genera as Pleurotoma, Fiisus, Buccinum, Bulla, Cerithium, Natica, 

 Venus, etc., during the first decades of the century, are still classified 

 as they then were, in the lists of the fossils from Marseilles before 

 us. The synonyms given are in many instances inaccurate also. It 

 may be said that the second section of the memoir is useful as 

 giving an idea of the richness and general character of the fauna of 

 the Upper Tertiary beds of the localities mentioned, and at any rate 

 it is something to have a complete list of the known species, even 

 although some may be wrongly determined ; but the whole requires 

 very careful revision before it can be of any material value to the 

 systematist. 



The third section gives the distribution in detail of the fossils 

 found, showing their vertical and horizontal ranges, and this is 

 unquestionably the most useful portion of the work. The four 

 plates, which are beautifully executed, re-figure certain characteristic 

 Mollusca and depict five new species which are described in the text.

VI. — Catalogue of Minerals for Sale;. By Geo. L. English 

 AND Co. 8vo. PhiladelphiaandNew York, 1890. Price 25 cents. 



THIS book is no mere dealer's catalogue, but contains a large 

 amount of useful information, concisely arranged for ready 

 reference. A brief resume of the more recently described minerals is 

 given, followed by a classification and list of all known minerals 

 arranged according to their chemical composition. In this list the 

 crystallographic system and the general formulae are mentioned, and 

 the whole is rendered more complete by a good index at the end of 

 the volume. Several figures are given, including eight fine crystals 

 of Beryllonite from Stoneham, Maine.

I.— December 17, 1890.— W. H. Hudleston, Esq., F.E.S., Vice- 

 President, in the Chair. — The following communications were read : 



1. " On Nepheline Eocks in Brazil.— II. The Tingua Mass." By 

 0. A. Derby, Esq., F.G.S. 



In a former paper the general distribution of the nepheline rocks, 

 so far as known, was given with a particular description of a single 

 one, the Serra de Pocos de Caldas. The present paper treats of a 

 second mass, the Serra de Tingua, a high peak of the Serra do Mar, 

 some forty miles from Eio de Janeiro. 



The peak is essentially a mass of foyaite rising to an elevation of 

 1600 metres, on the crest and close to the extremity of a narrow 

 gneiss ridge of a very uniform elevation of about 800 metres. As 

 seen from a distance, the conical outline and a crater-like valley on 

 one side are very suggestive of volcanic topography. In the structure 

 of the mass both massive and fragmental eruptives are found, the 

 former greatly predominating.
