previously doscribcd si)ocies, altlioiij^li in one or two eases there are 

 certain j^eneral resemblances which may prove to have greater signili- 

 cance when more complete material is secured. It Avill, therefore, be 

 sufficient to place their descriptions on record. 



No. 1^4: is a tVaj^iuent of a small, branching i)lant of very imperfect 

 preservation and obscure characters. 



No. 45 is a frauinent of some large plant, which shows a nund)er of 

 coarse, parallel stri;e, the fragment being too small to exhibit their 

 terminations. 1 should be inclined to refer this to Calamitcs transi- 

 tionis Giipp. or to some closely allied species.* C()mi)arison should be 

 made with (hdamitcs ramosus Artis., and C. jjuchydcnua J>rongn.;t 

 also with Bornia radiata Brong.f and B. scrobieiilata Sterub.§ 



Nos. (» and 7 are probably structures of the same nature. They rep- 

 resent aggregations of similar, simple, straight lilanients about 1.5 to 

 2mm ju diameter, disposed in a parallel manner. They Avere originally 

 structures of considerable volunu^, as their transverse section is nearly 

 round. It is not unlikely that they represent roots, but it is impossi- 

 ble to assign them to any particular plant. 



Nos. 27 and 37 are fragments of similar linear, branching stems, 11 

 and 12^'" h)ng by 3 and 5""" wide. They sho^v uo structure whatever 

 and can not at ])resent be referred to any species. 



No. 38 is a fragment of a stem without branches, S'^'" long and 1.5<^'" 

 wide. It shows uo structure beyond four longitudinal and parallel 

 ridges or nerves, which are about equidistant. It is probable that 

 this nuiy be a fragment of the same species as No. 25. 



No. 41 is a narrow stem 12*"'" long and 3""" wide, showing no lateral 

 nuMubers for a distance of 7^'"' beyond which there appear, on op])osite 

 sides, what are either the stumps of branches, or more probably, per- 

 haps, the basal portions of leaves. They are distant 3*^'". The speci- 

 men bears a slight resemblance to Parla (1eci2>iinfi, but the relation 

 can not be satisfactorily established. 



Nos. 23 and 40 are of the same nature. Each is a small fragment of 

 a stem showing near one end a pair of branches or leaves, of which only 

 the basal portions remain. The stem is 4""" wide. The specimens are 

 altogether too fragmentary to admit of their reference to any species, 

 but in this connection referenc*' should be made to Calamitcs radiatusW 

 Brongn. (Archwocalamitcs, Stcrub.), as it is quite possible these frag- 

 ments may be parts of this plant.
