On the tubes of Lanice conchilega void. Terebella (S.), Ehlers (2), 
pp. 66-74, & 96-99, pi. i. figs. 19 & 20. Ehlers, who observed living 
specimens of L. conchilega making their tubes, at last convinced himself 
that the ramifications on the upper margin of the tube of these species, 
and of T. Jlabelliim , are secreted by the worm, and are not a sponge 
A ulorliipis'^). Eis(?n (5), who descrifies and figures tubes similar to 
those of T. artifex (S.), from Norway and the Azores, under the name of 
T. palmata, has arrived at the same results.
