Two specimens are from the Bay of Shoals, on the north- 

 -east coast of Kangaroo Island, and two are from Kingston, 

 Xacepede Bay (long. 139 c 80' E., lat. 36° 80' S.-). Their 

 ■dimensions are : — 



c(l) Total length 320 mm., the tail being 110 mm.

They are stout worms, the maximum girth of the largest 

 specimen being 56 mm. Their colour is brown (in alcohol), 

 the tail being paler than the rest of the worm, and in two 

 cases almost greyish in tone. 



In each worm the first gill is borne on the seventh seg- 

 ment, and the gills are pinnate. The third gill of specimen 

 \3) has seventeen main axes, each of which bears, right and 

 left, branches terminating in gill-filaments. 



The outlines of the prostomium are imperfectly preserved 

 in all the specimens. 



The neuropodia are of the usual elongate type, and their 

 chaetae (crotchets) are similar in general form to those of 

 South African examples, but have a sharper rostrum and dis- 

 tinct postrostral teeth are present. 



The notopodial chaetae differ from those of South Afri- 

 can specimens, as they do not present the well-marked 

 transverse »striation so characteristic of the latter. They are 

 provided with numerous pointed processes, (2> less regularly 

 arranged than in the South African examples, and almost 

 like those of A. cristata (compare fig. 12, p. 45, in Cat. Chaet. , 

 Brit. Mus.). Specimens of A. loveni from different localities 

 evidently exhibit some variation in regard to the processes 

 ■of their notopodial chaetae. The transverse striatum of these 

 chaetae, given in my previous accounts of A. loveni as a 

 specific character, proves to be a variable feature, and has 

 therefore been omitted from the statement of the diagnostic 

 characters of the species given above. 



Two of the specimens, one from each locality, have been 

 dissected. Both possess five pairs of nephridia and a single 

 pair of conical oesophageal glands. 



The septal pouches, the most striking internal feature 

 of this species, are of the usual large size, and extend back- 

 wrards, through apertures in the second septum, until they 

 almost reach the third septum. In the largest specimen (1) 

 the longer of the two septal pouches attains a length of 

 "23 mm.
