Depth. Littoral, and down to 88 meters. 



Notes. The specimen has thirty-eight arms about 110 mm long; all 

 the II Br series are 4 (3 + 4); eleven of the IIIBr series are 2 and seven 

 are 4 (3 + 4); the cirri are XXX, 4244, about 30 mm long; they are 

 typically large and stout; the spines commence on the thirteenth or four- 

 teenth segments; the proximal pinnules are considerably larger on the outer 

 arms than on the inner; PD is 15 mm to 17 mm long with from twenty- 

 eight to thirty segments, and is moderately stout. The colour is purplish 

 white, becoming deep purple on the arms ; the proximal part of each seg- 

 ment is crossed by a deep purple band ; the cirri are purple, becoming 

 darker in the distal half.

Depth. Littoral, and down to 36 meters. 



Notes. In this specimen the cirri are stouter than usual, approaching 

 the condition found in A. Milberti, though the individual should undoubtedly 

 be referred to A. discoidea ; there are from 42 to 47 cirrus segments, of 

 which the twentieth or twenty-first and following bear dorsal spines; the 

 longest cirrus segments are slightly less than twice as broad as long; the 

 cirri reach a length of 40 mm ; the synarthrial tubercles between the elements 

 of the I Br series and between the first two brachials are prominent and 

 conical with the apex sharp, though not especially produced. This example 

 agrees well with a specimen from Port Molle in the collection of the 

 Australian Museum at Sydney, though the cirri are a trifle less tapering 

 distally and the dorsal spines on the cirri are a trifle shorter.
