444 MELVILL : THE PRINCIPLES OF NOMENCLATURE. 
These again are sub-divided into several sections :—(qa) into 
two ; (4) into six; (c) into three. These again are divided 
into many genera: one hundred and ten in all. 
Sir Hans Stoane in his “ History of Jamaica,” 1725, 
alludes to the molluscan productions of that island. He was 
the founder of the British Museum. 
In 1728 J. E. HEBENSTREIT published an ambitious dis- 
sertation on shells, “ De ordinibus conchyliorum methodica 
ratione instituendis,” but it was not so concise or valuable as that 
of Langius, from whom, however, he took many hints, and 
to whose bases of classification he adhered. 
BREYNIUS in 1732 gave to the world “ Dissertatio physica 
de polythalamicis,” an arrangement of shells, recent and fossil. 
He, with Langius and Klein, is considered to be the principal 
pioneer of Linnzeus, Tournefort always excepted. 
Several molluscan writers now came to the fore. Du 
HamMEL and SWAMMERDAM both writing on the Purpura, 
PLANcus, on the minute shells collected in the Adriatic Sea 
near Rimini. 
KUNDMANN a year or two previously, 1728, had published 
“‘Promptuarium rerum naturalium et artificialium.” He followed 
Buonanni exactly in his method of classification. Now comes 
a work much quoted by Linnzeus—D’ARGENVILLE’s “La Con- 
chyliologie,” which went through three editions, and possessed 
a series of plates, with copious figures. 
Almost the first, if not quite the first North American 
publication on the subject was that of BARTRAM, who in 1744, 
issued his “Observations concerning the Salt Water Muscle, 
the Oyster Banks, and the Fresh Water Muscle of Pennsyl- 
vania.” 
JouHNn THEODORE KLEIN published in 1750, at Leyden, 
“‘ Descriptiones tubulorum marinorum,” containing nine plates 
of shells, followed in 1753, by his far-famed “ Tentamen methodi 
J.C., viii., Oct., 1897.
