singularity of its structure. The free margin is clouded and mottled 

 something like the shell, with brown, orange, black, and white, and 

 two or three series of short ciliated tentacula, which are not exactly 

 marginal, encircle the outer edge. Similar tentacula garnish the 

 thickened margin next the adhering part of the cloak, intermixed with 

 a few of much larger size placed at distant intervals ; and in this inner 

 series we find little black bead-like bodies placed at regular intervals, 

 glowing with the lustre of some precious stones. These beads are 

 very hard, iridescent, circular, nearly sessile, and, I think, cupped in 

 the centre ; but of their function no probable conjecture has been 

 offered. 



It win be observed from the table, that no species of Tubicolae is 

 found on our shore, — species which are more peculiarly organized for 

 burrowing in wood, clay, and stone ; yet our limestone rocks are per- 

 forated in every direction with thimble-like cavities, large enough to 

 admit a finger. These holes are the sole work of the Hiatella niffosa, 

 which has the wonderful property of excavating its cells in the rock by 

 the excretion probabl}' of an acid or solvent, the nature of which, 

 however, remains to be discovered.
