SixcK (lie liiue when it was first noticcMl by rallas, in 

 I7(i(i, as " alia Limibiici species marini tota atva," the 

 Nemertean now known as Lim-iis (/esscrens/M (which we 

 choose as our type) has been the recipient of no less than 

 10 generic and 1-5 specific names associated together in 

 various perniirtations and combinations. Our knoAvledge 

 of the habits and anatomy of the worm are chiefly due to 

 """M'Intosh, Barrois, Hubrecht, Uudemans, and ^[ont- 

 o-omerv. Yaivine- in size from about (i-2U cm., it is one 

 of the commonest Nemerteans of our shores, occurring 

 abundantly, and frequently in tangled masses, under 

 stones between tideniarks and in the laminarian region.
