found on the South Coast of Devonshire. 83 
purple streak down the middle of the back : segments about 
seventy-four, furnished with as many peduncles and fasciculi on 
each side, and a short filamentous appendage to each peduncle : 
the fore part of the head is divided into three lobes, the two outer 
ones are largest, and the end of each is furnished with a small tuber- 
cle, which seems capable of some extension, and possibly may be 
wholly retractile ; the middle lobe terminates in two short feelers ; 
at the base of each of the outer lobes are four others, very similar : 
the mouth is placed beneath, and is capable of being protruded, 
armed with two dark coloured fangs ; but these are not visible 
when the mouth is contracted : at the base of the protruded 
part of the mouth is a circle of numerous minute black spots : 
round the fangs are five other series of the same, and two at the 
upper part : at the extremity of the posterior end are two fila- 
ments : the whole under part of the animal is paler than the 
upper, and when examined by a lens exhibits a beautiful pearly 
gloss. 
Length, five or six inches ; diameter, about one-eighth of an inch. 
Inhabits the same place as the last, and is equally rare. 
Nereis lineata. 
Body slender, depressed, } T ellow, with numerous fine purple 
spots disposed in six lines ; two along the back, and two along

six; two pairs in front scarce longer than the tubercles, and one 
on each side the head of a superior length : posterior end fur- 
nished with two short appendages. 
Length, one inch and a half. 
Taken by dredging in deep water : rare.
