" Teschenite " by Hoiienegger, that range in a narrrow band along 

 the northern edge of the Carpathians ; and assigns to them an Upper 

 Eocene age Franz Posepny gives a short note on the occurrence 

 of some Jurassic rocks in Eastern Gralicia. Ferdinand Ambroz 

 communicates some observations on the rocks and minerals of the 

 neighbourhood of Padert. The Barometrical Heights observed in 

 Bohemia by the Greological Surveyors during 1861 and 1862, are 

 recorded by H. Wolf. The rocks and minerals of the Stiibing- 

 graben, to the north of G-ratz, in Steyermark, are noticed by Michael 

 Simettinger. The periodical account of analyses made in the 

 chemical laboratory of the Institute next follows — lignites, coals, 

 limestones, and mineral waters, sent for examination, are reported 

 on by Karl Eitter von Hemer. Lists of presents to the Insti- 

 tute, and reports of the proceedings of its meetings, complete this 

 Part of the Jahrbuch. T. E. J.

Geological Society op London. — I. May 23, 1866. — Professor 

 A. C. Eamsay, F.E.S., Vice-president, in the chair. The following 

 communications were read : — 1. " Notes on the Geology of Mount 

 Sinai." By the Eev. F. W. Holland, Communicated by Sir E. 

 I. Murchison, Bart., K.C.B., F.E.S., F.G.S. 



The physical features of the peninsula were described as exhibit- 

 ing in the north an extensive table-land of limestone of Cretaceous 

 age, supported and enclosed on the south by a long range of moun- 

 tains composed of syenite, porphyries, and schistose rocks. Near 

 Jebal Serbal is a mountain of Nummulitic limestone ; and a limestone, 

 apparently of more recent date, occurs near Tor and Eas Mohammed. 

 The author further stated that in some parts of the peninsula the 

 syenite mountains are capped by a considerable thickness of hori- 

 zontal beds of sandstone, which are unaltered at their contact with 

 the syenite. This sandstone formed the gTeat mining district of the 

 Egyptians in Sinai, and is now worked for turquoises, which appear 

 to occur more or less in veins. Eaised beaches were discovered by 

 the author on the western side of the peninsula, at elevations of 

 from 20 to 30 feet. 



2. "■ On a new genus of Phyllopodous Crustacea from the Moffat 

 Shales (Lower Silurian), Dumfriesshire." By Henry Woodward, 

 Esq., F.G.S., F.Z.S. 



The fossil described consisted of the disk-shaped shield, or cara- 

 pace, of an Apus-like Crustacean, the nearest known form to it 

 being Peltocaris ajptychoides, Salter, from which, however, it is at 

 once distinguished by the absence of a dorsal furrow. 



A line of suture divides the wedge-shaped rostral portion of the 

 shield from the rest of the carapace, the two parts being seldom 

 found together. From their strong resemblance to Discina, the 

 author proposed for them the generic name Dlscinocaris, and named
