I can see nothing that induces me to change my opinion that this 

 genus of Latreille is but a damaged species of Proto. I have seen 

 man)' specimens, but could invariably identify them by other specific 

 charactei-s notwithstanding the absence of the two posterior pairs of 

 pereiopoda. Naupridia tristis of Yan Beneden appears to me to be 

 undoubtedly a damaged specimen of Proto pedata of Leach.
