poses. Details of these appendages will heeome mereasinely necessary as further 
new species are discovered haying body sculpture similar to that of one or other 
of the forms already recorded. 
Apart from the proportions of the joints of the second peraeopod, the relative 
lengths, character. and position—terminal or subterminal—of the distal setae or 
spines of the dactvlus are worthy of notice. 
Reference to the figures of the various authors will show that the differences 
in the third maxilliped are more apparent than would seem to be indicated in 
the key to the species. The third to fifth peraeopods are of negligible taxonomic 
interest in this genus, as generally they differ little, while Hansen (1920, p. 44) 
considers that too much reliance cannot be placed upon the proportions of the 
uropods and their non-articulated armature.
