mentioned it, is no doubt Cretaceous. However, I myself found it 

 only at Cape de la Jonquière, a little below its Inoceramus horizon. 

 The basal nerves, which count five or more, run radially upwards 

 altogether from the same point at the top of the petiole. The 

 midrib does not differ essentially from the laterals, and forks 

 sometimes soon after the origin. The Cretaceous Hechra cuneata 

 He.^^ and H. primordialis Sap.*^ is also not far distant from our 

 species. H. McCluril Hk. has until now only been found in 

 Greenland, Spitzbergen, and on the McKenzie river in Canada.

Impressions, very similar to those described by Heer from 

 Mgach and Dui, have now been found in several places. Having 

 not now at my disposal all I collected, I simply follow the nomen- 

 clature of Heer. His specimen from Mgach is doubtless Cretaceous ; 

 but the locality at Dui is very difficult to identify owing to the 

 indefinite use of this place name. Heer has determined the geo- 

 logical position as the lowermost Tertiary. Perhaps his locahty 

 " Dui " (only in this case ; because in other cases he called by 

 this name a locality near Cape Khoinju) here corresponds to the 

 modern " Cape de la Jonquière," that is the place of the " inverted 

 series " of Schmidt. 



Heer himself compares the present species with V. Whimperp
