TAXONOMIC INTERCALIBRATION NEWSLETTER May, 1932 Next Scheduled Meeting: PI ace: Topic Taxonomic Group: Number 2 June 14, 1982 at 9:30 a.m. Marine Biological Consultants 9^7 Newhal1 Street Costa Mesa, California 92627 Amphinomidae, Euphrosinidae, Phyllodocidae MINUTES FROM MAY 17, 1982 Name Fourteen different names with accompanying acronyms were suggested. Because there were so many, it was decided to vote for a name by ballot and talley the results at the June meeting. One ballot is enclosed in this Newsletter. Please bring it to the next meeting or mail it to Ann Martin by June 11. Make additional copies of the ballot for each member of your Company. Dues Unfortunately dues are going to be cfrarged. The dues will help defray costs incurred for storing the reference collection, paper, postage, and other unforeseen expenses. Dues will be $5.00 per year beginning June, 1982. This amount will be adjusted after six months if it is insufficient. Dues will be collected at the June meeting. For those unable to attend the meeting, dues can be mailed to.Ann Martin and a receipt will be mailed back. Specimen Exchange. Several points concerning the specimen exchange were brought out that will help. - Participants should be responsible for getting their specimens to the meeting, either in person or by mail. - Mark the specimens sequentially to prevent mixing of different groups. - Bring the voucher specimens to meeting to check them with ones from the specimen exchange. - When deciding what species to select for the specimen exchange, first call Tony Phillips, (213) 322-3131 extension 269, and tell him what you plan to bring in. This should limit the number of duplicate specimens. For each species from the specimen exchange, fill out a voucher sheet (an example is enclosed). The voucher sheets from all participants will be consolidated into one sheet per species and be distributed via the Newsletter. Voucher sheets for the scale worms will be given in the next Newsletter along with voucher sheets from the June meeting. Reference Collection Sue Williams was elected to maintain the reference collection. The collection will be kept at the Allan Hancock Foundation. The Foundation has funds available for supplies for the reference collection. Also several sanitation agencies have offered to contribute supplies. Sue will be taking individuals for the reference collection from the specimen exchange. Please set aside the best individuals for her so she can select a good reference specimen. Quality Assurance Quality Assurance was discussed briefly. Most efforts have been concentrated on sorting. Generally 5 % of the samples are resorted. People using resorting and reidentifying procedures have bound them beneficial in monitoring the quality of work. Guidelines for quality assurance and identification methodology will be developed eventually. Charter No progress on the Charter had been made. Don Mauer is preparing a draft for the Charter Committee to review at the June meeting. - 2 - BALLOT SHEET FOR THE NAME Select three names.

Setigers 3 £ 4 with shorter notosetae and closely spaced (like IS?) Mvriochele oculata from Bering Sea: 1. Has little red eyespots; nuchal pigmentation more evident in fresh material or material that has not been stored in denatured alcohol. 2. Prostomium with a "flat top" 3. Tube more cohesive than that of Myriochela sp M, but not as organized as M. gracilis 1 tube. 4. First four setigers fairly evenly spaced, much as the illustration in Uschakov, 1955.

TAXONOMIC INTERCALIBRATION POLYCHAETA AHF Species 1: Hemipodus californiensis Hartman, 1938 Distinguishing Characters: 1. Proboscideal organs appear to be of one kind: conical, with numerous ridges- giving the appearance of a serrate margin (paratype examined) 2• Parapodia reduced, compared to H. borealis . Postsetal lobe broadly truncate and slightly pointed (H. borealis is broadly rounded) SEE ILLUSTRATIONS BELOW, FROM HARTMAN, 1938 *3. Ventral cirrus retains the same shape and relative size throughout the body length and may even appear to be smaller in the posterior region. Fig. 1. Hemipodus borealis.

T TAXONOMIC INTERCALIBRATION POLYCHAETA AHF Species 2: Hemipodus borealis Johnson, 1901 Distinguishing Characters: 1. Proboscideal organs are of two kinds: a. The more numerous are tall, slender, with faint ridges, which are especially evident in side view b. The less numerous organs are shorter, thicker, and have ridges 2. Parapodia are more elongate than.those of H. californiensis. The postsetal lobe is broadly rounded. SEE ILLUSTRATION ON H.CALIFORNIENSIS PAGE. - *3. The ventral cirri change shape in posterior segments, becoming triangular (long and pointed). The ventral cirrus is cordate in the anterior region. It is possible to identify a juvenile Hemipodus as long as the animal is complete. The difference in shape m the ventral cirrus is evident in the smaller specimens. HABITAT: Sandy beaches with organic enrichment (i.e. it likes a bit of muck). Found commonly on Santa Catalina Island (Isthmus S # Catalina Harbor), Mugu Lagoon. Occasionally at Corona del Mar.
