Abstract 


Type material for 102 nominal species of 
fossil bryozoans is in the Invertebrate 
Paleontology Collections of Yale University’s 
Peabody Museum of Natural History. 
Primary types for 30 nominal species 
include 30 holotypes. Secondary types for 
17 nominal species include 190 paratypes 
(representing 17 nominal species). Tertiary 
types for 82 nominal species include 294 
hypotypes. Most types are from New York 
State, Quebec and Vermont and have been 
described by E.R. Cumings, C.O. Dunbar, 
J.P. Ross and W.H. Twenhofel.

A Type Catalog of 
Fossil Invertebrates (Bryozoa) 
in the Yale Peabody Museum 


Russell D. White and Laura K. Skorina 


Introduction 


This catalog lists all known fossil bryozoan 
types in the Invertebrate Paleontology 
Collections housed in Yale University’s 
Peabody Museum of Natural History. This is 
the thirteenth 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. 

Thirteen type specimens are missing and 
cannot be located. The collections have 
been thoroughly searched by the curatorial 
staff in the 1960s and 1990s and it is 
believed that these specimens are perma- 
nently lost. Missing specimens are indicated 
with a footnote, and any information on their 
whereabouts would be greatly appreciated. 

Sixty specimens, representing five 
nominal species, have been designated by 
Ross (1963a, 1963d, 1963e) syntypes ina 
type series which also includes a holotype 
and paratypes. To eliminate the contradic- 
tion, as the status of these specimens 
remains unclear, they are here referred to 
as “Paratype?” 


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 specimen. Any subsequent

designations are listed under the original 
designation and are cross-referenced in the 
body of the text. Locality descriptions follow 
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, 
for name bearers; paratype for secondary 
types; hypotype is used for all tertiary types. 
Name bearers and secondary types are 
defined as used in the International Code of 
Zoological Nomenclature (ICZN 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, any specimens used in an original 
species description but not explicitly 
designated primary or secondary types, or 
any referenced specimen that cannot be 
placed unequivocally in a known species 
(e.g., Monticulipora sp.). 

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