The fossil, fig. 4, represents a. fragment of a fan-palm leaf, 

 which is provided with a long spindle. The specimen reminds 

 one iinmediately of Flabellaria longirhackis, Ung., from the 

 Chalk flora of Muthmannsdorf, in Nether-Austria (see Unger, 

 Icouogr. Plant. Foss., Memoir, bd. iv., p. 19; pi. viii., fig. 1 ; 

 pi. ix., fig. 1), from which it is distinguished by a flatter, 

 more compressed spindle. The pinnate segments are joined 

 to the spindle at an angle of 25°-30°. This circumstance 

 and their less close position to each other correspond 

 exactly to the lowest part of the large fossil leaf described by 

 Unger on pi. viii., the spindle of which, as well as the 

 spindle of our fossil, show's a width of 15mm. 



Besides the fossil depicted, a few shreds of the tips of the 

 pinnffi of this palm-leaf were found in the same locality. 

 These species show distinctly the immense pronounced mid- 

 nerve, and also the fine interstitial nerves which are joined in 

 between the side length-nerves (see the enlargement, fig. 4«).

In the deposit at Grey Eiver were found fragments of 

 small branches, which have knotty joints and rib-like stripes ; 

 their diameter is from 3mm. to 7mm. At Pakawau the 

 twigs found are very thin (see fig. 6), of a diameter of only 

 1mm., in which it VN^as possible to recognise the fine longi- 

 tudinal stripes and the joints ; but in consequence of the 

 defective preservation the sheaths were scarcely perceptible ; 

 however, I was able to discover traces of these only on a
