siidosttirolischen Dolomitstiicke. [S. Tyrol Dolomites, &c.] Sitz, 

 l\ Ak. Wiss. Wien, math.-nat. CI. Abth. 1, Bd. Ixxi. pp. 719-736. 

 Defends Yon Richthofen's view that the Dolomite masses are separate 

 coral-reefs, and not parts of a continuous sheet. Describes their struc- 

 ture, and finds in the conglomeratic portions, and in a peculiar kind 

 of oblique lamination, evidences of the surf on the old reef, while 

 the thin Dolomites at the base of the Eaibl beds would have been 

 formed in the lagoon. E. B. T.

 pp. 100, 101. 



Describes the copper-lodes of St. Augustin in the communes of Cas- 

 tifao and Moltifao on the W. side of the island. The ore is chiefly 

 copper-pyrites ; but there are also some carbonates. The veins run in 

 N. and S. through chloritic schists. An analysis of ore from the Pozzo 

 shaft is given. G. A. L.

The Condroz psammites comprise the beds lying between the Famenne 

 schists below and Dupont's No. I. Division of the Carboniferous Lime- 

 stone. The series is composed of quartzose grits, shales, macigno (argillo- 

 calcareous grit), and anthracite. The fauna consists of 3 Echinoderms, 

 2 Corals, 22 Brachiopods, 17 Lamellibranchs, 8 Gasteropods, 3 Cepha- 

 lopods, and 1 fish. A full list of species is given in a tabulated form 

 (pp. 652-659), and stratigraphical details illustrated by coloured sections 

 are also given. It is on the Ourthe that the series seems to reach its 

 greatest thickness. The following subdivisions are distinguished in as- 

 cending order : — I. Psammites with i\Ji^c^{gauffree) surface of Esneux; 

 II. Nodular Macigno of Souverain-Pre ; III. Paving-stone Psammites 

 of Monfort ; IV. Psammites and Macigno of Evieux. Each of these 

 is further subdivided into Upper, Middle, and Lower. The total thick- 

 ness is about 000 metres. [Reports by Messrs. Dewalque, De Koninck, 

 and Dupont on this communication are to bo found at pp. 469, 476, 

 477 of the same volume.] G. A. L.
