1901. Pecten bifrons. Tate and May. P.L.S. N.S.W., 

 vol. xxvi., pt. 3, p. 440. 

 Hab. — San Remo, Western Port. Portland (Maplestone). 

 Obs. — This species shows considerable variation, and we think 

 it probable that a full series will necessitate the inclusion with it 

 of the foregoing species, P. undulatus, for both P. tasmanicus, 

 Adams and Angas, and P. mariae, T. Woods, show such inter- 

 mediate characters as to point strongly in this direction.
