446 MELVILL: THE PRINCIPLES OF NOMENCLATURE. 
Between 1750 and 1760 flourished CoHanskEn, of Frankfort, 
the author of ‘‘ Conspectus sciographius Testaceorum ;” NICOLAS 
GEORGE GEVE, of Hamburg, editor of an illustrated periodical 
devoted to sea productions, and GUETTARD, 1756, who pub- 
lished in the Memoirs of the French Academy some new 
genera of shells, several of which are still recognized, having 
been adopted by subsequent binomial authors. His principal 
work was styled ‘‘Sur la rapport qu’ll ya entre les coraux et les 
tuyaux marins.” 
Our countryman, Dr. PaTRICK BROWNE, in 1756, published 
“A Civil and Natural History of Jamaica.” Some of his genera 
are still adhered to. 
The immediate predecessor of Linnzeus in mollusca was 
the famous MicHAEL ADANSON, whose chief work ‘ T/histoire 
naturelle du Senegal,” was published in 1757. He was born 
in Provence in 1727. The above work contained an enu- 
meration ot Mollusca, both generic and specific, many of the 
names preterred being not classical, e.g., Mesal, Nifat, Mutel, 
Tafon, Sigaret, etc. He was just one year behind the date 
of the tenth edition of the “Systema Nature,” which certainly 
interfered with the permanence of his work. His memory has, 
however, always been highly honoured, especially by the 
naturalists of Europe. Linnzeus named in his honour the most 
famous perhaps of all trees, the Baobab Tree of Africa (Adan- 
sonia digitata), and MM. Crosse and Fischer have also described 
the superb Pleurotomaria from Guadaloupe, a specimen of 
which adorns our National Museum at South Kensington, as 
P. Adansoniana. 
CaRL VON LINNE, commonly known as Linnus, was born 
May 13th (old style), 1707, at Rashault, province of Swaland, 
Sweden. Putting aside his labours and fame as a Botanist and 
Zoologist in other branches than the mollusca, we find that in 
1746 he gives an account of many species of shells in the 
‘Fauna Suecica.” This was followed in 1747 by the results of 
J.C., viii., Oct., 1897.
