paper is followed by a more lengthy paper by Engelhardt,*4 who enumerates 
sixty-two species of plants from this region in Bosnia in beds of the Miocene 
age. Two species of Zi/ia from Doboj and Kakanj are described as new. 
The flora shows a considerable mixture of northern and southern forms, and 
includes twenty-six species common to the American Tertiary.—K1rpson* 
has described the Carboniferous plant remains from the border region of 
Canobie and Dumfriesshire, Scotland, and parts of Cumberland and North- 
umberland, England. They include remains from both the lower barren 
measures and from the upper measures, some of the horizons of the latter not 
before known in this region. A new genus, Zsédalia, is proposed for the 
reception of certain fern stems, and a number of new species in other genera 
are described. ARBER and NEWELL” have a paper on homoeomorphy 
among fossil plants illustrating that well-known tendency exhibited in some 
Sroups of unallied forms to show an aggregate of common characters. While 
the term is not exactly synonymous with what has been called convergence, 
it seems to be the same as the term ‘‘homoplasy" as used by the zodlogists 
Lankester and Osborn, or the “‘homomorphy ” of Fiirbringer. POOLE* con- 
tributes a short paper on a remarkably well-preserved section of Stigmaria 
from the coal measures of Stellarton. .The scalariform tissue of the medulla 
8 particularly well shown. There are over thirty vascular bundles, each con- 
taining from five to fifteen radial rows of rectangular cells, with about forty 
cells in each row.—Contributions of minor importance are an anatomical 
paper by Srorrs* on the epidermoidal layer of calamite roots; a paper on 
Xenophyton radiculosum and on a stigmarian rootlet probably related to 
Lepidophloiois JSuliginosus, by WEISS; a paper by KERNER*® describing 
4 new locality for Tertiary plants in Dalmatia; a paper by KipSON™ entitled 
Notes on some Scottish floras of Lower Carboniferousage ; and a paper by 
STERZEL* on the character of the floras of the Carboniferous and Permian 
from the well-known locality of Zwickau in Saxony.— EDWARD W. BERRY.
