Vol. 31 Nos. 5-6 
Stylostomum lentum - small, short frontal tentacles (more knob-like) with tentacular eyes; large 
tubular pharynx in anterior third of body; cluster of cerebral eyes; color beige to bright red. 
Enchiridium punctatum - beige with tiny black spots; no frontal tentacles; anterior tubular 
pharynx; marginal eyes multiple layers anteriorly, thinning to one layer posteriorly; marginal eyes 
visible ventrally rather than from dorsal aspect. 
Prosthiostomum latocelis - frontal eyes extending broadly posteriorly and laterally to cerebral eye 
region but anterior to pharynx. 
Prosthiostomum multicelis - found more often from scrapings, etc.; marginal eyes more tightly 
bound (than P. latocelis) to anterior margin, extending only to 1/3 of body; cerebral eyes present; 
tubular pharynx. 
Turbellaria sp A (= sp 27 of Ljubenkov) - note size of cerebral eyes relative to A. langi. 
Turbellaria sp B - bays and estuaries towards fresh water; 1 pair of large eyes with 2-3 pairs of 
smaller cerebral eyes; fairly thick animal, frequently w/ curled margins. 
Turbellaria sp C (= Leptoplanidae sp SD2 Lilly-Pasko); elongate, thin species, up to 15 mm long, 
with two pairs of round eyes situated anteriorly, the first slightly larger than the second. 
GENERAL COMMENT - eyes develop differentially with age, so smaller specimens have 
fewer (or absent) cerebral eyes. It is important to distinguish between two types of anterior eyes: 
cerebral and frontal. Frontal eyes reach the anterior margin of the head and are typically anterior 
to tentacles; whereas cerebral eyes are more clumped and can extend posteriorly in a loosely 
structured group. Tony also noted that eye patterns may be (likely are) inconsistent between 
species within a Family because Family-Generic distinctions are made by internal morphology, 
not external (generally). 
11 FEBRUARY 2013, POLYCHAETES, NHMLAC 
Attendance: Ron Velarde, Peter Vroom, Kathy Eangan, Veronica Rodriguez-Villanueva, 
Ricardo Martinez, Matthew Nelson, CSD; Kelvin Barwick, Rob Gamber, OCSD; Eeslie Harris, 
NHMLAC; Tony Phillips, consultant; Chip Barrett, EcoAnalysts; Larry Lovell, Cheryl Brantley, 
Bill Furlong, FACSD; Dot Norris, CCSF/PUC; Greg Fyon, CFAEMD. 
Farry Fovell opened the meeting with introductions. Next was a discussion of upcoming 
meetings. Fiterature review, and shallow and deep water species review, prior to Bight ’ 13 were 
suggested topics. The following dates, subjects, and locations have been scheduled: March 11, 
Echinoderms at CSD, Megan Filly meeting lead; April 15, Misc Phyla at Dancing Coyote Ranch, 
John Fjubenkov meeting lead; May 13, Mollusks at OCSD, Kelvin Barwick meeting lead; June 
10 Arthropoda at CSD, Dean Pasko meeting lead; Polychaete meeting in June TBD. 
The polychaete meeting was a Bight ’ 13 preparation led by Eeslie Harris and others. The 
taxonomy portion of the meeting started with a review of papers distributed electronically by 
Eeslie. There were many newly published papers she had gathered for sharing and discussion. 
Eeslie next led a discussion of her provisional species recently reported in the SCB. 
Mediomastus sp 6 Harris - staining difference, larger species. Eeslie only sees them as larger 
individuals. There is a staining patch on the head. It is reported from South SD Bay and Hyperion 
SMB samples. Copies of her drawings were distributed.
