Strandes, p. 177. 1903. A. assimilis, var. affinis, Ashworth. Quart. Journ. 

 Micros. Sci., xlvi, p. 737, pis. xxxvi, xxxvii. 1907. A. claparedi, Ehlers, 

 Neuseel. Annel., ii, p. 21. 



This variety, whose anatomy is fully described by Ashworth, differs but slightly 

 from Ehlers' species, and it appears that both the species and its variety overlap 

 in their distribution. 



In his memoir on New Zealand Annelids, above quoted, Ehlers identifies the 

 New Zealand species, although with some hesitation, as A. claparedi ; but in a letter 

 to me, after he had examined a well-preserved specimen which I forwarded to him, 

 he writes, " The animal possesses otocrypts with foreign bodies," and acknowledges 

 the correctness of Ashworth's conclusions. 



The possible identity with some of the species described by Grube and by 

 Schmarda is dealt with by Ehlers and by Ashworth. 



Locality. — Campbell Island; (G. R. Marriner, 1907). Macquarie Island; 

 (A. Hamilton, 1894). 



Distribution. — The variety occiirs on the coast of New Zealand and Falkland 

 Islands, and its post-larval stages have been detected off Tierra del Fuego.

This common cirratulid, which is fully described by Ehlers, lives in mud at and 

 below low water. The body is orange or brown in colour, and measures about 

 75 mm. in length. 



Locality. — Auckland Island : Carnley Harbour ; (W. B. B.). 



Distribution. — Commonest cirratulid on the shores of New Zealand ; it also 

 occurs at Chatham Island, and is said to occur in Port Jackson, Australia 

 (Kinberg).

 Although Ehlers in his last memoir points out that Schmarda' s two species above 

 included in the synonymy are identical with one another, and are synonymous with
