Reeve's figure of the species*^' is of his A. pileolum. 



£^iA 



A. Jimhriatum. 

 Fig. 1. — Neanic stage and opercukim thereof, and adult opercukim. 



Tiyon regards A. squamiferum as a variety of A. Jimhriatum, 

 whilst Fischer {loc. cit.) and Tate and Mayf consider the name 

 an absolute synonym, a decision which is doubtless correct. 



Other varieties, according to Tryon, are A. pileolum, Reeve 

 (1842), and A. cucullatum, Kiener | The former is decidedly a 

 distinct species: the latter will most likely be found to be distinct 

 also, unless perhaps it is a variety of A . teutoriforme. 



This species is not so common in Port Jackson as the succeeding.
