parallel to the rachis. The result is that the pinna-rachis 

 appears to be accompanied on each side by a nearly straight 

 parallel, longitudinal vein. 



The areas limited by the secondary veins and the mid- 

 ribs are often deeply concave on the impressions of the 

 upper side: this ^ must thus have been bulging out between 

 the veins. Zeiller (1. c; pi. 17, figs. 1 — 5), who has de- 

 scribed, from the Rhaetic of Tonkin, the best specimens 

 known of this species, has been able to state that the fields 

 are filled up by a network of finer veins, which the preser- 

 vation does not permit of being observed in the Swedish 

 specimens. The Swedish fragments appear all to be sterile. 



Woodwardites microlobns is a rather rare species, being 

 known, outside of Scania, only from Franconia, Poland and 

 Tonkin. In Scania it has been found, according to a com- 

 munication by Prof. Nathorst, at Stabbarp. In all these 

 districts the species occurs in Rhaetic beds.

A little fragment, too small for definite identification, 

 may possibly belong to Thaumatopteris Schenki Nath. It 

 consists only of a portion of a pinnule which is somewhat 

 curved, probably accidentally. The specimen is shown in 

 pi. 1, fig. 17. The shape has evidently been linear, and the 

 margin is very slightly incised, with broad, rounded lobes. 

 The venation is indistinct, but appears to resemble that of 

 Thamnatopteris Schenki. 



Thaumatopteris Schenki is known from several localities 

 in the area of the coal-bearing deposits of N.W. Scania, 

 where it characterizes one of the higher horizons of the 

 Rhaetic series. Outside Sweden it has been recorded from 

 Bornholm, Poland and Franconia, occurring in all these dis- 

 tricts in Rhaetic strata.
