Lepidonotus frag ills. (Baird.) N. S. 



This species, owing to its brittle character, is in too 

 bad a state to describe accurately. It is about 2^ 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 

 Eisso, as occurring in the Mediterranean under the 

 name of Eamolpe fragilis. Hob. 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 

 | 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
