aider that these overlying sandstones are of Upper Triassic age." But 

 Professor Judd in his admirable researches on the Secondary Eocks of 

 Scotland, |(Quarterly Journal of the Geological Society, Vol. XXIX., p. 97,) 

 has been able to show that the evidence derived from the examination 

 of these rocks in the field is also conclusive as to their really being of 

 Keuper age. The district round Elgin is tremendously faulted, and the 

 rocks are so overlaid by drift that no clear sections are there obtainable ; 

 but when we cross to Dunrobin, on the north side of the Moray Firth, we 

 find the same yellow sandstones conformably overlaid by the Lias, and 

 resting quite unconformably on the Old Red Sandstone. In the memoir, 

 Professor Huxley describes, in his usually masterly manner, the scutes, 

 vertebrae, teeth, and bones of Stagonolepis Robertsoni. It must have been 

 a reptile twelve or fourteen feet long, resembling the existing Nils 

 crocodile, or the caimans or jacares of tropical rivers. The footprints 

 from the Cummiagstone quarry near Elgin are not associated with any 

 fossil remains, and the author is not able to refer them certainly 

 to any known form. There can be no doubt but that the Trias is worthy 

 of a far more minut9 study than it has hitherto received at the hands of 

 Midland geologists ; the sandstones both of Lower and Upper Keuper 

 age, such a3 occur at Inkberrow in Worcestershire, for example, are often 

 covered with markings of most varied forms, and invariably yield 

 evidences of life when carefully examined. This able work of Professor 

 Huxley's should be a help to all workers in such strata ; the admirable 

 plates especially will give them a good idea of "what to look for."

The London Catalogue of British Mosses and Hepaticce. Second Edition. 

 London : David Bogue. 30 pp. Price 6d. 



This is a great improvement on the former edition, the addition of a full 

 list of the British Hepaticse will be a great boon to all collectors of these 

 plants. As it is printed in single columns to a page it will be very con- 

 venient for interleaving and will be useful not only as a check list, but 

 also as a note book for the working Botanist.

A Review of the British Characece. By Henry and James Groves 

 London : West, Newman and Co. Price 2s. 



This valuable addition to our cryptogamic literature is reprinted 

 from the " Journal of Botany" for 1880, and offers to British botanists 

 a reliable and useful aid to the study of this much-neglected class of 

 plants. A full account is given of the various British botanists who 

 have published their remarks on the genu3, from Gerarde down to the 

 latest papers that have appeared in the " Journal of Botany." The 

 synonyms of each species from both British and foreign authors is also 

 given ; the value of these will be felt by every student of botany. The
