradually tapering to the apex ; 
pinnae rather long, narrow, slightly oblique, alternate, separate, but very 
close, rounded and curved, somewhat falcate, ending in quite an acute apex 
at the upper edge ; base rounded or articulate above, obliquely inserted, 
leaving when detached a series of oblique alternate elongate depressions on 
the racliis ; veins distinct from their origin and parallel to the apex, from 
four to six in number, all well marked and conspicuous ; length of longest 
pinnae 12 to 15, breadth 1|- to 2 mm. 
Locality and Horizon . — Very common in the plant formation of Hose- 
wood, near Rockhampton, where it is associated with a Sequoia (?), a large 
Lquisetum, some ferns and Vertehraria.

Ohs. — This is the diagnosis which Brongniart gave from specimens 
from Raniganj, Bengal, in India. The species was Zcugophyllites calamoides, 
Bgt, 
It was often insisted on that the Zeugophyllitcs of India was identical 
with Schiz one ura , from the Indian Gondwana system, and at first I was 
inclined to believe so. But when I saw that also, in his “ Tableaux des 
Genres des Yegetaux Possiles” (p. 80) — which appeared five years later than 
the “Monographic des Plantes Possiles du Gres Bigarre,” &c., 1817, and in 
which there are good figures of Schizoneura paradoxa — Brongniart makes no 
allusion to any relation of li is genus Zeuyophy Hites to Schizoneura, but 
describes it again as quite a distinct genus, I arrived at the conclusion that
