Dr. W. Baird on new Species of Worms. 97 



2. Lepidonotus Lordi, 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 ^^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 antennae 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 Fissurelta cratitia.

3. Lepidonotus Grubei, 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 antennae 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 2| 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-
