A single specimen of this species was obtained with thedredgo 

 off Broughton Islands near Port Stephens, at a depth of about 

 30 fathoms. 



Lepidonotus lissolepis, sp. n. (PI. YIIL, figs. 3 and 4.) 



The body consists of 25 setiferous segments with 12 pairs of 

 elytra. The mesial and lateral preestomial tentacles are subequal, 

 slender, tapering, smooth. The peristomial tentacles are nearly 

 equal in length, the inner much stouter than the outer ; the outer 

 together with the cirri are slightly swollen near the apex, which 

 is attenuated. The scales (which occur on the 1st, 2nd, 3rd, 5th 

 —21st segments) are smooth, rather delicate, not fringed, of a 

 dark slatey-brown colour, the pigment being arranged in minute 

 dense lobed corpuscles instead of separate granules. The para- 

 podia are not divided. The ventral set^, about 25 in number, 

 are constructed on a type similar to that exhibited by those of 

 Thormora argus, but have a small acute tooth near the apex. The 

 dorsal setse are slender with spinose transverse ridges assuming 

 the appearance of longitudinal lateral rows of teeth. The length 

 is 1th of an inch ; the breadth ^th of an inch. 

 Nelson's Bay, Port Stephens, 5 fath. 



This species seems to be aUied to L. striatus of Kinberg, but 

 evidently differs from it in the minute structure of the scales, an 

 well as in the greater relative shortness of the inner peristomial 

 tentacles. 



Lepidonotus simplicipes, n. s, (PL IX., figs. 1 and 2.) 



The body is composed, like that of the preceding species, of 

 25 segments bearing 1 2 pairs of elytra. The praestomial tentacles 

 are subequal, of a shape similar to those of the preceding species 

 and banded, as well as the other tentacle and cirri, with dark 

 brown. The inner peristomial tentacles are very thick, not 

 subulate, brown. The outer peristomial tentacles are equal in 

 length to the prsestomials and of similar shape. The anal cirri
