Remarks — As manv earlier workers have 



noted, L. ninetta and L. eollaris differ only in 

 the shape of the eyes which are reniform in 

 L. ninetta and oval in L. eollaris. Fauchald states 

 that the degree of ocular pigmentation is a 

 function of size and regards the two as synony- 

 mous. My observations on worms of many sizes 

 does not agree with this. Moreover L. eollaris 

 is restricted to subtropical or tropical waters 

 while L. )nnetta is cosmopolitan. For these rea- 

 sons I have retained L. eollaris as a subspecies 

 of L. ninetta.
