* Owing to a misunderstanding, for which the editor is in no way responsible, the plate was allowed 
to go to press before certain necessary corrections had been made. The exopodite of the sixth leg (the 
penultimate thoracic appendage, the last being rudimentary) is not shown; and the structure of the 
remaining legs is obscure, each exopodite appearing to consist of a single ciliated joint directly articulated 
to the rest of the limb. This erroneous impression is conveyed by the complete masking of the basal 
portion of the endopodites by the proximal joints of the exopodites. The gills are shown in accurate 
detail in fig. I., p. 226.
