Anglo-Norman Islands. 241 



mention Aremcola piscatorum, Cuv., which abounds in the 

 sands of the shores, often accompanied hjA.ecaudata, Jolinst. ; 

 Clymene lumhricoides^ Edw., is frequent in the mud of La 

 Kocque, where Fetaloproctus tevricola^ Quatref., also lives. 



Cha^topterus Quatrefagesii, Jourd., is sometimes found under 

 stones ; its tube is attached to the under surface of pebbles, 

 and is not bent into a U. 



The Terebelloi are represented by Terehella nehidosa, Mont., 

 which is met with under stones, especially in places where 

 the water runs a little, and by T. conchilega, Pall., and 

 T. prudens, Cuv. ; these last two species, which live in tubes 

 constructed of sand and shell-fragments, are everywhere 

 abundantly distributed. 



Among the Sabellians I will cite Sahella pavonina^ Sav., 

 common in the meadows oiZostera-^ S. verticillata, Quatref., 

 which is pretty frequently met with in the midst of tufts of 

 Cynthia ; and, finally, S. arenilega^ Quatref. Protula pro- 

 tensa^ Grube, is found occasionally in the anfractuosities of 

 rocks. 



I will also mention Vermilia conigera and V. tricuspisj 

 Quatref., Serpula fascicularis, Lam., Spirorlns communis^ 

 Flem., generally-distributed species, and, lastly, Salmacina 

 Dysteri, Quatref. ; in this last species, as is well known, the 

 tubes which protect the individuals become united into volu- 

 minous ramified masses, thus forming a sort of polypary, as 

 is also the case in an allied Mediterranean species, S. wdifi- 

 catrix. The specimen of Salmacina that I possess was given 

 to me by a fisherman, and came from the open sea. 



Among the other groups of Vermes I must cite two Gephy- 

 rians {Phascolosoma margaritaceum^ Sars, and P. elongatam, 

 Kef.) as pretty common in muddy places. 



A few words ought, perhaps, to be said of the Bryozoa • 

 but as I have few remarks to make as to the habitat and 

 stations of the difierent species, I shall content myself with 

 giving hereafter the list of the species that I have met witli. 



As regards the Brachiopoda, I will only remark that 

 M. Duprey found on the coast a small species of Argioj^e {A. 

 capsida, JefFr.), under pebbles buried in the beach to a depth 

 of 8 or 10 inches, associated with Chiton scabriculus, Ade- 

 orhis subcarinatus, &c.
