1863.] DR. BA.IRD ON NEW SPECIES OF WORMS. 107 



the elytra, are white, and a broad black line runs down the centre of 

 the dorsum throughout its whole length. The feet are encircled 

 with fine black circular lines. The elytra, eighteen pairs in number, 

 are oval, white, with black dots on the outer sides and centre, and 

 they are marked with a black semicircular patch on the inner edge. 

 They do not overlap each other, except near the head. On the body 

 of the animal they are wide apart, leaving the centre of the back ex- 

 posed. The under surface is of a bluish-black colour, with a narrow 

 white line running down the centre. The proboscis is large and 

 wrinkled, and the jaws are of a reddish-brown colour. The antennae 

 are five in number, the central one being nearly three times as long 

 as the external pair, and of a pure white colour ; the internal and 

 external pairs white, ringed with black. The feet are very prominent, 

 strong, rounded, conical, and armed with seven or eight stout brown 

 bristles. The second branch is extremely small, and sends oiF two 

 or three very small white setse. The superior cirrus is tolerably 

 long and sharp-pointed ; it is pedunculated, the peduncle being stout, 

 conical, and of a deep black colour. The inferior cirrus is short, 

 conical, and sharp-pointed. The last segment of the body is termi- 

 nated by two tolerably stout, but not long, cirri.

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 two 

 first 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 Fissurella cratitia. 



Hab. Esquimalt Harbour, Vancouver Island {Mus. Brit.). 



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,
