Remarks. These specimens may be compared with Stachyotaxus sept'entrionalis 
(Agardh), from the Rhsetic of Greenland(l) and Sweden(2). 
Elatocladus conferta appears to be a widely distributed type, occurring in India, 
Australia, New Zealand, and Grahamland. 
Occurrence. Mount Potts, Canterbury (Rhsetic) ; Clent Hills, Canterbury (Rhsetic) ; 
Malvern Hills, Canterbury (? Lower Jurassic); Mokoia, Gore, Southland (Middle Jurassic) ; 
Curio Bay, Waikawa, Southland (Middle Jurassic). 
2. Elatocladus sp. Plate XIII, fig. 9. 
Description oj the Specimen. —The New Zealand Geological Survey collection from 
Waikawa con tarns a single example of a species of Elatocladus with longer leaflets. These 
exceed 1-5 cm. in length, and are uninerved. This specimen is shown enlarged on 
Plate XIII, fig. 9. Unfortunately, it is not only fragmentary but poorly preserved, 
and it appears to be impossible to determine it specifically. 
Remarks. This specimen may, however, be compared with Palissya indica (Old. & 
Morr.)(3), and, so far as I can judge, it is certainly Coniferous, and not a Cyca- 
dophytean frond(4). It also somewhat resembles the Coniferous remains from the 
Rli8etic of Sweden, described by Nathorst as Palceotaxus rediviva Nath.(5). 
Occurrence. —Waikawa, Southland (Middle Jurassic).

Diagnosis. —The following is the diagnosis given by Berry in 1911 : “ Branching leafy 
twigs of large size, stout and thick, apparently branched in approximately one plane. 
Leaves linear-lanceolate, often slightly curved, somewhat equilaterally narrowed into a 
short slightly twisted petiole ; above, gradually narrowed to the acute or subacute tip. 
Length, 8 cm. to 20 cm.; width, 5 mm. to 1-3 cm. The leaves are not crowded, and 
usually appear opposite or subopposite as if inserted on the lateral margins of the stem, 
although at times they seem to be attached to its upper or lower side. As previously 
remarked, none of the material is conclusive in regard to the pfiyllotaxy. Veins 9 to 12 
in number, usually 10, forking only at the base and running parallel until they abut 
against the leaf-margin, about 0-7 mm. apart, somewhat coarser in calibre than in the. 
other members of the genus, distinct on both sides of the lamina, and apparently not 
immersed. Leaf-substance not coriaceous.”
