Description of the Specimens.— The specimen from the Clent Hills, figured on 
1 late I, fig. 7, natural size, is quite the normal type of this species. The pinnules 
have a very broad base, and the nerves arise directly from the rachis. Several other- 
examples occur hi the collection, including forms with very short pinnules only 5 mm. 
long, and others with subcircular leaflets, like those from Owaka Creek shown on 
Plate V, fig. 5. 
Remarks. -This fossil is one of the most characteristic plants of the Triassic rocks of 
the Southern Hemisphere, especially of Australia. It also occurs in South Africa and South 
America, and more rarely in India, in beds of the same age. In Europe and elsewhere 
other species of the same genus are commonly met with in the Rhsetic and Liassic. 
Occurrence. —Clent Hills (Rhaetic) , Owaka Creek, Gatlin’s River (? Rheetic). 
Thinrifeldia sp. Plate II, fig. 11. 
Description of the Specimen .—In Mr. Nmol's collection from Gore a specimen 
occurs of which a drawing is seen on Plate II, fig. 11. Several fragments of pinnae 
are here shown. The left-hand example appears to me to recall Thinnfeldia lancifolia 
(Morris)(1), but most of the others appear to be lobed pinnules, showing various 
degrees of division. Unfortunately, all the leaves are too fragmentary to permit of 
specific determination. 
Occurrence .—Mokoia, Gore (? Lower Jurassic).

Genus CYCADITES Sternberg, 1833.

Cycadites sp. Fig. 10. 
Description of the Specimen. —A small fragment of a frond of Cycadites occurs in 
Professor Marshall’s collection at Dunedin. The leaflets are narrow, and show in 
many cases the paired median nerves. It has not, however, been found possible 
to obtain preparations of the cuticle either in this or other specimens from New 
Zealand, since the preservation is not of the type necessary for this purpose. The 
fragment is too small to permit of specific determination. I refer it to Cycadites 
rather than to Pseudocycas, in accordance with Miss Holden's(2) conclusions on these genera. 
Occurrence. —-Curio Bay, Waikaw’a (Middle Jurassic).
