ke showed me an Eschara from Plymouth with a partly 
upright more cylindrical Serpula with a rounded aperture, 
with the edge of which the operculum is placed immediately 
in contact. This organ may perhaps in future serve for 
distinguishing the genus or species. The Serpula which 
I have figured for S. triquetra in British Miscellany, tab. 
31, has a bell-shaped proboscis, with the addition of a 
peculiar tongue-like appendage, which gives some idea of 
a difference in these organs, but my figure is not properly 
triquetrous, but rather five-angled; and I conceive by the 
specimens I possess and have seen, that the Serpule may be 
divided much more than they have been. Ellis has a ver 
distinct figure of this instrument, tab. 38, fig. 2. 
I have since found in dry specimens of the recent Ser- 
pulz these parts preserved, when the specimens appear not 
to have been washed; and it may be recommended to those 
who collect these extraordinary productions, to preserve 
the animal in spirits, or if, when they protrude from the 
shell, a piece of paper be put under them, they will often 
remain very perfect. I preserved those figured in British 
_ Miscellany in this manner, and they may be kept thus 
many years. 
The Serpulz figured in this plate are attached to a frag- 
ment of the Strombus amplus of Brander, tab. 6, which is 
a rare Hampshire shell, and not before known in any other 
part of Great Britain.
