Allan Hancock Foundation / Sponge and Misc. Invertebrate Collections

Section Responsible for Processing (Top)

MBC

Significance (Top)

In March 2003 these Allan Hancock Foundation Collections were physically moved to the NHMLAC. These collections represent the AHF Porifera Collection (both type and non-type material) and also include a large number of other invertebrates.

Background (Top)

These collections are the result of decades of collecting by Allan Hancock staff, curators, students, and R/V Velero III and IV Expeditions.
See Dickinson, M. G. 1945. Sponges of the Gulf of California. Allan Hancock Pacific Expeditions 11: 1-252.

Collection Location and Dates (Top)

MBPC staff moved these collections from the Allan Hancock Building on the University of Southern California, Los Angeles campus to the NHMLAC. As plastic and wooden crates and pallets are unpacked and specimens processed, the collection is being moved from the ground floor corridors to the MBPC storage spaces. Wet-preserved materials are being maintained on-site in the NHMLAC main facility on MBPC compactors. Dry material is stored at the North Grand Warehouse.

Taxonomic Contents (Top)

The collection contains both wet preserved and dry specimens. The majority of the specimens are wet preserved. Taxa in this collection include: Porifera, Cnidaria, Ctenophora, Plathyhelminthes, Nemertea, Nematoda, Nematomorpha, Acanthocephala, Sipuncula, Echiura, Annelida, Ectoprocta, Brachiopoda, Chaetognatha, Hemichoradata, Urochordata, Echinodermata, Mollusca, and Crustacea.

The collection can be roughly broken into: (1) identified wet preserved and dry general Porifera, (2) Porifera type specimens, (3) identified and unidentified Porifera "voucher" collections, and (4) identified and unidentified other wet preserved and dry invertebrates.

Documentation (Top)

A card cabinet containing Dr. Bakus' "Porifera cards" is located in the Polychaete Storage Room. The cabinet contains Porifera classification cards (3 drawers) and catalog cards (1 drawer). The Porifera classification cards are ordered alphabetically by genus. They include classificatory information as well as genus and species authors, synonomies, etc. The catalog cards, referring to Hydrozoa, contain unordered Velero Station numbers, collection date, location, and depth. Often remarks on by-catch and habitat are included. It is unclear if the Hydrozoa referred to here are actually contained (mixed in with the sponge collection housed at the NHMLAC) or are dispersed elsewhere (and not part of the NHMLAC collections at all).

Description of Collection (Top)

The portion of the collection labelled "voucher" collection occupies four shelves. Porifera are arranged taxonomically. Crustaceans, molluscs, echinoderms, and polychaetes are being moved to the appropriate sections. The remaining taxa are being incorporated into the NHMLAC general invertebrate collection located in the MBPC portion of the Polychaete Collection Room. Wet preserved specimens are preserved in 70% ethanol. Some or all specimens may have previously been exposed to formalin.

Collection Inventory (Top)

The collection is approximately 42 buckets, 21 metal drawers, 40 plastic storage boxes and 7 pallets. Two of these pallets are reprints. The remaining five pallets contain roughly 25 wooden crates each. Each crate on average holds 25 specimen jars.
As of April 2004, this collection has been curated and is being stored inthe Polychaete Collection Range on 20 banks of shelving. The following description is of the wet preserved lots.
The identified Porifera specimens (~500 lots) are arranged taxonomically. The unidentified Porifera (~2,000 lots) occupy 8 banks of shelving. Dr. Bakus' voucher collection (~200 lots) occupies four shelves. There are possibly ~230 type specimens (mostly mixed in with the general collection, as these are not clearly designated and labeled as such). Another ~1000 lots are mixed invertebrate phyla that still require sorting. The identified "other" taxa (~1700 lots) include: crustaceans, echinoderms, polychaetes, mollusks, urochordates, cnidarians, platyhelminthes, nematodes, ascidians, and fish.

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

12/24/2003 0% 12% 28% 60%
Approximately 65% of the wet preserved portion of the collection is stored in bailtop jars and jars with metal or Bakelite lids and has been moved to proper collection facilities. The remaining 35% is temporarily being stored on pallets in corridors on the ground floor. Category 3 are lots on pallets, presently drying out; category 2 are lots on pallets that need processing, e.g., jars exchanged, etc.; category 1 are specimens that are stored in the collection room.

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.

Category 3 are jars with metal lids that still need to be replaced with polypropylene lids with teflon liners (48 and 53 mm closures); category 2 are specimens that are on pallets; category 1 are jars (i.e., lots) which have been washed and cleaned on the outside, topped off if necessary or otherwise curated -- most of these specimens are contained in bailtop jars.

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.

Category 4 are specimens on pallets; category 3 are also located on pallets; category 2 are assorted phyla for which labels were not rewritten; category 1 are lots for which labels have been recopied

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.

Most lots contain an AHF number and no other locality information.
