non-turbinated form ; their living on land or in the water; 
their habits of frequenting the shores or the depths of 
the sea; and even their capability of motion or fixedness,

tica. | 
Pliny, Appian, &c. added nothing, or almost nothing, to 
what Aristotle had done, even in the way of simple facts, 
and most assuredly nothing to their classification. We must 
therefore pass to the writers at the period of the restoration 
of letters. 
The first author who really occupied himself in the distri- 
bution of shells, or in establishing a true conchological sys- 
tem, was, as every one agrees, Daniel Major, in a sort of 
appendix which he placed at the end of a German edition of 
the treatise respecting the Purpura of F. Columna, under the 
title of Ostracologia in ordinem redacta, printed at Kiel, in 
1675. This consists of synoptical tables which conduct to 
genera tolerably natural, but few in number, and established 
only on the species‘observed by Columna. It is to him that 
we are indebted for the division into univalves and multi- 
valves, among which he places the bivalves. 
In 1681, Grew, in his Musewm Regium, or description of 
the collection of the Royal Society, of which he was se- 
cretary, published a systematic and synoptic table of the 
genera of shells, in which he includes all the testa or testa- 
ceous envelopes, and in which, without employing the terms 
at present received, he establishes the division of shells into 
simple, double, and multiple, which corresponds to our uni- 
valves, bivalves, and multivalves. Among the first he sepa- 
rates those which are not voluted from those which are, and 
among the latter those in which the whorls are apparent from 
those in which they are not so, as in the nautili, the cypree. 
Could we have presented this synoptic table it would have — 
been evident that Grew had arrived at the majority of genera
