VERMICULAR SERPULA.

The genus Serpula, confifting of a great number 
of fpecies of very different tizes and forms, is among 
the leaft regular of the teftaceous tribe; and the in¬ 
habiting animals appear of a very different caft from 
thofe of any other fhells. The fpecies here figured

agglutinated as it were, longitudinally, to the larger 
Ill ells.
