THE GEOLOGIST. 



Vienna with a series of fire species of this genus of Spongiaria (Coelo- 

 ptychiwm agaricoides, Goldf., C. deciminum, Boem., C. incisivum, Boem., 

 C. subciferum, Boem., and C. lobaium, Goldf.), all of them beautifully 

 preserved and prepared with uncommon care. These fossils occur near 

 Vordorf, two hours' distance north of Brunswick, in a mass of Upper Cre- 

 taceous Limestone, which at places appears through the uniform diluvial 

 deposits characteristic of the extensive plain of North Germany. Belem- 

 nitella mucronata, D'Orb., B. quadrata, D'Orb., Micraster coranguinum, 

 Lam., and Anancliytes ovata, Lam., are the characteristic organic remains 

 in this limestone. Cceloptychia are not exclusively confined to the upper or 

 Belemnitella-horizons of the Cretaceous deposits. The rarest among them 

 are C. incisum, C. sulciferum, and C. lobatum. 



On the Bayeeuth Sandstones. By Professor Giimbel. — These sand- 

 stones, remarkable for the abundance of fossil vegetable remains preserved 

 in them, are equivalent to the bone-bed strata of Wiirtemberg. They are, 

 iu every locality hitherto known, invariably overlaid by the normal lowest 

 Liassic strata, with Ammonites angulatus, Thalossites, etc. These pas- 

 sage-beds, which are neither decidedly Keuperian, nor properly Liassic, 

 would be best distinguished from both by the special denomination 

 " Ehsetic division." 



On some JNeogene Fossils feom Teansylvania. By Chev. Fr. 

 Bitter von Hauer. — Mr. Bang has presented to the Museum of the Im- 

 perial Geological Institute a series of organic remains from the argillaceous 

 sphserosiderite of Biharcz falva (Transylvania), metamorphized into brown, 

 hydroxide of iron. Among them are many specimens of a Congeria (C. 

 triangularis, Partsch), and a cast of a Paludina (P. Sadleri, Partsch), 

 proving once more the lignitiferous and ferriferous basaltic breccias of 

 Transylvania to be geologically equivalent to the Neogene Cerithian strata.

EEYIEW. 



Popular Geology of Darlington. By R. T. Man son, Vice-President 

 Naturalists' Society. ' DarlingtonTimes ' Office, 1864. 



This little work is in pamphlet form, containing thirty-two pages ; and 

 consists of six articles, originally written for the ' Darlington and Stockton 

 Times,' in 1860, which, having been altered and enlarged, are now re- 

 printed. The first chapter is devoted to the "Buhner stone," in North- 

 gate — a famous granite boulder ; the second, to the quarries near Sheldon 

 station, worked in the " Stinkstein " and Permian beds ; the third, to the 

 coal strata of Thukley and Sheldon ; the fourth, to the great Whin Dyke ; 

 and the fifth, to the Trias of Darlington itself. An appendix, giving the 

 localities for fossils, is added; and acknowledgments to Mr. Howse, of 

 Sunderland, Mr. Janson, of Darlington, Mr. Edward Wood, of Bichmond 

 — the last of whom possesses a most valuable collection of fishes from the 

 locality described — brings this useful, instructive, and popularly written 

 work to a close. Such local books can but induce to spread a taste for re- 

 search and the collecting of fossils. We hope the sale will remunerate the 

 author and publishers.
