 among the roots of eel grass. It is usually pale red, with bands ot buoht u'd aiound 

 the swollen parts of the segments, but it is most readily 

 recognized by the collar on the fifth ring and the peculiar 

 I'uimel appended to the tail. There still remain a. host of 

 curious genera, Sttniaspis, 3IaHayunJcia, I'olydura, (Jirrul-

 a trio of brief allusions ; first, to tlie lug-worm, Arenicola

 of rock-weed (T^iiciis) thrown uj) from shallow water'. Each individual worm is 

 as pretty and delicate as any species of Scrpula, aii<l, like the members of tliat genus,
