ever, a coherent group of beds, mainly belonging to the upper sub- 
division of the Carboniferous group, thus representing a sea-coast 
facies, nearly equivalent to the dry laud facies of the Upper Carbon- 
iferous sub-division abounding in vegetable remains. 
B. From Borneo. 
The Fusulina-limestones of this island are represented by two 
varieties (probably from different horizons), differing both litlio- 
logically and palmontologically. 
1. The prevalent variety is a somewhat siliceous limestone, un- 
equally speckled with light-yellowish and reddish-grey colours, 
intersected by white and reddish veins and fissures, and abounding 
in large spherical Fusulinee. These occur nearly complete, and some- 
what silicified ; or appear in various sections on the surfaces altered 
by decomposition. The prevalent form, with numerous wliorls of 
the spiral, is essentially different from the form figured by Mr. 
Brady 1 as Fusulina princeps , Ehrenb. sp., showing (like the large 
spherical fornis from Carinthia and Carniola) only six whorls. 
The new species, externally similar to the four-whorled Carinthian 
F. Hoeferi, St., is F. Verbeeki, Geinitz, characterized by the presence 
of from ten to twelve whorls. 
Some sections are referable to Alveolina, or to a genus nearly 
allied ; being types of a new species, Alveolina (?) atavina. 
2. The second variety of Fusulina-rock is a variegated and 
generally fine-grained breccia, including some spherical forrcs, and 
very many sections of more abundant, smaller, cylindrical, thick- 
fusiform or oblong-oval individuais, varying in dimensions. Accord- 
ing to the position of analogous calcareous breccias in the Southern 
Alps, these Bornean breccias may belong to an horizon immediately 
above that of the first variety. 
C. From the Isle of Chios. 
According to Mr. Teller, the Fusulina-limestones here appear so 
widely spread in the form of blocks and smaller fragments, that 
they may be supposed to be a rather important constituent in the 
geological structure of this island. These limestones are grey, and 
include an abundance of broken stenis of Crinoids, togetker with 
rather frequent, large, and elongated Fusulina, standing next to the 
Carinthian F. iSuessi, St., and to the American F. elongata, Shum. 
Certain reddish and yellow portions of the limestone, rather sandy 
and argillaceous, exhibit on their decomposed surfaces several smaller 
forms of Foraminifera.

[Communicated by Count Mahschall, F.C.G.S.] 
A SEAM of earthy brownish coal, with coniferous wood, resting 
on limestone, considered to be Devonian, is worlced at Tchoul- 
kowo, south of Moscow. The coal-seam is overlain by a bed of clay 
with pyritized Cephalopods characteristic of the lowermost Jurassics.
