ACKNOWLEDGEMENTS The Chief Scientists, the captains and crews of the ships and especially the Alvin Group and the Remote Vehicle pilots for their invaluable assistance in collecting these specimens. We thank WC-PRURP for its support, Chuck Fisher for donating material to our collections and R. A. Zierenberg and J. McClain for inviting Voight to participate in their cruise. Several individuals, including J. McLean, Los Angeles Co. Museum, S. Hourdez, Station Biologique, Roscoff, France, M. Tsurumi and J. Marcus, University of Victoria, and A. War n, Naturhistoriska Riksmuseet have assisted in specimen identifications. We thank these individuals and the support of the Field Museum Visiting Scholar funds in assisting in the curation of this material.

Please note that this database - like most other such museum systems - is not static. New material is being added, specimens are re-identified by specialists, taxonomic or geographic information is upgraded, material is being used or modified during various research projects (such as histological or molecular preparations). At present, we see a main purpose of this "publication" of the data as a tool to give potential users of our collection advance information about material available by loan or for on-site study.

We claim copyright to our data. The information is available ONLY for not-for-profit scientific use with the stipulation that FMNH be clearly identified as the source of the data. We request copies or reprints of publications that are based on our collections. For commercial requests, questions, comments, and loans, please contact our collection management.

A successful search will display up to 50 records at a time. At the top of each display you will see the record set and the total number of records that matched your search criteria. Data from a record are displayed in the following order:

Catalog Number, Phylum, Class, Family
Identification, Type Status
Ocean, Locality (includes station or dive number, ridge, vent),
Latitude, Longitude
Collector (includes vehicle), Date of Collection
Specimen Count (see below),
Wet (preserved soft parts) or Dry collection,
Preservation Method (see below).

Specimen Count: When the number of individuals in a lot exceeds 25, an 'N' appears in this field. When non-colonial animals have grown together so densely that individual specimens cannot be counted, "Aggregate" appears in this field.

Preservation Method: The symbol '>' indicates the sequence treats with different preservatives. For example, a specimen first fixed in 7-10% buffered seawater formalin and transferred to 70% ethanol appears as 'formalin > 70% EtOH'.
