Now in the first place it cannot be said from M. Sars” treatise 
of 1868 that in any of the species mentioned in that work two 
appendices were also to be found on the 5th pair of pleopods. It 
is only on the 2nd pair of pleopods of males that two appendices 
are always mentioned as being present; and this has been found 
to be the case moreover in the 
specimens examined by me. 
In the second place it seems 
to me as if the two appendices were 
attached (as shown in the adjoining 
MA eg figure) to å special joint (J). This
