organism response. Many of the 14 sites tested 
within the Bay system showed toxicity in one 
or the other test. There was no significant 
influence of freshwater input into the Bay, 
either as rainfall or as riverine flow, on the 
toxicity of sediments. 
Not all sediment toxicity is anthropogenic. 
Bromophenols and other secondary metabolites 
of benthic infauna have been shown in the past 
to control settlement of competing larvae, or to 
keep areas around tubes or burrows free of 
spacial competitors. The hypothesis that 4- 
bromophenol exerted this influence by 
controlling the bacterial flora of the sediments 
was addressed by Lovell, Steward & Phillips 
(1999). Their results indicated that this 
hypothesis was unsupported; there was no 
significant effect of 4-bromophenol on 
sediment bacteria. 
OLD LITERATURE 
Dr. Michel Hendrickx of the Mazatlan Marine 
Institute has informed SCAMIT that he has 
copies of several of his large publications 
available free, and with a very modest shipping 
and handling cost. These include Hendrickx & 
Salgado-Barragan 1986, Hendrickx & Estrada 
Navarette 1996, and Hendrickx 1997. A new 
publication will also be available in the very 
near future; Hendrickx 1999. Interested parties 
should contact him via e-mail at 
michel@ola.icmyl.unam.mx. Handling is $5.00 
per volume + the cost of the shipping itself 
(varying with number of items desired, and 
nature of shipment method i.e. express mail, air 
mail etc.) Dr Hendrickx will be able to tell you 
how much it will be once you contact him. He 
can also be reached at 
michel @ mar.icmyl .unam .mx. 
All of the volumes are in Spanish, but are very 
well illustrated, have fine keys, and should be 
useful to anyone with the courage to attempt 
their use (Spanish speaking or no). 
An old friend has resurfaced. It was with 
considerable surprise and great gladness that an 
e-mail message was recently received from Dr. 
E. L. Bousfield announcing the resumption of 
publication of the journal Amphipacifica. It had 
made it through one and 3/4 volumes prior to 
his having to cease publication due to ill- 
health. He has weathered that crisis, and has 
decided to continue with publication where he 
left off. There were a number of manuscripts in 
progress at the time publication ceased 
(Volume 2 No. 3 was released in May of 1997). 
With the release of the final issue of Volume 2 
(expected June or July of 2000) these 
manuscripts should be addressed. Subscribers 
to Volume 2 will receive No. 4 without further 
charge. Others can purchase it for $10 (U.S.) or 
$12.50 (CAN). Subscription to the 4 issues of 
Volume III is available for $40 (U.S.) or $50 
(CAN) including surface mail delivery. 
Subscription requests and other 
correspondence should go to 
elbousf@magma.ca or Dr. E. L. Bousfield, 
Managing Editior, 1710-1275 Richmond Rd.,

MYTILUS REVISITED 
In the December 1999 NL the editor provided a 
brief commentary on the paper by Martel et al 
(1999) dealing with separation of juvenile 
mussels. In those comments I stated that they 
provide data on characters which would allow 
separation of juvenile Mytilus trossulus from 
Mytilus galloprovincialis . Member Dr. Jim 
Carlton had also read the paper, and reached 
different conclusions. He sent the following e- 
mail stating his case, and inviting reassessment 
on my part (which is provided below). I and 
other SCAMIT readers owe him a debt of 
gratitude for his correction. I would encourage 
other readers to take issue with statements or 
evaluations set out in the NL, both to correct 
misstatements, and to express differing 
opinion.
