Chalk of Niederschona ; Q. ellsivorthiana, Lesq., of the North 

 American Chalk formation ; and Q. denticulata, Hear, from the 

 Patoot strata.

A small leathery leaf, which as regards habit reminds me 

 on the one hand of Q. rinkiana, Heer, from the Atane strata, 

 and on the other hand of Q. calliprinos, Webb, of the present 

 time. This fossil was found together with the remains of a 

 leaf of a second species of oak described in the foregoing. The 

 state of preservation leaves much to be desired, and future 

 discoveries must give more exact disclosures as regards its 

 nature. K second fossil leaf, not shown in the illustration, 

 was found at the Grey Eiver. 



Dryophyllum nelsonicum, sp. nov.

Locality : Pakawau, Nelson (Canterbury Museum). 



A fossil leaf which bears the type of Dryophyllum. The 

 texture must be designated as firm and leathery ; the edge is 

 bluntly serrated ; the secondary nerves which feed same are 

 sharply defined and undivided, they are close to each other, 

 little curved, not winding ; the tertiary nerves are pronounced 

 and run almost across (see enlargement, fig. 11a). 



Of the species described already, Dryophyllum holmesii, 

 Lesq., from the flora of the Dakota group, comes nearest to the 

 species above described.
