* 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.
