When the young first hatch out,they are provided with a glassy nautiloid shell, a factwhich would indicate that at some remote period theywere, like most mollusks, provided with a shell. JEolis swims in an in-verted position, and is at times exceedingly active. It is very variable incoloring and in the number of cerata. GENUS Doris D. bilamellata. In Doris we find a quite different type of nudi-branch from that presented by the two genera Dendronotus and ^ one there were numerous branched cerata or doisal papillae, in theother many plain cerata, and in neither case were there any specialized. jEolis papillosa.
