MARINE BIOLOGICAL STATION AT PORT ERIN. pa 
the structure of the Tubicolous Annelid, Terebella conchilega. 
. with a view of preparing an L.M.B.C. Memoir on the subject. 
Miss Stafford reports as follows on her work at Port Erin :— 
“ During my fortnight’s stay at Port Erin, from 5th April 
to 20th April, the aim of my work was twofold :— 
1. To examine, in their natural habitat and in tanks at 
the Biological Station, living specimens of 
Terebella conchilega. 
2. To preserve material of this species for further 
examination at Liverpool. 
“For collecting purposes the tides were very suitable. 
The small sandy tubes, often with fringed ends and standing 
up, or bending over, about 1 inch above the surface of the sand, 
indicated where Terebella could be found. It occurs between 
low and high water marks of ordinary tides, the zone just 
above low water mark being very densely crowded, although 
they are not nearly so thick just above low water mark of a 
spring-tide. Considerable care is necessary, while digging for 
Terebella, in order to remove the tube from the sand without 
damaging the worm and before it has time to withdraw to any 
great depth. 
“The tube-building habits of this worm have been worked 
out in great detail and described by Mr. A. T. Watson (Jowrn. 
R. Micro. Soc., 1916, pp. 253-256); but, from the point of 
view of general interest, I kept several worms, which I had 
removed from their tubes to shallow glass tanks, and made 
observations on their building habits on lines kindly suggested 
by Mr. Watson. I was fortunate enough to be able to see many 
of the wonderful actions, which he has described, and was 
struck with the remarkable activity exhibited. 
“With regard to preparations for preserving material, 
it was first necessary to remove the worms from their tubes 
and keep them for two or three days before fixing them in 
order to make certain that all sand had been voided from the
