136 Mr. A. O. Walker on tlie Lysianassides 



Lysianassa longicornis (10). 



One specimen in good condition and unmutilated. This is 

 certainly not Lucas's species. By immersion in glycerine 

 the first gnathopods could be plainly seen, with the details of 

 the hand and wrist clearly defined. The hand is subchelate 

 and corresponds exactly with that of Orchomene Bafei, G. O. 

 Sars, when compared with Sars's figures in his beautiful 

 work on the Norwegian Amphipoda and with Dr. Norman's 

 mounted specimens. It is needless to add that it is 

 entirely different from that figured in Bate and AVestwood's 

 plate. It is certain that the mouth-organs figured could not 

 have been taken from the specimen in the tube, which is, as 

 I have said, unmutilated ; and it therefore seems probable 

 that the authors dissected a true L. longicornis^ Lucas, 

 figuring its mouth-organs and gnathopod, while they figured 

 the entire animal and the tail from the specimen in the tube, 

 which I have no doubt is a male Orchomene Baiei, as long 

 since suggested by G. 0. Sars *. At the same time Mr. 

 Stebbing t was fully justified in questioning this in view of 

 the form of the first gnathopod figured by Bate and West- 

 wood. 



Anonyx longicornis^ Bate. Not in the collection. 

 = Lepidepecrenm longicornis. 



Anonyx Edwardsi (15). 



The tube so labelled contains several specimens of Orcho- 

 wenella ciliafa, 8ais, the largest of which does not exceed 

 4{ millim. in lengthy and no other species. The measure- 

 ment given by Bate and Westwood is -jV inch, but the two 

 lines indicating the length given above the figure are respec- 

 tively this length (or, say, 7^ millim.) and 20 millim. It is 

 therefore tolerably certain that the specimens now in the tube 

 are not the same as that described and figured. This has 

 been referred by G. O. Sars to Orchomene Datei ? , at which 

 it may stand. 



Anonyx ohesnsj Bate (16). 



One specimen, the details of which could not be made out 

 without dissection.
