Next we examined an interesting phyllodocid 
of the genus Eteone from a Bight’98 station in 
San Diego Bay that Ron Velarde brought to the 
meeting. It was from 3.3 m depth in sand. 
After comparing the specimen to Blake’s 
described species Eteone brigitteae 1992 in 
volume 4 of the MMS Atlas it seemed this 
animal most closely fit the related Eteone 
aestuarina Hartman-Shroder 1959 which was 
originally described from a shallow water 
estuarine habitat in El Salvador. So, perhaps 
another introduced species. However, without 
being able to compare this animal against the 
type it was decided by SCAMIT members to 
call the specimen Eteone cf. aestuarina for 
now. 
We also examined another phyllodocid of 
Ron’s from a sandy habitat in 171 ft from San 
Diego’s ITP survey station 1-7. There were 3 
specimens total. They belong to the genus 
Protomystides. Most species described from 
this genus come from the deep sea and 
hydrothermal vents. There are very few 
described from California. In volume 4 of the 
MMS Atlas Blake includes one of his species 
Protomystides mariaensis described by him in 
1992. These 3 animals don’t fit that 
description. Although this hasn’t been seen in 
any Bight’98 stations yet it may turn up so a 
voucher sheet will be forthcoming referring to 
the animal as Protomystides sp SD1. 
After lunch we examined another one of Tom 
Parker’s provisionals, an unusual Glycera from 
station 2490 (75m) west of San Miguel Island. 
Initially Tom was unable to see the dorsal 
ramus of the parapodia but finally did 
determine, after several dissections, it was 
biramous. The dorsal ramus was just very 
small. The specimen had a single large pointed 
presetal lobe with the postsetal lobe a 
minimum size to completely absent. The 
ventral cirri were large and pointed with the 
dorsal cirri up on the body wall. The 
proboscideal organs were of 2 kinds, both 
smooth walled types, most numerous were long 
and thin ones, with fewer shorter thicker ones. 
The most conspicuous character was the very 
large shafts of the compound setae. None of 
these diagnostic features seemed to fit any of 
the locally described Glycera so this was left as 
Glycera sp LAI. 
Another of Tom’s provisionals was a maldanid, 
Rhodine sp LAI. It was in two pieces, one 
included the prostomium and the other the 
pygidium. The head end was reduced in size 
and seemed to have been regenerated. The 
members present, after examining this 
specimen, concluded the prostomium and the 
pygidium were from different animals. So it 
was left as Rhodine sp. 
The last provisional of Tom Parker’s that we 
examined at the meeting was a Lacydonia from 
station 2491 (95m) west of San Miguel Island. 
The specimen had two large eyes and 5 
antennae. There were pigment granules on the 
parapodia and pigment on the pygidium. Only 
one species has been described off California, 
Lacydonia hampsoni by Blake in volume 4 of 
the MMS Atlas, but it was found in very deep 
water, 985-1990m. Tom’s specimen actually 
more closely matched Lacydonia miranda 
except that this species was originally 
described from the Mediterranean and had 
been reported from all over Europe and even 
one report (Gathof 1984) from shallow water 
off western Llorida. It seemed likely that there 
might be several species going by the same 
name, Lacydonia miranda , because the several 
authors described different parapodial 
structures with some even lacking eyes and 
median antenna. The San Diego lab had 
reported 2 specimens of Lacydonia from off 
the mouth of San Diego Bay from 62 ft station 
1-34 (not a Bight 4 98 station). They were 
smaller than Tom’s specimen and not as 
pigmented, but they did have eyes. Lor now 
Tom’s provisional will be referred to as 
Lacydonia sp LAI.
