longer than the palpi, clubbed at extremity, and ringed with black 

 at the base and at a short distance from the point. The back is 

 partially uncovered by the elytra, and is marked by a broad blotch 

 of black in the centre of each segmeat, striated or as it were 

 wrinkled across and marked with fainter blotches of a dark colour. 

 The under surface of the body is of a uniform brownish colour. 

 The elytra are 18 pairs in number, are all nearly round, rough 

 on the upper surface with small tubercles, edged by a raised mar-, 

 gin, and mottled with black and white. They are smallest at the 

 anterior extremity. The dorsal cirri are clubbed and white at 

 extremity, about equal in length to the feet and bristles ; they 

 are pedunculated, and marked with a black spot at the base where 

 they issue from the peduncles, and are ringed with black at a 

 short distance from the point. The inferior cirri are short, and 

 acute at the point. The feet are stout, broad, and biramous. The 

 bristles of ventral branch are disposed in two fascicles, are of a 

 bright yellowish-brown colour, and are all similar in structure. 

 They are uncinate at the point, and at a short distance from it 

 are strongly serrated for a short way down. The dorsal branch 

 of the foot is small, and the bristles of that branch are very short 

 and serrated across for the upper two-thirds of their length. At 

 the base of the feet, where they are attached to the body of the 

 animal, there is a small papilla projecting at one corner, and 

 occurring in each foot.

Lepidonotus Lordi, Baird, Proc. Zool. Soc. April 1S63, 

 This species is about 3 inches in length, and rather more 

 than -^-rd of an inch in diameter at the broadest part of the body. 

 It tapers gradually from the head to tlie tail, which is only about 

 j^^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.. The head is broad and short; the eyes 

 are small, placed obliquely near to each other. The tentaculum 

 and antennae are very short, about equal in length, and white; 

 the bases of the antennae are produced from the anterior margin 

 of the head-lobe, and the tentaculum occupies a deep emargina- 

 tion on the front of the lobe. The palpi are stout, short, conical, 

 of a light colour, but close to the point ringed with black, the 

 point itself being quite white. They are a little longer than the 

 tentaculum and antennae. The feet are tolerably stout ; the two
