 lum ; tubes testaceous, very numerous, cylindrical, subangu- 

 lar, straight, waved, crowded, fixed by their base and open 

 at the summit ; aperture orbicular, terminating on the side 

 by a spatulous tongue ; operculum orbicular, with from five 

 to nine testaceous pieces above, and all attached to one side.

Gen. 3. VERMILIA, Lam. Serpula, Lin. 



Body tubicular, elongated, narrowed towards the posterior part, 

 and furnished towards the upper part with a testaceous orbi- 

 cular simple operculum ; tube testaceous, cylindrical, narrow- 

 ed posteriorly, more or less twisted, and fixed by the side to 

 marine bodies ; aperture round, and the margin with often 

 from one to three teeth. 



V. triquetra, Lam. Shell creeping, flexuose, and three-sided ; ca- 

 rina of the back simple. Inhabits shores of Europe and Ameri- 

 ca, on stones and shells. B. Brown's Illust. pi. 2, fig, 1, 5.

Gen. 4. SERPULA, Lam. Lin. 



Body tubicular, elongated, slightly depressed, and attenuated 

 posteriorly, with numerous narrow segments ; small bundles 

 of subulate bristles in one row on each side, and hooked bris- 

 tles ; branchiae terminal, fan-shaped, deeply cleft into fine 

 digitations, pinnated or plumose ; mouth terminal, situate 

 between the branchiae, and surmounted by a pedicellate fun- 

 nel or club shaped operculum. Tube solid, calcareous, ir- 

 regularly twisted, grouped or solitary, fixed, with the opening 

 rounded and terminal. 



This genus is numerous in species, of which the greater part are found in the seas 

 of Europe. The tubes are always solid, homogeneous, calcareous, fixed on marine 

 bodies, sometimes by their posterior extremity only, and sometimes in their whole 

 length. These tubes are waved, irregular, and tortuous, and are often found twisted 

 in groups together. They are only open at the anterior extremity. The animal of 

 the Serpulas is very con tractile, has red blood, and feeds on aquatic animalcules, which 

 it seizes by means of its branchiae.
