of numerous pustules over the surface, but the tips are smooth (pi. 26, 

 fig. 320). 



The neuropodial setae project from the neuropodium in three series 

 (pi. 1, fig. 11). There are 2 heavier, longer superior setae, 2 or 3 

 slenderer median setae of about the same color, and 3 or 2 still finer, 

 somewhat paler inferior setae. All are falcate distally, with a minute 

 spur near the point where the seta curves (pi. 1, figs. 12 to 14). This 

 condition contrasts with that in A. armifera where only the inferior- 

 most setae have a lateral projection, also in the latter the spur is paired 

 (pi. 1, fig. 6). The elytra are pale or white, smooth save for a few 

 scattered prickles. 



Fauvel (1917, p. 167) reported and described a single specimen from 

 southern Australia, which he referred to A. talpa Quatrefages. The 

 same specimen he later (1925, p. 144) referred to A. ar?ntfera Moore. 

 The dorsal setae were described as follows: "Bronzees ou dorees, plutot 

 courtes, droites ou legerement incurvees et depassent peu I'epais et 

 grossier feutrage dorsal." In the specimen at hand, these setae are yel- 

 low, only the neuropodial setae are bronze. In other respects the speci- 

 men from Carros Island agrees with the description given for the indi- 

 vidual from southern Australia. In my opinion this is different from A. 

 armifera Moore.

Length to 20 mm, width to 7 mm. Number of setigerous segments 

 32. Dorsum pale, the elytra imbricated and not concealed by felt, but 

 laterally somewhat covered by foreign matter that is enmeshed in the 

 strong dorsal spines. Notopodial setae pale amber, neuropodial setae 

 somewhat darker. Ventrum pale save for dark spots that form a pat- 

 tern, consisting of a pair along the mid-ventral line, and one or two 

 irregular pairs along the sides, median to the parapodia. The dark spots
