Linnarsson — On the Eophyton Sandstone. 399 



Eophyton Linnceanum, Torell/ Plate XI. Figs. 3 and 4, and Plate 

 XII. — It is to be hoped that Professor Torell will soon communicate 

 some further observations about this remarkable but as yet not suffi- 

 ciently known species. In the meantime I may venture upon the 

 following remarks. With the materials I have hitherto obtained it 

 is hardly possible to give a full specific description, and I must there- 

 fore confine myself to describing separately some of the specimens 

 collected. In Fig. 3 of Plate XL is shown a piece of sandstone with 

 two specimens lying parallel and close together. The one to the 

 left agrees, as far as I can recollect, with the specimens exhibited by 

 Professor Torell himself, which I had an opportunity of seeing at 

 the last meeting of Scandinavian Naturalists in Christiania. It is a 

 regularly convex fragment of a stem, of equal breadth throughout, 

 and perfectly straight, 170 millimetres long and about 25 millimetres 

 broad, with a height of about six millimetres.' Along its whole 

 length it bears a large number of regular furrows, say 35, the breadth 

 of which is nearly the same as that of the intervening raised ribs. 

 Towards the sides both the furrows and ribs are generally somewhat 

 larger, and especially a few millimetres from the margin one broad 

 and deep furrow is to be seen, besides some ribs raised above the 

 others and at nearly regular distances from one another. These 

 higher ribs are for the most part arranged in pairs and separated by 

 a comparatively broad furrow. Such a pair runs along the middle, 

 and several others are more or less discernable on the right side, 

 this arrangement being less conspiciious on the left side. The 

 smaller ribs and furrows running between the larger are exceedingly 

 fine, and it has not therefore been possible to represent them all 

 distinctly enough in the figure, since even in the original they are 

 to be distinguished only with difficulty. All the ribs and furrows 

 are straight except in the uppermost part (a), where those in the 

 middle are gently bent asunder, as though nearly the origin of a 

 branch. On the sides of the stem (h and c) are to be seen awl-like 

 appendages, the organic connexion of which with the stem is some- 

 what uncertain. 



The specimen on the right hand is depressed and mutilated and 

 not visible throughout its whole breadth, which must have been 

 considerable, the preserved portion being more than 25 millimetres 

 broad. The ribs and furrows are much coarser and much less re- 

 gularly arranged. On the left side they are comparatively equal 

 and small in size, though coarser than in the former specimen. 

 Further to the right hand the breadth of the furrows is much larger, 

 sometimes amounting even to three millimetres. The ribs are several 

 times narrower than the furrows, the coarser among them being 

 often divided. Even in this specimen they are for the most part 

 straight, but near the left margin the outer ones (d) bend outwards, 

 probably where a branch has been given off. Close above this 

 flexion the sculpture is effaced ; when the furrows in the upper part 

 again appear, they run quite straight.

 ^ In the figure the inner part of the right side appears more depressed than in the 

 original.
