96 DR ROBERT KIDSTON ON THE 



a single vein enters, and, dichotomising four or five times in its course, provides from 

 sixteen to over twenty ultimate veinlets, one of which seems to enter each little tooth 

 on the upper margin of the pinnule, but the little teeth are seldom well seen on our 

 specimen, which has suffered somewhat from decay before fossilisation took place. 



ArchsBopteris Reussi is described as bipinnate, but possibly the plant attained a 

 greater size and only fragments of lateral pinnse may be known. I have compared the 

 British example with a small specimen of Archseopteris Reussi from Stradonitz in the 

 British Museum, and find it agrees with it perfectly. 



Hitherto Archseopteris Reussi Ett., sp., appears only to have been found at 

 Stradonitz, Bohemia. 



In the absence of fructification some slight doubt may exist as to whether 

 Archseopteris Reussi should be retained in Archseopteris, though its foliage pinnules 

 agree with that genus in every respect. 



As the only other course would be the creation of a new genus for its reception, and 

 that only distinguished by negative characters, I retain it provisionally in Archseopteris 

 till some knowledge of its fructification is obtained. In any case it is a remarkable 

 circumstance that plants possessing the foliage of the genus Archseopteris, of the 

 Archseopteris hibernica Forbes, sp., type, should disappear from all the intervening 

 rocks that lie between the Upper Old Red Sandstone and the Westphalian Series of the 

 Upper Carboniferous, and should after this great length of time again occur without 

 any apparent generic alteration. 



Archseopteris Reussi seems to have been a smaller species than any of the Upper 

 Old Red Sandstone members of the genus. 



The specimen from Tividale is shown natural size at fig. 7, and some pinnules 

 enlarged 1\ times are given at fig. 7a. 



The fossil is contained in the " Johnson Collection " of the Department of Geology 

 and Palaeontology of the British Museum, No. V., 1366, and my thanks are due to 

 Dr A. Smith Woodward, F.R.S., for kind permission to figure an<7 describe it.
