 cular and somewhat flattened papillae on each side. 



Of the forms new to Britain are : — Harmothoe longisetis^ 

 Grube^ which, however, I think, is H. Malmgrenij Lankester^, 

 and thus has been previously got in this country. Sigalion 

 limicolaj Ehlers^. Nephthys ciliata^ Miill.* Genetyllis lutea^ 

 Mgrn.^ Anaitis hosteriensis (?), Mgrn.* Lumhrinereis fra- 

 giliSj Mull.', a species which probably includes L. tricolor 

 and some others, and therefore has been found previously on 

 British shores. Onuphis sicula^ Quatref.^, a curious species 

 (inhabiting a tube composed of shell-fragments, stones, and 

 sand), allied to 0, tubicola^ but differing entirely in the struc- 

 ture of certain of its bristles. Eone Nordmannij Mrgn.* 

 Scoloplos armtger, Miill.^^ Naidonereis quadricusjpidata

 partly from their fragmentary state, has not been completed,
