Hist., Ser. 7 (1899), Vol III, p. 240) in which he showed 
that the genus Podocerus, Leach, belonged to a different 
family, and that Leach’s genus /assa must be adopted 
in its place for the above species. He also proposed 
Parajassa for Leach’s Jassa pelagica, previously known 
as Podocerus capillatus, Rathke, Janassa variegata, 
Boeck, &e:, &¢.- In’ Ann’ and Mag: N.Y, Ser: 7, 
Vol. XVI (1905), p. 83 (Note), Canon Norman calls 
attention to the fact that Bruzelius in 1859 had restricted 
the use of /assa to the species with a rudimentary 
secondary appendage in the upper antennez, so that it 
could not be used for Pulchella, Leach (= falcata, 
Mont.), which has a quite distinct appendage. He 
therefore proposed a new genus Bruzeliella for this last, 
Jassa, instead of Parajassa, being used for pelagica, 
Leach, and, in deference to Canon Norman’s high 
authority, I adopted his genus in my Indian Ocean 
amphipoda. Mr. Stebbing on the appearance of my 
paper wrote to me as follows:—‘‘ Leach in 1814 
‘instituted Jassa for J. pulchella, J. pelagica, and 
“probably J. falcata (Montagu). In 1816 he republished 
‘‘ Jassa, assigning to it the single species J. pulchella. 
‘“How could Bruzelius in 1859 have a right to restrict 
‘“ Jassa to pelagica, when Leach himself restricted it to 
‘“nulchella?’’ Mr. Stebbing’s argument convinced me, 
and I have gladly adopted the older and shorter name. 
As to the question of pulchella, Leach, or falcata 
(Mont.), Mr. Stebbing’s reasons for the former will be 
found in Ann. and Mag: N.H Ser. 7; Volo LET (1899); 
p. 239, and the case for falcata at p. 395 of the same 
volume. To the remarks there I may add (1) that if 
Montagu’s Cancer (Gammarus) falcatus is not our 
species, it is hard to say what it is;* and (2) that the 
* Mrs. Sexton, who has examined Montagu’s type specimen at 
the British Museum, informs me that ‘‘it is unquestionably this 
species.’’
