concluded that this specimen was probably a 
small Aricidea (Acmira) cerruti, but without 
the median antenna for confirmation, Kelvin 
will leave the identification as A(A.) cf cerruti. 
Larry and Tony both brought in specimens of 
Chone sp SD 1 from El Segundo and Bight 
station 2453. Kathy Langan confirmed the 
identification; this species had also been found 
at some Tijuana River stations as well as 
monitoring stations offshore of San Francisco. 
See San Diego voucher sheet from February 
13,1998. 
We then examined a flabelligerid from San 
Diego Bay brought in by Rick Rowe. It was 
collected at station 2231 at 13 meters depth. It 
was sand encrusted, and anteriorly, it had a row 
of 4 small papillae across the dorsum. The 
setae were very similar to Piromis sp A fide 
Harris 1985. It was decided to call these 
Piromis sp SD 1. 
Continuing with another species from San 
Diego Bay, Kathy Langan showed us some 
specimens of Scolelepis. These keyed out to S. 
texana in Blake 1996 and keyed out to S. sp SD 
1 in Lovell’s and Pasko’s spionid key of 
November 1995. This species had shown up at 
several stations in San Diego Bay. There were 
a few character differences between these 
specimens and the description of S. texana , so 
it was decided to call these S. sp SD 1 since 
they more closely matched that description. 
Kathy also showed us some Dipolydora from 
stations 2472 (Santa Cruz Island, 25 m depth), 
2211 (Orange County Sanitation District, 41 m 
depth), and station 2493 (Santa Cruz Island, 44 
m depth). These specimens were similar to D. 
bidentata but differed in some significant 
characters. The branchiae started on setiger 9 
instead of setiger 8 for D. bidentata. The 
posterior hooded hooks were bidentate in these 
specimens in contrast to the posterior 
unidentate hooded hooks in D. bidentata. 
Also, no needle packets were seen in these 
specimens. However, with alcian blue stain, 
we observed some structures in the posterior of 
2 worms that at first glance resembled needle 
packets. The structures were lobes containing 
a few to several pointed spines. Some of the 
points extended beyond the ends of the lobes. 
A voucher sheet will be prepared for this new 
species, Dipolydora sp SD 1. 
Tony brought a specimen of Nereiphylla from 
station 2404 which turned out to be 
Nereiphylla sp 3 fide Harris ( ^Nereiphylla sp 
SD 1). 
Ron brought a mystery phyllodocid from Santa 
Cruz Island station 2518, 112 m depth. He 
identified it as Eulalia ?. It had pigment circles 
around each segmental line on the dorsum. 
There was also pigment on the bases of the 
parapodia. No one had seen anything similar 
to this specimen before, so it remained as 
Eulalia ? for the time being. 
We could not put off addressing the cirratulids 
any longer, so Rick took the floor and started 
off with 2 specimens of Protocirrineris from 
San Diego Bay station 2226. Rick compared 2 
different specimens. They were similar in that 
they had no methyl green staining pattern, no 
spines, and did have multiple cirri on setigers 3 
and 4. One specimen was similar to P. sp A in 
that it had compressed segments, and the other 
specimen had longer segments that were not 
crowded. However, Protocirrineris sp A is 
usually found at deeper stations. Rick is 
looking for more specimens and for the time 
being will refer to these specimens as P. sp SD 
1 . 
There were several new species of 
Monticellina that were discovered in the 
Bight’98 study. Rick reviewed several 
provisional species that he had encountered. 
Most of these had distinguishing methyl green 
staining patterns. The first was Monticellina sp 
SD 2 which is similar to M. elongata. This 
species was found in 80 m depth at the Channel 
Islands. Rick next described M. sp SD 4 from 
San Diego Bay and noted the differences 
between it and Blake’s M. serratiseta. It had: 
1) a light dorsal methyl green stain on the
