Seite 6 - ... History of the State of New York " and says: The regents of the University deserve great credit for directing the publication of this catalogue. Nothing is better adapted to secure permanently the interest for public collections and to contribute to their increase than the circulation of such catalogues. We only regret that no more direct reference is made to the individual specimens described and figured in the Natural History of New York. The importance of preserving such records to favor the...
Seite 14 - A specimen subseqnently named by the author after comparison with the type is called a Metatype. ' ' As this is not the meaning given by Thomas, it can not be accepted. The latter* says: The objection to " hypotype" [=metatype] as being too general and covering too many specimens of different origins appiies even more strongly to Lord Walsingham and Mr. Durrani's proposed extension. * * * Many a museum worker, who has to name large series of specimens from all sorts of localities, must constantly...

The chance preservation of some marked features may, indeed, give a hint as to what the whole specimen once was, but too often a suggestion only is thus offered, while the real nature of such types must always remain in doubt. A type in Paleontology should consist of the remains of a single individual, and this should stand as the original representative of the name given. A second specimen, or even more, may be used...
