  • "-- Description of the cephalopods, gasteropods and lamellibranchiata."
  • "The cephalopods of the system are all of an obsolete type, that disappeared myriads of ages ago, -- a remark which, with the exceptions just intimated, and perhaps one or two others, applies equally to its brachipods; but of at least two of its intermediate families, -- the gasteropoda and lamellibranchiata, -- several of the forms resemble those of recent shells of the temperate latitudes."
