Abstract
THE Geological Magazine for September (No. 75) opens with an important article by Mr. E. Ray Lankester, describing a new species of Cephalaspis (C. dawsoni) from the Devonian sand-stones of Gaspé, in Canada. This fish is figured, as also a spim, Machairacanthus sulcatus, which was found associated with it. Mr. Lankester also describes the characters of Scaphaspis knerii. —Mr. Davidson continues his descriptions of Italian tertiary Brachiopoda, which he illustrates with two fine plates containing a great number of figures.—Mr. Alfred Marston contributes a paper on the transition beds between the Silurian and Devonian rocks; and Mr. Lankester describes and figures a supposed new species of Terebratula (T. rex), obtained from East Anglian drifts, but probably derived from beds of Portlandian age. The remaining articles in the number are a catalogue of mammalian fossils which have been discovered in Ireland, by Mr. R. H. Scott, and a reply by Archdeacon Pratt to some remarks by M. Delaunay on Mr. Hopkins's method of determining the thickness of the earth's crust.
