Dracnoses OF New TERTIARY Fossils FROM HE SOUTHERN 
Unitep Srares. By W. H. Dall (Proc. U.S. Nat. Mus., X VIII, 
pp. 21-46, 1895). This paper deals mainly with new or misunder- 
stood species of Bulloid Tectibranchs, of Terebra and of Conus. A 
new section of Bullina, Abderospira, is proposed for a new Chipola 
species; and Wakullina is a new subgenus of Cantraine’s genus 
Carolia. A general discussion of the Terebridze of our tertiaries 
precedes the descriptions of new forms. The preliminary remarks 
under Conus have a vastly wider application than to the particular 
genus under discussion, and cut at the root of a false method in 
much paleontologic work of both hemispheres. We refer more 
especially to this paragraph. ‘The italics are our own: “ The gene 
eral rule that local faune are derived from pre-existing faune of the 
same general region is a good guide, and a careful comparison of the 
fossils with the recent types will often assist materially in determin- 
ing the relations of fossil forms. The identifications which travel to 
distant faune for representatives—as, for instance, the Indo-Pacific 
fauna for Haitian fossils—are usually wrong, and all Gabb’s identi- 
fications of this sort will be modified by further and more careful 
study. Analogous characteristics are often purely dynamic in forms of 
different lineage, subjected to similar conditions, in widely separated 
localities. Where modern faune differ in the races of any genus 
which they contain, the antecedent fossils in the same regions are 
not likely to be much more nearly related.” We have, for some 
years, been endeavoring to persuade our German friends of the 
truth of this general doctrine as applied to their tertiary land snails; 
but without much success thus far ; so that it is peculiarly refreshing 
to find an acknowledged master stating the result of his broad experi- 
ence in other groups, in diction so unequivocal as the above extract.
