Abstract

Type material for 60 nominal species of
fossil chelicerates are in the Invertebrate
Paleontology Collections of Yale University’s
Peabody Museum of Natural History.
Primary types for 46 nominal species
include 41 holotypes, and 5 syntypes
(representing 3 nominal species). Second-
ary types for 15 nominal species include 31
paratypes. Tertiary types of 19 nominal
species include 35 hypotypes. Most types
are from Mazon Creek (Illinois), Warren
(Pennsylvania), Elmo (Kansas) and Buffalo
(New York) and have been described by
C.E. Beecher, James Hall, E.N. Kjellesvig-
Waering and Alexander Petrunkevitch.

A Type Catalog of Fossil Invertebrates
(Arthropoda: Chelicerata) in the Yale

Peabody Museum

Russell D. White

Introduction

This catalog lists all known fossil chelicerate
types in the Invertebrate Paleontology
Collections housed in Yale University’s
Peabody Museum of Natural History. This
is the third in a series of type catalogs of
fossil invertebrates and is a product of an
ongoing computerization project to improve
the accessibility of the type collections.

During the late 1800s Othniel C. Marsh
acquired many fossils from the area of
Mazon Creek (Grundy County), Illinois for
the Yale Peabody Museum. Several of
these specimens were purchased from S.S.
Strong, a private collector from Morris,
Illinois. Unfortunately, Strong did not
provide specific localities for his collections
and a survey of the O.C. Marsh correspon-
dence in the Yale archives has not pro-
duced a more specific locality than is given
in the text for these specimens.

Organization

Specimens are listed under the originally
described binomen; genera and species
within genera are indexed alphabetically.
Each entry includes the catalog number
used by the Division of Invertebrate
Paleontology prefixed with the abbreviation
YPM and the type status of the original
designation, followed by all known refer-
ences to that name. Any subsequent
designations are listed under the original
designation and are cross-referenced in the
body of the text. Locality descriptions follow

i

Fossil Chelicerata

Postilla 211

i

each entry or set of entries for each
binomen. Errors and inconsistencies are
footnoted at the bottom of each binomen.

The type designations used are holotype
and syntype for name bearers; paratype for
secondary types; hypotype is used for all
tertiary types. Name bearers and second-
ary types are defined as used in the
International Code of Zoological Nomencla-
ture (1985). Tertiary types or hypotypes are
treated here as any described, figured or
measured specimen used in a publication to
augment the knowledge of a previously
defined species, or any referred specimen
that can not be placed unequivocally ina
known species (e.g. Anthracoscorpio (?)
sp.).

Locality descriptions follow each entry or
set of entries with identical locality data.
The locality information includes the
stratigraphy, geography, collector and date.
Stratigraphy has been standardized using
Stratigraphic Nomenclature Databases for
the United States, its Possessions and
Territories (MacLachlan et al., 1992).

two specimens (MCZ 4673 and 4686) described
by Raymond (1944) to be neotypes of this
