REPORT ON THE AMPHIPODA. 225 



Island a,' &c., I bad not seen any part of them when I prepared the ' List of Crustacea in 

 the British Museum.' " 

 The account of the upper antennae shows that White is wrong in allying his new genus to the 

 OrchestidsB ; in Boeck's opinion his own Soranifs may possibly be a synonym of White's 

 £j)M]}pipJioi-a. 



1848. Adams, Arthur, and White, Adam. 



The Zoology of tlie Voyage of H.M.S. " Samarang " ; under the command of 

 Captain Sir Edward Belcher, C.B., F.E.A.S., F.G.S., during the years 1843-1846. 

 Crustacea by Arthur Adams, F.L.S., and Adam White, F.L.S. London, 1848. 



On page 63 is given " Rhabdosoma, Adams 4' White. Oxyeephahis, M.-Edwards. We regret 

 that the state of the only specimen in the British Museum is such that we cannot give the 

 generic character witli that detail which we should wish. It is founded on the third species 

 of Professor Milne-Edwards, indeed Mr. White has the authority of that eminent Crustaceo- 

 logist that it is his very species ; it is so different from the Oxijrejihalus piscafm; M. 

 Edwards (Crust. III. p. 100 t. .30. f. 10), that we have traced the figure of Oxiiccphalu>i 

 piscator, and added it below that of the Oxycephalus armatus to show the difference. Some- 

 day it may be proved to be a sexual character, when of course our name will sink, but an 

 yet we know of no such discrepancies in the sexes of tliese Crustacea. 



" The head is as long as the rest of the body, and ends in a very long beak; from the state of our 

 specimen we cannot describe this, but indicate it on the plate from a drawing made at the 

 time of capture. The immense length of the body and beak would sufficiently mark this 

 generic form. The first two pairs of legs are shown in the figure, which must serve till we 

 can ijrocure further specimens, when we hope to give ample details of this very singular 

 crustacean, and to analyse its characters at length. It forms a singularly interesting link 

 between the AmjJliipoda and Lxmodipioda, uniting, as it were, the two ; we should like to 

 have this form examined particularly by Prof. M. Edwards or Dr. Kroyer.

 Crust. III. p. 101. pi. 30. f. 10, copied. (Tab. XIII. Fig. 8.) 



" The specimen described by Professor jNIihae Edwards was found by MM. (^uoy and Gaimard 

 in the Ocean between Amboina and Van Dieman's Land, and is now in the Paris Museum. 

 Ours was taken during a calm, floating on the surface of the South Atlantic Ocean." 



1848. Leydig, Franz. 



In his Treatise " Ueber Amphipoden und Isopoden," 1878, page 229, note 2, Leydig says that 

 he had already in 1848 described and figured the segmentation-process of Gammarus ; but 

 he does not say that the account was published, though this would seem to be implied by 

 the context. 



1848. Milne-Edward.s, H.

 dcs sciences naturelles. Troisieme Serie. Zoologie. Tome ncuvieme. Paris, 1848. 



This note, at page 398, records the finding of an amphipod, with a body 9 cm. long and 

 3 cm. high, by M. d'Orbigny, who took it from the stomach of a fish caught off Cape 

 Horn. Supposing it to be new, Milne- Edwards names it " Lysianassa Maycllanka." 



It has since been identified with Jlandt's Gammanis gri/Uus, and named Eurytencs yrylhis.
