Abstract
THE Geological Magazine for December (No. 102) opens with a description by Mr. James Cartro of a new genus and species of fossil Crustacea from the Upper Greensand of Lyme Regis, which the author proposes to name Orithopsis Bonneyi. The fossil which appears to be nearly allied to Necrocarcinus, is figured on a plate accompanying the paper. Mr. C. Lapworth communicates a note on the Graptolitic black shales of the south of Scotland, in which he reiterates his opinion that there si but a single group of these shales, divisible, however, into three divisions—the Lower, Middle, and Upper Moffat shales. The first he regards as of Lower Llaudeilo age, the second as equivalent to the Upper Llaudeilo of Builth, and the third as Caradoc.—From Mr. S. Allport we have a valuable paper on the microscopic structure of the pitchstones and felsites of the island of Arran, in continuation of a former note published in the Geological Magazine. The number also contains a reprint of an interesting paper by Dr. Carpenter on the temperature and other physical conditions of inland seas, in their relation to geological inquiry.—Among the reports, &c., we find Mr. Woodward's sixth report on fossil crustacea, presented to the last meeting of the British Association. This contains a genealogical tree of the Crustacea.
