they are cones of Fir or of Pine. Pigs. 10, 12 and 13 are acutely pointed acicular leaves, 

 measuring respectively 20 X 2, 30 and 40 X 3 millimetres. The two former especially 

 agree with the leaves of Tsuga, though the appearance of a double mid-rib seems to 

 suggest Sciadopitys. Pig. 11 is a somewhat wider leaf, measuring 25 X 4 millimetres.

Fig. 16 is a small, elongate, narrow seed, with an ample, thinly membranous, pseudo- 

 samaroid wing, twenty-six millimetres long and ten millimetres across at its greatest 

 breadth, belonging apparently to some larger scaled cone than any of those figured. 

 Pigs, 14 and 15 are striated scales with entire margins, twenty-four millimetres in 

 length by twelve in breadth. The seed is apparently of Abies, and the scales may be of 

 the same genus, or possibly of Pinus. 



Several cones, differing equally from each other, and with thin, leathery scales, have 

 been figured by Heer in the " Flora fossilis Arctica," under the name of Pinus {Abies) 

 MacCIurii. The first were described from Banksland in 1868, and are small and 

 cylindrical, with very numerous scales ; the next was a small pointed cone with large scales 

 and seeds from Netlvarsuk, in Greenland, pubUshed in 1874; and the third from Hare 

 Island, identical with our Fig. 2, and pubhshed in 1883. 



I have named my specimens provisionally after the late Professor Heer, with the 

 reservation that, should it subsequently be found possible to define the thin scaled cones
