THE GEOLOGIST. 
Vienna with a series of five species of this jg^enus of Spongiaria (Ccelo- 
ptychium agaricoides, Goldf., C. deciminum, Eoem., C. incidvum, Koem,, 
C. siihciferum, Koem., and C. lohatum, 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 Ananchytes ovata, Lam., are the characteristic organic remains 
in this limestone. Coeloptychia are not exclusively'' confined to the upper or 
Belemnitella-horizons of the Cretaceous deposits. The rarest among them 
are C. incisum, C. stdc/ferum, and C. lohatum. 
On the Baykeuth 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 Wilrtemberg. They are, 
in 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 
" Ehietic division." 
On some Neogene Fossils from Transylvania. By Chev. Fr. 
Ritter von Hauer. — Mr. Bang has presented to the Museum of the Im- 
perial Geological Institute a series of organic remains from the argillaceous 
sphaerosiderite 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 theNeogene Cerithian strata.

EEVIEW. 
Popular Geology of Darlington. By H. T. Man son, Vice-President 
Naturalists' Society. ' DarlingtonTimes ' Office, 1864. 
This little work is in pamphlet form, containing thirty-tw^o 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 "Bulmer 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 Darhngton, Mr. Edward Wood, of Richmond 
— 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 wdll remunerate the 
author and publishers.
