PoLYCiRRUS CALiENDRUM Claparede : de St. Joseph, Ann. Sci. Nat. Zool. 

 XVII. 1894, p. 237. 



Plymouth. Common in dredgings from all parts of the Sound, 

 especially in Millbay Channel. Dredged also in Yealm River. Occa- 

 sional specimens amongst weeds and Laminaria roots from the shore. 



In the former list two species P. aurantiacus Grube and P. calien- 

 drum Claparede were recorded. The specimens included under 

 the former name were those which are generally of large size and of 

 a bright scarlet red colour. They have, however, three large pairs 

 of nephridia and three small pairs as in P. caliendrum. The typical 

 specimens of P. caliendrum, which were referred to in the former 

 list, are of various shades of yellow, some being quite pale. They 

 have six pairs of nephridia arranged as in the bright red form. I am 

 inclined to agree with Southern's suggestion (Proceed. R. Irish Acad. 

 XXXI. 47, 1914, p. 127) that P. aurantiacus and P. caliendrum may be 

 identical, in which case the name P. aurantiacus Grube should 

 have precedence. McIntosNs recent description of P. aurantiacus 

 Grube (Ann. Mag. Nat. Hist. XV. 1915, p. 33) would appear to apply to 

 the species now under discussion, and he speaks of a red variety. 



Salcombe. Both varieties dredged between Salstone and Snape's 

 Point (Journ. M.B.A., vol. 6, 1900, p. 197).

 Zool. XVII. 1894, p. 241. 



Plymouth. Not uncommon in dredgings from the Sound, 

 especially from Millbay Channel and Asia Shoal. It is much less 

 numerous than P. caliendrum.

 Rame Head. 



AMPHARETIDJE. 



Melinna adriatica Marenzeller : Adriatische Anneliden. Sitzb. Akad. 

 Wien, Bd. 69, 1874, p. 472. 



Plymouth. Very common in soft mud in Plymouth Sound. 

 Found both on the shore at low water and also by dredging. 



Salcombe. In fine mud in the upper parts of Salcombe and 

 Kingsbridge Estuary in very great abundance. Probably the 

 Sabella curta of Montagu (Joum. M.B.A., vol. 6, 1900, p. 197).
