It represents only a small portion of measures apparently as thick as at Union, seen also in Knoydart Brook and other streams of the vicinity. It is not supposed that either the base or the summit of the series is here given." The above series of strata (exclusive of the "trap") constitute part of the succession to which the term Knoydart formation is applied, in order to separate it from the various members of the Silurian system to the east of and in close relation to the Devonian series. The local divisions of the Silurian fall naturally (and provisionally) into four formations, in descending order as follows :-THE STONEHOUSE FORMATION. THE MOYDART FORMATION. THE ARISAIG FORMATION (LIMITED). For a definition of these formations by the writer, see the January number of the Supplement (No. 1307) to The Scientific American, New York City, p. 20949, in Dr. E. O. Honey's article on the Albany Meeting of the Geological Society of America and the discussion of the papers read. AN HOUR'S BOTANIZING ON THE MOUNTAIN SIDE. By JOHN DEARNESS. On the 8th and 9th November, 1898, the Ontario Entomological Society, at the invitation of the Montreal Branch, held its annual meeting in the Royal city, the date being the twenty-fifth anniversary of the foundation of the Branch just named. On the morning of the 9th, the mountain side afforded an advantageous position to watch the sun rise. The weather was delightful, the air comparatively clear, and not too cool to be pleasant,—a dry, clear, bracing morning. If there were any insects on the wing, they were not conspicuous enough to divert attention from the rich fungal flora in the humid rearward slopes of the wooded terraces. The bareness of the trees and shrubs rendered the cryptogamic forms more noticeable. On the right of the path entering under the inclined railway there were a few dilapidated shrubs, including bladder-nut (Staphylea trifolia). On some of the stems of these shrubs, in a brush heap and on dead erect branches, there was a vigorous growth of three or four species of fungus. One of them is related to the black-knot of the plum (Otthia or Plowrightia morbosa) at least so far as a similar method of fruiting establishes relationship among these forms. Whether the fungus on Staphylea like that on plum has a parasitic stage I cannot say, but in the stage of complete maturity both develop a stromatic layer which becomes thickly covered with fruit-balls, technically called perithecia. Each little shining, papillate globe contains a large number of sacs standing among infertile branches called paraphyses. Each sac or ascus contains eight semi-transparent, centrally constricted spores. The species on Staphylea is illustrated in Plate 41 of Ellis and |
