more completely preserved remains are submitted. Dalhergia 

 rinkiana, Heer, from the Ataue strata of Greenland, seems to 

 be more nearly related to the species described.

A part-leaflet which betrays especially a similarity with 

 those of the Pterocarjms and Ma cheer iiivi species. The textm-e 

 is rather more firm than that of the species previouslj' de- 

 scribed ; the shape is narrower ; the inequality of the sides is 

 less. The primarj^ nerve is very stout. The seconda,ry nerves, 

 which may only be perceived with difficulty on the charred 

 substance of the fossil, are numerous and close to each other.

C. foliolis coriaceis p)etiolulatis, ohlongis vel ovato-lanceolatis,

Part-leaflets which, according to their shape and nervation, 

 agree perfectly with those of Cassia pseudo-phaseolites, m., of 

 the Tertiary strata of Shag Point, New Zealand, but they are 

 distinguished from these by a firm leathery texture. It is quite 

 possible to assume the connection of this species as regards 

 genus with the Tertiary species named. It is, however, doubt- 

 ful if the Chalk parent species may be enrolled with the same 

 genus as the Tertiary descending species until further actual 

 proofs of tliis are before us. 



I consider Palceocassia angiistifolia, Ett., from the strata 

 of Niederschona, as a vicarious species of the European 

 Chalk flora.
