Revision of Amphipoda. 

 By the Rev. Thomas E. B. Stebbing, M.A., F.E.S. 



In the Ann. & Mag. Nat. Hist, for March 1899, at p. 241, a new 

 genus was defined for the reception of Coropliium excavatum, 

 Thomson, hut, by inadvertence, the name of the genus was omitted. 

 It is Paracorophium. On p. 239, 1. 15, for Darwinii (Bate) should 

 he read variegatus, Leach. 



This opportunity may be taken for announcing some other 

 changes which I consider necessary in the nomenclature of the 

 Amphipoda. Microdeutopus chelifer, Haswell, I propose to call 

 Microdeutopus Haswelli, and to transfer his Microdeutopus australis 

 to the genus Lemboides : the Autonoe lonc/idigitans of Bonnier to 

 the genus Lembos : Mceroides Thompsord, Walker, Mara crassipes, 

 Haswell, Mara deuiifcra, Haswell, Mcera Chiltoni, G. M. Thomson, 

 Parancvnia longimanus, Chilton, and Podoceropsis pahnata, Stebbing 

 and Robertson, all to the genus Gammaropsis. Leptocheirus pilosus, 

 Delia Valle, seems to be distinct from the species so-named by 

 Zaddach, and may be distinguished as Leptocheirus Dellavallei. 

 Biancolina algicola, Delia Valle, appears to be identical with 

 Am}'hithoe cuniculus, and will become Biancolina cunicidus. Mara 

 IJasivelli, G. M. Thomson, should, I think, be placed in Haswell's 

 genus Wyvillea, a genus about which, however, more precise infor- 

 mation is desirable. Podocerus dentex, Czerniavski, may, as Jassa 

 dentex, include in its synonymy Podocerus Herdmani, Walker, and 

 Podocerus odontonyx, Sars. The Siphoncecetes typicus described 

 by Delia Valle does not suit well with Kroyer's species, and deserves 

 the independent title of Siphoncecetes Dellavallei.

 Naturelle,' 1839-1849. By C. Davies Shebbokn and T. S. Palmeb. 



Careful collation of five copies of this ' Dictionnaire' shows that with 

 the exception of volume i. there was only one composition — that is 

 to say, if we take p. 100, for instance, the last word in every copy of 

 every volume is identical. There was a re-composition of volume i., for 

 one of us has examined an original copy in the U.S. Nat. Museum which 

 differs in that the " Discours " is paged in roman (i-ccxl) and p. 100 

 terminates with " qui est," two words towards the end of the article 

 "Acrodon." The other four copies of vol. i. which have been 

 examined by us are themselves alike, but differ in that they have a 

 new printer, some changes in authors, and a slightly different title- 

 page. It is quite possible that there were reprints of some of the 

 other volumes as they were exhausted, but there is nothing to 

 show, so far as our researches go, that any re-setting of the type 

 took place in any volume but volume i. 



Of the five sets examined, that of the U.S. Nat. Museum is the 

 most valuable, as, with the exception of vol. ii., it is apparently an 

 original issue. It belonged to Professor S. F. Baird. The Zoolo- 

 gical Society's copy shows what are probable reissues of the first 

 five volumes.
