of each is pigmentless and transparent, the pigment is rather 

 darker round the areola especially in the posterior region. 

 The pigment occurs as minute black granules in certain 

 round cells rather widely scattered amongst clear empty 

 cells (PL xxxviii., fig. 2). There is no fringe. 



The notopodium (PL xxxviii., fig. 4) is small, and contains 

 about 12 pale almost colourless chsetaj, all alike, with 

 incomplete spiral frills : for in some aspects the serrulations 

 appear to be limited to one side. 



The neuropodium is bluntly pointed, with yellow-golden 

 chsetse, thicker than the notopodials, about 24 or 25 in 

 number ; these have a subapical tooth, and from 1) to 15 

 pectinated frills, according to their position in the bundle ; 

 the most distal frill having large teeth (PL xxxviii., figs. G, 7). 



The dorsal cirrus is pale brown for about half way along 

 its length, then white, with a dark band a little below the 

 tip, giving the appearance of a subterminal swelling. 



The prostomium is typically lepidonotan ; it is as long 

 as its breadth. The anterior eyes are at its widest point ; 

 the posterior pair are far back, close to the nuchal fold. 



The tentacles are smooth ; the median is lacking. The 

 laterals are long slender, and colourless, except for a pale . 

 grey ring below the subterminal swelling. 



Remarks. In L. lissohpis, Haswell, from Port Stephens, 

 the elytra are described as '" smooth, rather delicate, dark 

 slatey-brown. the pigment being arranged in minute dense 

 lobed corpuscles instead of in separate granules." This 

 appears to be quite different from the arrangement above 

 described, and his figure of the chaetae is too poor to be sure 

 that it agrees, except in a rough way, with those of the 

 present species. 



L. purpureus, Potts, 1 is also only briefly described. Its 

 colour, however, is said to be " purple brown," and the pig- 

 ment is " concentrated in little masses " between clear cells, 

 giving a honeycomb appearance. 



The surface of the elytron is " strewn with little chitinous 

 tubercles showing a slight median depression." 



His figure is not very clear, though if the dark circular 

 things are meant for the tubercles they do not agree with 

 those before me. 



But both these seem from other features to be nearly 

 allied to one another and to the present.
