The Amphipoda are distinguishable from the Isopoda at an early period in the egg by the different position of the embryo, the hinder extremity of which is bent downwards.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

Orchestia gryphus, from the sandy coast of Monchgut, alone presents a somewhat similar structure, but in a far less degree; elsewhere the form of the hand usual in the Amphipoda occurs.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

Less varied than that of the Stalk-eyed Crustacea is the mode of development of the Isopoda and Amphipoda, which Leach united in the section Edriophthalma, or Crustacea with sessile eyes.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

Considering this uniformity presented by the heart in the entire order of the Amphipoda, it cannot but seem very remarkable, that in the very next order of the Isopoda, we find it to be one of the most changeable organs.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

With regard to the Crabs, and also to the Isopoda and Amphipoda, we were led to the assumption that, about the period when these groups started from the common stem, a simplification of their process of development took place.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

The connexion of the "shell-glands" with the frontal horns has been recognised unmistakably in the larvae of Lepas, and indeed the resemblance of the frontal horns with the conical processes on the inferior antennae of the Amphipoda, is complete throughout.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

Scarcely less striking than the example of the air-breathing Crabs, is the behaviour of the heart in the great section Edriophthalma, which may advantageously be divided, after the example of Dana and Spence Bate, only into two orders, the Amphipoda and the Isopoda.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference

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.    From Wordnik.com.  [Cape Cod] Reference

This want of symmetry is something so unusual among the Amphipoda, and the structure of the clasp-forceps differs so much from what is seen elsewhere in this order, and agrees so closely in the five species, that one must unhesitatingly regard them as having sprung from common ancestors belonging to them alone among known species.    From Wordnik.com.  [Facts and Arguments for Darwin] Reference
