metre, and preserve the same thickness throughout to their 

 blunted extremities. 



I have not attempted to name this specimen. It may be 

 an Abietites whose minute branches may have lost their 

 leaflets. 



Zeugophyllites elongatus. Morris. 



Stem (?), leaves petiolate, oblong elongate, entire truncate, 

 and slightly thickened at the base ; veins distinct, equal 

 parallel. 



When Morris described the above species from the Jeru- 

 salem Basin he was uncertain as to its affinities, and it is now 

 for many reasons probable that its true alliance is rather 

 with Poa-cordaites among the Goniferce. 



So far as the prevailing Tasmanian forms are concerned 

 the following description of Poa-cordaites would serve equally 

 well with the specific description given by Prof. Morris : — 



Genus Poa-cordaites. Grand 'Eury. 



Leaves, narrow linear, very long, entire slightly attenuated 

 and obtuse at the apex, traversed by almost equal nerves, 

 parallel not dichotomous, connivent at the base, apparently 

 fleshy. 



It is true that M'Coy doubtfully refers the genus to palms, 

 while Tenison- Woods suggests alliance with the cycads near 

 to Podozainites. My own opinion is strongly in favour of a 

 coniferous alliance under Poa-cordaites, because of the inti- 

 mate relation which these linear leaves have with abundant 

 stems and trunks of conifers which, from their beautifully 

 preserved structure, can be referred to the same family 

 Taxineacai (Renault). 



There is the remains of a perfect forest of these coniferous 

 trunks in the Jerusalem Valley in the same formation where 

 these Poa-cordaite-like leaves are so remarkably abundant. 

 Throughout the whole range of the Mesozoic rocks of Tas- 

 mania it is significant that these leaves and coniferous trunks 

 abound. I think, therefore, that the leaves of Zeugophyllites 

 elongatus, Morris, belong to the coniferous trunks with which 

 they are everywhere so intimately associated. ~No other 

 coniferous foliage is found in most places where these trunks 

 are in such profusion. 



Genus, Noeggerathiopsis. 

 Leaves (pinnules or segments ?) wedge-shaped or elongate- 

 spathulate, sub-rhomboid or obovate, margins straight or 

 incurved ; nerves close and numerous, somewhat thick at the 

 base, ancl from thence forking twice or oftener, becoming 

 •slender and diverging.
