what wider in its ribs. Being only a part of a single internode, it 

 cannot be certainly determined, though it appears at least to indicate 

 the presence of a species of Galamites in that group. 



13. Calamites canit-^foemis, Brongniart. 



This species, presenting the characters which it exhibits in the 

 Coal-measures, occurs in the ledges west of Carlton, associated with the 

 last species, but in much less abundance. It is a widely distributed 

 species, but has not, I believe, been found previously in rocks older 

 than the Lower Carboniferous, 



14. Calamites ijstoen-atus, sp. nov. PI. XVII. fig. 56. 



Uihs continuous, as in C. Transitionis, hut flat and hroad, the breadth 

 of each being a quarter of an inch in a stem four inches in diameter. 

 Nodes distinct, prominent in the flattened stem, owing to their greater 

 density as compared with the internodes. 



This species is allied to C. Transitionis, but has much wider ribs. 

 It was a woody plant, as, when flattened, a stem four inches in dia- 

 meter affords a film of compact coal about a line in thickness, which is 

 quite as much as a Sigillaria or even a Conifer of the same size would 

 yield under similar circumstances. It much resembles Goeppert's 

 figure of C. variolatus, but wants the stigmata said to be character- 

 istic of that species, — instead of which, it has, in the coaly matter 

 representing the stem, numerous irregularly disposed round spots 

 surrounded by concentric circles ; but these are evidently concre- 

 tionary, and of the same nature with the beautiful concentric con- 

 cretions which appear in some specimens of cherry-coal and of 

 albertite. 



The specimen above described is in Prof. Hall's collection from 

 the Genesee slate, from the shore of Cayuga Lake. A comparison of 

 this specimen with the obscure Calamite-lilie fossils from Kettle Point, 

 Lake Huron, in the collection of the Canadian Survey, referred to in 

 my former paper, satisfies me that they probably belong to the same 

 species. 



{Aster ophyllitecB.) 



15. ASTEEOPHYLLITES ACICULAEIS, Sp. UOV. PI. XIII. fig. I6. 



Btems slender, striated, thickened at the nodes, leafy. Leaves one^ 

 nerved, linear, slightly arcuate, ten to fifteen in a whorl, longer than 

 the internodes. Length of leaves one-half to three-fourths of an inch. 



This plant is abundant in some layers of shale near St. John. It 

 resembles A. foliosa, L. & H., but the leaves are longer, less curved, 

 and more numerous in a whorl. Some of the specimens show that 

 the stem was leafy, as well as the branches ; and I have a specimen, 

 apparently the termination of a main stem, showing the whorls of 

 leaves diminishing in size toward the apex. My specimen of this 

 and the following species of Asterophyllites are from the collections of 

 Messrs. Matthew and Hartt, and were obtained from the ledges and 

 cliffs west of Carlton.
