ver. The coral limestone occupies the same position in Austria 

 and Hungary as it does in Gallicia, and not under the clay, as 

 every one, excepting M. Prevost, thought. New quarries have 

 established this fact in a decisive manner. French geologists had 

 already, through means of the fossils, come to the same conclu- 

 sion, in regard to the coral limestone of Brittany and Manche, 

 which is the calcaire moellon of Marcel de Serres. The under 

 part of the blue clay at Lemberg, in GaUicia, abounds in amber. 

 You already know that the chalk on the Dneister lies upon a 

 reddish sandstone, united by alternations with a limestone con- 

 taining trilobites, orthoceratites, spirifer, productus, bitibulites, 

 or the spines of the Strophomene rugosa. M. Partsch observed 

 in different places of Transylvania the same undermost green- 

 sand formation, with tornatillae, cerithiae, the Gryphaea co- 

 lumba, as in the Alps. The same deposite, with immensely thick 

 beds containing Gryphgea columba, I observed, in company 

 with Kefferstein and Lill, at Orlowa, in the N. W. Carpathian. 

 The same, with beds of nummulite limestone, is met with in 

 Bukowina and at Poyana Starapi.

Begonia diversifolia. 



B. diversifolia ; herbacea, glaberrima ; foliis radicalibus reniformibus late 

 crenatis, caulinis sublobatis inaequaliter argute serratis, superioribus 

 inaequaliter cordatis, inferioribus reniformibus ; floribus axillaribus 

 congestis, pedunculis petiolos sequantibus vel superantibus ramosis ; 

 capsulsE ala maxima acutangula. 

 Desceiptiok — Whole plant smooth and shining. Stem herbaceous, twin- 

 ing, branched, smooth, very obscurely angled, transparent. Stem leaves al- 

 ternate, petioled, half cordate, acuminate, somewhat lobed towards the 

 base, acutely and unequally serrated, smooth, bright green above, paler 

 and somewhat glaucous behind ; nerves branched and prominent behind: 

 petioles shorter than the leaves, spreading, flattened on the upper side. 

 Root-leaves kidney-shaped, nearly equalat the base, broadly crenate, on 

 petioles many times longer than themselves, and which are slightly com. 

 pressed at the sides, and channelled above : a few leaves at the bottom of 

 the stem resemble these, but are on shorter petioles, and have their edges 

 pretty equally lobed, the lobes being unequally and sharply serrated.
