194 " ENDEAVOUR " SCIENTIFIC RESULTS. 



As in other species, the ground colour of the elytron is 

 white, and the surface covered with variously coloured 

 stellate tubercles of a regular form, some of which may con- 

 tain black pigment ; these stars may be carried by short 

 cylindrical bases. Near the external, anterior margin are a 

 few soft, uncoloured, simple conical papillae (PI. xxxix., 

 fig. 30). 



Tn the larger individual the elytra are a good deal paler 

 than in the shorter one, owing, of course, to the less amount of 

 the black pigment in the tubercles, or rather to the fewer 

 black stars. 



The gills. — On the anterior face of the parapodia, there is 

 a row of 3 or 4 papulae in a line, starting from one at the 

 outward corner of the cushion, the distal one of the row being 

 near the notopod. There may also be, on the cirriferous 

 segments, an additional papula at a lower level on the face 

 of the foot about half way along. On the posterior face 

 there is a large papula close to the cushion, larger than any 

 of the others, which in cirriferous segments is clavate rather 

 than finger-shaped (PI. xxxix., fig. 32). 



At a lower level is a row of smaller papuhie, commencing 

 at the axilla, and inclined downwards ; in the cirriferous 

 there are two, and the elytriferous three, in this row. 



The prostomium is as broad as its length, broadest almost 

 at its hinder border. The two pairs of eyes are even further 

 back than in P. rugosus, very close together, the ant-erior at 

 rather a higher level than the posterior ; they are oval in 

 outline, with the longer axis vertical, and is best seen in 

 side view (PI. xxxix., figs. 26, 27). 



The tentacles are broken off in the larger specimen (the 

 type), and in the smaller only one lateral tentacle remains. 

 This is reddish browii right up to the swelling, which is white ; 

 the tentaculophore is vandyke-brown. 



The tentacle is proportionateh^ as long as that of P. 

 rugosus. 



As in other species, the hinder margin of the prostomium 

 is overlapped by the first " pad " for the elytra. 



The double " pads " occur on segments 2-13 inclusive. 



Locs. — Twenty-five miles south-west of Cape Everard, 

 Victoria. This specimen has been selected as the type. 



Off Gabo Island, Victoria, 200 fathoms, with P. pauci- 

 branchiatus.
