Description. — Frond tripinnate or possibly further divided. Primary (?) pinnae 

 alternate, linear, touching each other laterally ; secondary pinnae linear, slightly 

 distant or touching each other by their margins, attaining a length of 1'30 cm. with a 

 width of about 4 mm., and bearing from three to six pairs of alternate pinnules accord- 

 ing to position of secondary pinna on the frond. Rachis straight, winged. Pinnules 

 small, 2-3 mm. long and 075 to 1 mm. wide at the base, decurrent, with a dull rough 

 surface. Basal pinnules frequently bear two pairs of lateral sub-opposite lobes 

 without a terminal one or trifid ; middle pinnules usually trifid, or bifid, uppermost 

 ones simple ; lobes or segments of pinnule spreading, blunt. Nervation distinct. A 

 single vein enters the pinnules, which gives off a veinlet to each tooth or segment. 



Remarks. — This species is allied to the Sphenopteris trifida Gopp.,* and to that 

 species I was at first inclined to refer it ; but during a visit from Dr Gothan 1 took 

 the opportunity of showing him the specimens, and his opinion was that the fossil 

 was specifically distinct from that species. Subsequently, through his kind offices, I 

 received from Dr Beyschlag an authentic specimen of Sphenopteris trifida for com-
