I have dedicated this species to the ibimder of the genus, to whose 

 courtesy and kindness I am indebted for an examination of the 

 specimens in the Museum of the Jardin des Plantes. I was not only 

 permitted to break open the secured covers to the l)ottles, for the 

 purpose of a closer examination of the t}-pical species, but wa.s en- 

 trusted with a valuable collection of imnamed specimens to bring to 

 England for more convenient study. It was amongst these latter 

 that I obtained the one I have now desciibed, and named in honour 

 of M. Milne-Edwards, the Professor of Entomology in the Jardin 

 des riantes at Paris. I have therefore been enabled to describe 

 the animal in more minute dctaQ than I otherwise could. More- 

 over I found within the incubatory pouch many young animals, 

 having apparently just quitted the eggs ; they were very small — 

 about J^th of an inch in length. The observation of a considerable 

 number has enabled me to state the following curious facts, which 

 must have some influence in the classification of this division of the 

 Amphipoda. 



You-iuj. — The eyes are small, i-ound, and not very distant. The 

 superior antenna), instead of being like those of the adult, are 

 foi-med of seven articulations, taking the first three joints to be 

 the peduncle : the first is moderately long ; the second about half 

 the length of the first ; the third about half that of the second 

 and narrower also ; while those that form the flagellum consist of 

 four that gradually diminish in length and diameter to the apex, 

 which is tipped -with foiu' robust hairs. The inferior pair of an- 

 tenna) are very minute indeed, and consist of a single joint, 

 longer than broad and tipped with two hairs : this is situated be- 

 hind and beneath the superior. The appendages of the mouth arc 

 very immature. The gnathopoda arc imi^erfectly developed ; all 

 the joints but the last three are subequal and nearly as broad as 

 long ; the last is much narrower, cylindrical, straight, and obtuse. 

 The first two pairs of pereiopoda are uniform ; the cari)us is slightly 

 more robust than the propodos, gradually tajjering to the extre- 

 mity, which is posteriorly tipped with a single stifi' spine on each 

 side of the articulation with the dactylos ; dactylos short, sharp, and
