plementum ad Synopsin Absynthiorum, tentamen de Abrotanis, dissertationem de 
Seriphidiis atque de Dranunculis," designed to convey additional information on 
these subjects, which had previously been treated more at length by the same au- 
thor. 2. Ueber die erste ursache der unebenheit der festen erdoberflaeche 
3. Helices proprie dictae hucusque in limitibus Imperii Russici observatae, a JO- 
ANNE KRYNICKI. This individual appears to have examined the terrestrial mol- 
lusca of Russia with great care, and this communication forms a sequel to others 
already published by him on the same subject. No fewer than forty-one species 
are described in this paper very minutely, with their synonyms given at length, 
and several new species are introduced. In the genus Helicogena (Per.) it is in- 
teresting to remark the occurrence of a species well known in more southern re- 
gions, viz. H. pomatia, which has been found in the wooded and shady districts 
of Volhynia and Poltava, but it must be accounted very rare. Similar observa- 
tions apply to H. nemoralis, which is likewise classed among the rarer kinds. 
.H. hortensis and H. arbustorum, well known species in this country, have spe- 
cial localities assigned to them, a proof that they are by no means generally dis- 
tributed ; the former has been found in Volhynia, the latter in Podolia. 4.

mots sur le Caucase par JEAN KALENICZENKOW. The writer was induced to visit 
the district of the Caucasus by observing that every naturalist who had visited it 
from the time of Pallas, had succeeded in discovering new objects of interest. 
He set out in 1832, and the above paper gives a slight sketch of his proceedings, 
it being his intention to give a more ample account at some future time. He re- 
fers chiefly to the plants observed in his route. In the district of Isioum he de- 
scribes the mountains as calcareous, containing fossil shells and belemnites, and 
they produce many plants entirely foreign to the flora of Kharkov. Beyond 
them appear the plants belonging to the Steppes properly so called, viz. Dic- 
tamnus Fraxinella, Statice Gmelini, Glycyrrhiza ylandulifera (Kit.) Artemisia 
procera, &c. At Moskovskaia, in the government of the Caucasus, he observed 
on the sides of hills inclining to the south, and even on their summits, Xeranthe- 
mum Annettce, Polygala major, Pimpinella Tragium, Rosa pimpinellifolia, Vitis 
vinifera, &c. Near Jessuntouk, the ridges of the limestone mountains are cover- 
ed with Rhus cotinus, Aconitum Anthera, &c. The banks of the impetuous river 
Podkoumok are fringed with Hippothoe rhamnoides, Tamarix gattica and Palisii,
