Hydrozoa over Corals; Crustacea over Insecta, and Amphipoda and
The same may be said of other Amphipoda, such as _Urothoe inostratus_,
As another instance of the practical application of the microscopical examination of the surface, I would refer to two species of Amphipoda, classed by Leach under the name of _Gammarus Locusta_, from his inability to assign them any separate specific characters.
Among Crustacea, there were the shells of Crabs and Lobsters, often bleached quite white high up the beach; Sea or Beach Fleas (Amphipoda); and the cases of the Horse-shoe Crab, or Saucepan Fish (Limulus Polyph; aemus), of which we saw many alive on the Bay side, where they feed pigs on them.
Cryptogamic vegetation would have the advantage over Phanerogamic; _Hydrozoa_ over Corals; _Crustacea_ over _Insecta_, and _Amphipoda_ and _Isopoda_ over the higher _Crustacea_; Cetaceans and
Amphipoda and Isopoda over the higher Crustacea; Cetaceans and Seals over the Primates; the civilization of the Esquimaux over that of the

Under the latter supposition its isolated occurrence is intelligible, whilst we cannot perceive why the Creator blessed just these few species with an apparatus which he found to be quite compatible with the "general plan of structure" of the Amphipoda, and yet denied it to others which live under the same external conditions, and equal them even in their extraordinary salacity.
Amphipoda, -- the primitive form of the heart was inherited unchanged, because any variations which might make their appearance were rather injurious than advantageous, and disappeared again immediately.
