all belong lo the lanceolatumAype of Lindley & Hutton^ and the 

 sporangium is often found still adhering to the sporophyll. On 

 some of the sporangia the impressions of the spores from the inside 

 can be seen. 



Dr. KiDSTON informs me that he gets similar Lepidophylla both 

 in the lower and upper carboniferous and that they are of no use 

 for zonal purposes. No corresponding form, however, has yet been 

 obtained from Spitsbergen. 



Several of these Lepidophylla show curious markings on their 

 surface (figs. 28, 29, 31), which seem to indicate that there has been 

 some adhering organism when they were floating in the water. 

 The markings are more intricate than the Spirorbis adhering to 

 carboniferous plants. As to the organism to which they are due 

 I have no opinion whatever. 



Whether the two specimens figs. 34 and 35, which are seen 

 in profile and the sporangia of which are relatively great, belong 

 to the same species as the others, is difficult to ascertain ; but I 

 suppose that such may be the case. 



The specimen fig. 37 represents rather a leaf from a branch 

 than a true sporophyll.

Only the small fragment figured represents the Stigmaria in the 

 collection. 



Summary. 



As to the distribution of the différent species within the strata, 

 the material is too poor to allow of any conclusions. The following 

 list, however, gives some information about the localities or strata 

 where the fossils here described have been found. 1 indicates the 

 lowermost stratum (a) of the shale in the section fig. 2, while 3 is 

 one of the intercalating strata of the somewhat coarser shale (b) 

 of the same section. 4—6 are specimens collected about 100 meters 

 eastward from the locality just mentioned: 4 from a loose slab found 

 about 115 meters above sea-level, 5 from the shale in situ 90 meters, 

 and 6 from loose materials 90—115 meters above sea-level. 10 and
