ACTINOPODOUS HOLOTHUKIOIDEA. 77 



united to this species, but the pubhshed account of that form is 

 very meagre. I also think that all the forms mentioned are 

 closely related to //. monacaria TjEsson. In fact, there is ^XTy 

 little to distinguish them from the latter species : the only 

 points seem to be that the stone -canal is attached in //. dlf- 

 ficilis (or at least in //. captiva), while it is not in H. monacaria, 

 and that in the Atlantic where //. captiva is found, //. monacaria 

 has not been found.
