Genus Nilssonia, Brongniart, 
Nilssonia sp. 
Fig. 41. 
An imperfect fragment of a frond, (161, allotment 53a, Jumbunna), 4cm. 
in length, the rachis being represented by a broad groove from which are given 
off truncate segments preserved in such a manner as to show no trace of veins. 
The form of the frond is similar to that of Nilssonia compta, Phill., an inferior 
oolite species, and of N. Schaumburgensis , Dunk., of wealden age. Some 
fragments figured by Shirley as Pterophyllum Yerongense* * * § from Yeronge may 
possibly be identical with the form represented in Fig. 41, but the material is 
too scanty to admit of a definite expression of opinion. 
Among' Indian species, a specimen figured by Feistmantel as Anomo- 
zamites Lindleyanus f agrees most closely with the fragment shown in Fig. 41. 
The material is too meagre to enable one to decide between Anomozamites 
and Nilssonia as the more suitable designation. 
CLASS CONIFERALES. 
Family Araucariejs. 
GENUS ARAUCARITES, PRESL. 
Araucarites sp. A. 
Fig 42. 
Fig. 42 (77, allotment 62, Jumbunna).—The single scale, P8cm. in length, 
represented in the figure is probably that of an Araucarian cone, there is a 
central depressed area, which no doubt marks the position of the single seed, 
with a slightly projecting ridge on each side. This form of scale may be 
compared with that of Araucarites Phillipsi, Carr.,i and with Feistmantel’s 
A. Cutchensis .§ The narrower end is that by which the scale was attached 
to the cone ; close to the broader distal margin there is a slightly projecting 
point, shown as a darker dot in the drawing, which may represent the so-called 
ligule of certain types of recent Araucarice, but the preservation is not suffi¬ 
ciently clear to admit of a more complete description. On the whole the scale 
suggests a comparison with those of the female cones of such species of 
Araucaria as A. Cookii, A. Rulei, &c., which belong to the section Eutacta. 
Araucarites, sp. B. 
Fig. 43. 
Fig. 43 (146, allotment 50, Jumbunna East).—This smaller and broader 
scale shows very clearly the impression of a single central seed, and exhibits 
still closer agreement with the Eutacta type of cone-scale among recent 
Araucarise.
