Two perennial species, one the C. Scouleri of Hooker, named after Dr. Scouler of Glasgow, who accompanied Douglas on his first voyage to the Columbia, and the other the C. monophylla of Nuttall, are confined to the northwest coast. The C. Scouleri is pleatiful at the confluence of the Columbia with the Pacific, and extends in shady woods along the coast. If it be the same as the C. panoia folia of Siberia, why should it not also be found at the Russian settlements towards Sitka? Has the question as to the identity of these two plants been yet determined? The Corydalis macrophylla has been passed over by Douglass as being the same as the C. Scouleri. I know for a certainty he explored repeatedly the Wahlamet woods and prairies, especially about the falls, where the city of Oregon has since been founded, and he must have observed such a plant growing in abundance in that vicinity. If it be specifically different from the C. Scouleri, we are indebted to Mr. Nuttall's discrimination for an addition to the original American stock of this elegant genus.

Lindley in his list gives fifteen genera to the order Fumariaceæ, but only the three that I have gone over belong to North America. The Corydales take a much more extended range than the Dielytræ, and choose also more rocky ground. With them I close my remarks upon the first family or alliance of the large group of albuminose plants,-the RANALES of Lindley, from which he excludes the Sarraceniacere. I believe, however, that whatever relation Sarracenia as a genus may hold to other plants, its position as chosen for it by Torrey, between Nymphæaces and Papaveraceæ, will by most people be considered correct.

ARTICLE V.-Report of the Geological Survey of Canada, 1853 to 1855. (494 pages 8vo., with 4to. Atlas of Maps.

It is some compensation for the absence of regular reports of progress, caused by the occupation of Sir W. E. Logan with the exhibition of Canadian products in Paris, to find the accumulated reports of several years now issued in a respectable volume, with an amount of elaboration and illustration giving them a much more readable and permanent character than that which usually attaches to reports of progress. The present report is in effect a treatise on several important parts of the geology of Canada, illustrated with valuable and accurate maps, and embracing not only the usual accounts of the progress of the survey, but systematic
