Lepidonotus fragilis. (Baird.) N.S. 
This species, owing to its brittle character, is in too 
bad a state to describe accurately. It is about 24 or 3 
inches long, and is rather narrow. The scales or elytra 
appear to be very thin and membranous; but as they 
are deciduous it is difficult to ascertain the number, 
especially as the worm is broken into several pieces. 
The superior cirri are stout and club-shaped at the tip. 
There appear to be no ventral cirri on the feet, and the 
superior cirri become nearly obsolete on the lower half 
of the body. 
It was found by Mr. Lord, adhering to a star-fish ; 
‘but,’ he says, ‘it is next to impossible to obtain one 
perfect, as they break themselves to pieces on the 
slightest touch, or however carefully killed.’ In this 
respect it resembles a species of Annelide belonging to 
the group of vermiform Aphrodisians, described by 
Risso, as occurring in the Mediterranean under the 
name of Humolpe fragilis—Hab. Esquimalt Harbour, 
Vancouver Island. (Brit. Mus. Col.) 
Nereis foliata. (Baird.) N.S. 
This Nereid is of a dark grey colour above, and of a 
lighter hue underneath, somewhat iridescent It is 15 
inches in length, and at the broadest part is “about 
4 an inch in breadth. It tapers gradually towards the 
tail, which terminates in two short, blunt, caudal 
styles. The first or occipital segment of the body is 
about twice the length of the second. The tentacular 
cirri are unequal, and vary in length; in the largest 
and best developed specimen the longest are only about
