Observations. One of the leaf-fragments in the present series 
is clearly referable to the above species. It represents about one- 
third of a leaf, together with the jietiole. The venation is 
characteristic in its simple dichotomy, the veins being spaced about 
6 in 4mm. near tlie middle of the leaf. The margin is deejfiy divided. 
The type of leaf is exactly matched by Seward’s figure 9 on pi. IX. 
of his Jurassic Flora, pt. 1. 
Giukgoites digitata is represented in the Ipswich beds (Trias), 
(fiieensland, by a good series, figured by Walkom. 
Distribution. The remains of leaves of the G.digitata type are 
of world-wide distribution, and they range from the Trias to the 
Jurassic. They are more connnonly found in Jurassic strata as 
in the floras of Yorkshire, Franz-Josef Land, Turkestan, India 
Mongolia, Japan, and Victoria (Aust.).
