Anglo-Norman Islands. 239 



seaweeds. I maj cite, further, two species which appear to me 

 to be much m.oxQX2iXQ,x\Q.M\Q\j OUgocladus sanguinolentusyljang., 

 remarkable for the vivid coloration of the digestive tube, which 

 is strongly coloured red ; this I have met with only once at the 

 Gr^ve d'Azette (at the Pic-Triple rock) ; and Stylochoplayia 

 maculata, Stimps., of which I have found several specimens 

 behind La Motlie. 



Among the Nemertcans I shall mention, first of all. Linens 

 longissimus, Sim., which appears to be very common through- 

 out the south-eastern region of the island, and Lineus gesse- 

 rensis, Johnst., a small species of a dark green or nearly 

 black colour. Valencia s2)lendida, V. lo7igij'ostris, and V. or- 

 nata, discovered by Quatrefages at Breliat and at Chausey, 

 are abundant at La Eocque in muddy sand covered with 

 Zosterce, where they live with Marphysw^ ClijmenWj and 

 fossorial crustaceans. 



Of the other species which I have met with at Jersey, and 

 which I have been able to determine with certainty, 1 may 

 mention: — Tetrastemma ca/if/t Jmw, MiilL, a very abundant 

 species ; Ampjliiporus lactifloreus, M'Int., common under 

 stones among seaweeds ; and Polia Jilum^ Quatref., which no 

 doubt does not differ from Polia sanguiruha^ Quatref., for I 

 have observed passage-types between these two forms, which, 

 moreover, come very near to each other. 



From the Gr^ve d'Azette I have also obtained several 

 examples of Nemertes gracilis^ Johnst., and lastly some spe- 

 cimens of a bright rose-coloured Nemertes^ 4 or 5 centim. in 

 length, Avhich I refer, with some doubt, to Cerehratulus biline- 

 atuSj lien. 



I should also have to record a great number of Rhabdo- 

 coelans which live among the seaweeds, associated with 

 Nematodes and small Polychaita ; but I have neither the 

 time nor the books necessary for the study of these interesting 

 types, which I am unwillingly compelled to pass over. 



Polychoeta. 



Of the Aphroditina I shall first cite Aj^hrodite hystrix^ 

 Aud. & Edw., of which I have dredged several specimens in 

 St. Aubin's Bay. Mr. Sinel showed me some fine specimens 

 of A. aculeata, Linn., which he found in the same locality • 

 but for my own part I never met with that species. As to 

 the genus Polynoe, it is represented by P. cirrata^ Miill., a 

 very common species, and by P. squamata, Linn., and Lagisca 

 propinqua^ Malmgr., which are less frequent. To the same 

 family belongs Sthenelais Edwardsii, Quatref. 



To the Euniceans belong : Eunice Uarassii and E. Belliij
