UCLA Malacology Collection 1919-1973

Section Responsible for Processing (Top)


Significance (Top)

Ulysses. S. Grant IV established the University of California, Los Angeles (UCLA) recent mollusk collection in the 1920s. It was used as a research and comparison resource in their Geology Department (now the Earth & Space Science Department). Dr. Willis P. Popenoe and LouElla R. Saul maintained the collection until it was transferred to NHMLAC in 1985. Its addition to the Museum strengthens our representation of the entire Molluska phylum and greatly expands our distribution records of dozens of species.

Background (Top)

UCLA researchers frequently used their recent mollusk collection to compare fossil mollusks to living cognate species.
Principal investigators who used and added to this collection include E. Jestes, E.H. Quayle, G. Willett, and J. Zetek. Donors who provided significant additions to the collection include J. and R. Burch, A.G. Fischer, J. Golisch, H.N. Lowe, T. and I. Oldroyd, and A.M. Strong. K. Hatai, a professor at the University College Achimoto in Japan, strengthened UCLA's Asia-Pacific respresentation through a specimen exchange program.

Integrating the UCLA holdings into our own has revealed new species, and description papers are in progress.

Collection Location and Dates (Top)

Specimens were collected from over 50 countries representing much of coastal Earth, including North, Central, and South America, the Pacific Rim and Austral-Asia, India and Pakistan, the Mediterranean and the Middle East, coastal Europe, and sections of Africa as well as many islands throughout the South Pacific. Collection dates range from 1919 to 1973.

Taxonomic Contents (Top)

Primarily a general collection, the UCLA holdings thoroughly represent shelled gastropods, bivalves, and chitons. Cephalopods and scaphopods are also partially represented. The holdings are particularly rich in Alaskan mollusks collected by George Willett in the 1930s and 1940s.

Documentation (Top)

A collection inventory is contained in several ledger books and in a single 10 drawer file cabinet with taxa noted on 3" x 5" index cards. As the ledger books also include specimen lots of fossils, they are housed in the Invertebrate Paleontology section at the South Grand Warehouse. The card file is in the offices of the Malacology section of NHMLAC.

Description of Collection (Top)

A survey of Mugu Lagoon was conducted as a UCLA graduate student project (John Warme, PI) at Mugu Lagoon, and is wet-preserved in 20 1-gallon jars. The rest of the collection is almost entirely dry-preserved. These holdings come to us systematically arranged into gastropods, bivalves, chitons, cephalopods, and scaphopods. They are divided into two collections:
1) a world-wide research collection fully curated by former UCLA and NHMLAC staff member LouElla Saul
2) a predominantly non-curated world-wide collection.

In 1985, the year the collection was donated, we moved it to the East Lake Warehouse, a multi-use LA county facility. We moved it again in 1988 to the North Grand Warehouse. Between November 18 amd 21, 2002, the curated part of the collection was packed and moved to NHM's 3rd floor East wing hallway. As lots are processed they are integrated into the cabinets of the Molluska collection on the 3rd floor.

Part 2 of the collection is still stored in the southwest corner of the North Grand Warehouse in poor conditions: there are no environmental controls and inadequate lighting at a facility that is prone to leaks.

Collection Inventory (Top)

The curated collection is contained in 28 metal "UCLA-type" cabinets with 12 drawers each [1 metal "UCLA-type" cabinet approximately equals 2 Lane cases]. If each metal cabinet contains at least 2 trays per drawer with roughly 30 lots per tray,

30 lots/tray x 2 trays/drawer x 12 drawers/cabinet x 28 cabinets =
approximately 20,160 lots.

The non-curated collection is in 15 upright wood "UCLA-type" cabinets that contain 57 drawers each. The number of trays in each cabinet varies, but with an estimated 40 trays/cabinet x 15 cabinets = 600 trays each with approximately 20 lots/tray = 12,000 lots. Thus the total estimated number of lots within this collection is 32,160.

Much of the collection was curated to museum standards at UCLA. Former Malacology collection manager Cliff Coney curated the UCLA freshwater bivalves into the NHMLAC collection in the early 1990s, but the rest is not curated to museum standards, if at all. [NOTE: During the UCLA collection move from the East Lake Warehouse to the North Grand Warehouse in 1988, a wooden case was toppled and its contents may be a total loss].

Collection Assets (Top)

No collection assets available.

Specimen Condition (Top)

Date 4: New alcohol needed immediately (specimens will otherwise be irreparably damaged) 3: Containers need to be 'topped off' 2: New alcohol needed within next 6-12 months 1: No curation needed at present
01/05/2005 0% 0% 0% 100%
08/29/2001 100% 0% 0% 0%
Most of collection is dry. Wet preserved specimens need new alcohol. These percentages refer to the well curated part of the UCLA collection that is housed at the NHMLAC.

Container Condition (Top)

Date 4: Immediate short-term (less than 5 years) storage container replacement needed. Present containers are inadequate. Curate in the short-term with plastic buckets, whirltop bags, or similar. 3: Specimens contained in museum-grade long-term (greater than 5 years) storage containers. Jars need new closures (e.g. replace Bakelite and metal lids). 2: Transfer to museum-grade long-term storage containers. Replace or transfer to new jars and glass vials, replace cotton and closures. 1: Containers are museum-grade and meet highest curation standards.

Specimens that can not be accomodated into the collection are being stored in UCLA cabinets in third floor hallway.
08/29/2001 0% 100% 0% 0%
This collection is curated to museum standards but is in need of rehousing in standard NHMLAC Malacology vials and trays.

Label Condition (Top)

Date 4: New labels needed immediately (original labels in poor condition, paper torn/worn, legibility poor). 3: New labels needed within next 1-2 years (original labels beginning to wear, pencil writing fading, low quality paper was used). 2: New labels needed are as a result of curation and accretion of collection. 1: No new labels needed at present.
01/05/2005 0% 0% 0% 100%

04/26/2004 0% 0% 50% 50%
08/29/2001 0% 0% 100% 0%
Most lots are labeled, but collection needs standard NHMLAC Malacology labels.

Label Content (Top)

Date 2: New label or additional label needed because original label data is incomplete and supporting documentation provides additional collection data which greately enhances significance and value of each lot. 1: Label content complete. All collection data are contained on label.
01/05/2005 0% 100%
08/29/2001 0% 100%
Label data is mostly complete, but collection needs standard NHMLAC Malacology labels.

Level of Taxonomic Identification (Top)

Date 7: Not identified 6: Phylum 5: Class 4: Order 3: Family 2: Genus 1: Species
01/15/2005 0% 0% 0% 0% 0% 1% 99%

08/29/2001 5% 0% 0% 0% 0% 5% 90%
These percentages refer to the well curated part of the UCLA collection noted above. The poorly curated and non-curated portion of the collection is approximately 85% not identified and 15% identified to species-level.
