them are marked with spots of dark blue, there are bands of a 

 similar colour on the cex^halic tentacles, and two dark blue spots 

 on the ventral surface of each segment. Length about f ths of 

 an inch ; breadth ^th. 



I found specimens of this species under stones between tide- 

 marks on Thursday Island. 



Lepidonotus torresiensis, sp. n. (PI. IX., fig. 6.) 



The body contains 25 segments bearing 12 pairs of scales, 

 which are imbricate and decussate. The mesial prrestomial 

 tentacle is about twice the length of the head, with a subapical 

 swelling and filiform extremity, as in most of the preceding 

 species ; the lateral praestomials are a little shorter than the 

 middle and of similar shape. The inner peristomials are rather 

 shorter than the outer in one specimen, a little longer in another, 

 thick at the base, acuminate at the apex. The outer peristomials 

 are as long as the proestomials and of similar shape. The scale- 

 tubercles arp» very prominent. The ventral setse are very similar 

 to those of L. simjolicipes ; the dorsal setoe are short with two 

 longitudinal rows of short spines. The scales are subreniform, 

 thickly, fringed ornamented on the upper surface with a few 

 conical and clavate processes. The colour is light grey, with a 

 darker spot at the point oi attachment of each scale. 



Dredged off Thursday Island in 3-5 fathoms. 



This species seems to resemble L. Bowerhankii'va. some respects, 

 but the presence of a tooth on the ventral setfe distinguishes it 

 from the latter. 



Lepidonotus dictyolepis, sp.n. (PI. IX., figs. 7 and 8.) 



There are 25 segments bearing setae and 12 pairs of elytra. 

 The prsestomial tentacles are nearly equal, inserted in a line, the 

 mesial rather longer, twice the length of the head, the basal half 

 rather stout, the distal half slender, rather clavate at the apex
