Anglo-Normaii Islands. 235 



there are muddy sands in which live numerous Annelides, 

 common enough elsewhere: — Cirratidiis LamarcJdi., Terebella 

 conchilega, Nephthys Homhergii^ Arenicola inscatorum and A. 

 ecaudata. Synaptce are very frequent there. At this station 

 I have also collected numerous examples of Corystes cassive- 

 launus. The fishermen come to this locality to collect Solens, 

 which are very abundant there. 



To the west of the castle there are meadows of Zostera^ 

 abounding in species of Mysis associated with Themisto 

 brevispinosus, Oastrosaccus sanctics, and other Cumacea3, Idofea 

 linearis and acuminata^ Eolis Cumeri^ Doris Johnstonii^ D. 

 tuhercuJata and D.jlammida^ Triopa claviger, &c. The Aplysice 

 are very abundant here in certain years. Towards tlie south 

 the sands become less muddy, and are replaced by gravels 

 rich in fragments of shells, and in which Molgulai {Anu- 

 rella roscovita) abound. There we also find Pirimela denti- 

 cuJata. 



Tlie rocks, especially at the Hermitage, are covered with 

 tufts of CyntJiia rustica, under which live numerous species of 

 crustaceans and worms ; we also find here Ascidia producta^ 

 Ascidiella scabra, Cynthia granulata, and several species of 

 Sponges [Leuconia nivea, Dictyocylindrus ramosus, Hali- 

 chondria 'incrusta7is, Isodictya cinerea^ &c.). 



As to the rest of St. Aubin's Bay, the sea there, in retiring, 

 lays bare an immense uniform sandy beach, possessing no 

 interest for the zoologist, who will only find in it some very 

 common Annelides and Synapitoi. 



At the other extremity of the bay, opposite the little town 

 of St. Aubin, some rocks appear, one of which bears an old 

 castle. The Alga? which cover the stones contain some interest- 

 ing Crustacea : — Idotea linearis^ I. acuminata, and /. tricuspi- 

 data, Atylus Swammerdamii, Podocerus falcatus, and Anonyx 

 Edtvardsii. I have also met with a Doris Johnstonii, and 

 some Tunicata [Ascidia mentula and A. producta, Ciona intes^ 

 tinalis, Aynaroucium Nordmanni and A. albicans, Didemnum 

 sargassicola, &c.). 



Quitting St. Aubin the coast rises and the rocks become 

 rather scarped as far as the Corbi^res, except in the Bay of 

 St. Brclade. The bottom of this bay slopes very little, but it 

 possesses no interest for the zoologist, as tlie fauna is null. 



The western coast of the island from the Corbi^res to Cape 

 Gros-Nez is occupied by a long, uniform, sandy beach — the 

 Bay of St. Ouen. All the bottom of this bay is arid and dry, 

 and the collections which I have made there are insignificant. 



As to the north coast of Jersey it presents almost through- 

 out its whole length a series of escarpments, and is bounded
