Remarks. — For some time I have been under the impression that Schimper has 

 included two distinct types of Calamitic fructification under the name of Calamostachys 

 typica, one a true Calamostachys, the C. Ludwigi, Carr., and the other a Palseostachya. 



A Calamitic cone, agreeing in every respect with those included in the above 

 synonymy, is not uncommon in the Middle and Lower Coal Measures, but none of the 

 figured specimens included above have, as far as I am aware, shown the position of the 

 sporangiophore. A few examples which I have lately examined, especially one from 

 Canon bie,* show that the sporangiophores spring from the axils of the bracts, and that 

 these cones are typical members of the genus Palseostachya. 



For these 1 propose the name of Palseostachya Ettingshauseni, after Dr Constantin 

 von Ettingshausen, by whom this fossil was first figured and described. 



Localities C, D. Very plentiful. 



Paracalamostachys, Weiss. 

 (?) Paracalamostachys Williamsoniana, Weiss. 



1884. Paracalamostachys Williamsonia, Weiss, Sieinkohlen Calamarien, part. ii. p. 193, pi. xxii. fig. 9. 

 1869. Calamodendron commune, (1) Binney, Mem. Lit. and Phil. Soc. Manchester, 3rd ser., vol. iv. p. 

 218, pi. vi. fig. 2. 



Remarks.- — Several small Calamitic cones have been collected, which are most probably 

 referable to this species, but their preservation is too imperfect to admit of a satisfactory 

 determination.
