New Brunswick^ Maine^ and Eastern Canada. 175 



meter at the smaller. It is flattened and imperfectly preserved, 

 but on comparison with my specimens from Gasp^, I cannot 

 observe any specific difference. This species is evidently closely 

 allied to L, nothum, linger, and possibly could perfect specimens 

 of both be obtained, they might prove to be identical. In the 

 mean time ho wever as the scars and leaves of L, nothum are 

 unknown, it is difficult to institute a comparison. 



5. Psilopliyton princeps. — mihi. 



Great numbers of slender bifurcating stems appear on the 

 shales brought from Perry by Mr. Richardson. They are not 

 well preserved ; but it seems scarcely to admit of a doubt that 

 they belong to this species, so characteristic of the Gaspe sand- 

 stones. 



6. Megaphyton ? 



A flattened stem two inches in diameter, irregularly ribbed and 

 striated, appears to show a row of scars on the exposed side, as in 

 the above named genus. The scars are not however well 

 defined. The plant has a slender pyritised axis giving off a 

 few bunches or bundles of vessels to the sides. The structure is 

 ' very imperfect but was possibly scalariform. 



Y. Sternhergia. 



In the collection with which I have been favored by the Natural 

 History Society of Portland, is an impression of a Sternbergia 

 not distinguishable from that of Dad/xcylon Ouangondianumj of 

 St. John, to which species it perhaps belonged. It retains no 

 traces of the wood ; but casts of sternbergia in the same naked 

 condition often occur in the coal measures. 



8. Aporoxyhn, 



Many fragments of carbonised wood showing aporous cells occur 

 in the Perry sandstones : I refer them in the mean time to the 

 above genus of Unger. 



III. Gasp^ Sandstones. 



From these rocks I have but one species to notice at present. 

 It is that referred to in my former paper as probably a Knorria,*
