Dr. W. Baird on new Species of Worms. 97 
2. Leprponotus Lorot, Baird. 
This species is about 3 inches long, and rather more than one-third 
of an inch in diameter at the broadest part of the body. It tapers 
gradually from the head to the tail, which is only about ;2,ths of an 
inch broad. The colour is of a light brown, a broad line of a much 
darker brown running along the whole length of the centre of the 
back. On the under surface, a groove runs down the centre of the 
body throughout its whole length. The elytra are thirty-five pairs 
in number, thin, membranous, and of a light-brown colour. The first 
two overlap each other slightly in the middle; but, for the rest of 
its length, the centre of the back is uncovered. The antenne are 
five in number, the central one short, of much the same length as 
the internal ones; the two external the longest, white, with a bright 
black ring round the upper part, but leaving the point white, which 
is acute at the apex. The feet are tolerably stout, and the two divi- 
sions are both furnished with sharp, but curved, pointed bristles. 
The superior cirri are white and of a moderate length; the inferior 
ones very short. 
A good many specimens of this species were taken, and they were 
all found nestling under the shell, and occasionally coiling themselves 
under the foot, of the animal of Fissurella cratitia.

3. Leprponotus GruBet, Baird. 
This species is about 2 inches long, and } an inch broad. The 
body underneath is of a uniform brown colour; above it is whitish, 
mottled with black. The elytra are eighteen pairs in number, nearly 
round, rough, with small tubercles, edged by a slightly raised margin, 
and mottled with black and white. They do not meet each other in 
the centre, but leave a portion of the back uncovered. The superior 
cirri are rather long, blunt-pointed, pedunculated, marked with a 
black spot at the base, where they issue from the peduncle, and are 
ringed with black a little distance from the extremity. The inferior 
cirri are short and acute-pointed. The feet are broad, and the 
bristles of both branches are stout, of a bright brown colour, and 
toothed on one edge near the extremity. The antenne are five in 
number, and are all short and nearly of equal length.

4. LEPIDONOTUS FRAGILIS, Baird. 
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 membra- 
nous; but as they are deciduous, it is difficult to ascertain the num- 
ber, especially as the worm is broken into several pieces. The supe- 
rior 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 starfish ; “but,” he says, 
“it is next to impossible to obtain one perfect, as they break them-
