22 Mr. Monracu’s Description of several new or rare Animals, 
fascicles, and in some points of view appearing like a single hair; 
above this issues a cirrus changeable in shape, but never longer 
than the peduncle, independent of the fasciculus: tentacula 
seven, the middle one largest, and placed in the centre of the 
= forehead between the eyes, somewhat erect, and appears to be 
= jointed: eyes four, black, the hindmost pair smallest, and 
not visible on the upper part; the others are large, and most 
conspicuous beneath: along the back are seven cordiform, equi- 
distant yellow spots, the ground colour white. 
Length about an inch. Rare. 
This is somewhat like Nereis corniculata of Muller, but the 
want of the bifid tentacula makes it distinct.

Body long, cylindric, covered with minute papille of a yel- 
lowish white colour, marked with small spots of red-orange closely 
disposed, and in many parts confluent; posterior end tinged 
with green: tentacula twelve, short, dividing at their tips into 
four obtuse branches of a pale colour. 
Length when extended between three and four inches. - 
This rare species is capable of great contraction, and probably 
multiplies by natural divisions, as it separates without violence - 
into an indefinite number of pieces : this is effected by muscular 
stricture, which forms ligatures and separates portions into glo- 
bular pieces; sometimes two or three of these ligatures are 
formed. together, and as many separations ensue, provided the
