But it is plain that the earlier generations are overwhelmed, and theirsite obliterated, by those of later origin. The Lobularia is the prey of the Doris Hombergii, therefore obtain-ing recent specimens is of some consequence to the naturalist desiring thepreservation of that animal for permanent study. The food of the Doristribe can be seldom discovered. This product is commonly rooted on hard solid substances, thoughspecimens of smaller size grow also on the marine Alga? and the above all, the tube of the Ampkitrite ventilabrum, is most profuselyinvested by it in a single stratum and otherwise.

A small specimen once occurred onthe back of a living crab. Both white and orange Lobularia are very common in the Scotishseas. I have seen at least fifty specimens at once laying on NewhavenPier, which had been accidentally brought up by lines and dredges. Plate XLII. Fig. 1. Lobularia displayed in vigour. 2.
