5, Nereis nirsuta.—Plate XXXVI. Fig. 10.

minating by two knobs. Head with two articulated flexible antenne,

Figs. 12, 13, 14, 15. 
This animal is probably allied to the Nereis, and may perhaps prove 
an intermediate link to Amphitrite. This is only a conjecture, how- 
ever, for it may be found something quite different, and only the larve 
of some more perfect creature. ‘Therefore I introduce it here with great 
diffidence. 
Length towards two lines ; breadth under half a line. An indenta- 
tion seems to distinguish the head from the rest, but the segments of 
the body are imperceptible, and the tail terminates in a fork. Ten- 
tacula two, fringed with bristles. Four stumps appear towards the an- 
terior, from which issue bristles half the length of the body. 
Colour to the eye white. 
This creature occurred among miscellaneous collections from the sea 
in May, and survived about a month.
