1. — A Review of the Flora of the Little River Group. By 

 G. F. Matthew, D.Sc, etc. Trans. Roy. Soc. Can., Second Series, 

 1906, vol. xii, sec. iv, p. 99. 

 rpHIS is the first of a series of articles by Dr. Matthew on the ancient 

 J_ fl-ora, the species of which were described by Sir W. J. Dawson 

 many years ago. The present paper is devoted to the Equisetales, and 

 a number of new forms are described in it. Two new genera are 

 described, found in the lowermost group of plant beds — Ramicalamiis 

 and Lepidocalamus. Dr. Matthew finds Calamites Suckovii common, 

 a species which is found in the uppermost beds of the Carboniferous, 

 and therefore must have had a great vertical range. The genua 

 Asterocalamites {Calamites transitionis of Dawson) is found to be 

 common. 



Asterophyllites and Annularia are represented in a number of 

 species, including some in which the leaves are clustered in whorls, 

 and so not evenly distributed. The early development of the 

 Equisetales, as shown by this flora, is commented on in the closing 

 paragraphs of this article, 



2. — A New Species and a New Genus of Devonian Plants. By 

 G. F. Matthew, F.R.S.C. Bull. Nat. Hist. Soc. of New Brunswick, 

 1906, vol. V, pt. iv, p. 393. 



THE plant here described is referred to the Ferns, and thought to 

 be related to Eremopteris and Triphyllopteris. The leaves of the 

 barren frond were narrowly wedge-shaped, and there was a fertile 

 pinnule with pod-like receptacles. The name adopted for this plant 

 is Pseudohaiera Mclntoshi. With this occurs a vigorous-growing 

 mutation of Annularia longifolia, Brong., and other species of plants. 

 The locality is near St. John, N.B., Canada. 



3. — On some Species of Silurian and Devonian Plants. By G. F. 

 Matthew, LL.D., etc. Trans. Roy. Soc. Can., Third Series, 

 vol. i, sec. iv, p. 185. 



A FEW Acrogens from vai'ious localities in the provinces of New 

 Brunswick and Nova Scotia in Canada are described in this 

 paper. A cone of Lepidodendron of Eo-Devonian ; a supposed lichen 

 of the same age or older, and plants from the Upper Devonian of 

 Nova Scotia and N.B. Two interesting fungi which grew between 

 the wood and epidermis of certain large ferns are described, and also 

 a new species of Psilophyton which may have been of greater 

 antiquit)-. Lepidodendron corrugatum and Aneimites Acadica are 

 common forms of the Upper Devonian flora.

ALOW tj'pe of calcareous organism found in the pre-Cambrian 

 rocks of St. John, N.B,, Canada, and thought to be related to 

 the Cryptozoon found in the pre-Cambrian deposits of the Rocky
