186 Mr. E. Duprey on Jersey Littoral Shells. 



soil, thus supplying the wants of the little inhabitants, who, 

 if deprived of light, live concealed, and thus protected, from 

 many of their enemies. 1 may add that the shells of the 

 Rissoas and Chitons are not worn, as must be the case if they 

 were habitually rubbed against and forced through sand. 



Beyond low-water mark, secure in this " buried habitat," 

 these and other perhaps unknown species may long defy the 

 efforts of the dredger. 



Most of the species have been found alive ; when otherwise, 

 mention is made that dead shells only have been met with. 



The nomenclature is that of Dr. Jeffreys's l British Con- 

 chology ; * and in this, as well as in my first list of Jersey 

 shells, the more rare or doubtful species have been submitted 

 to the kind inspection of Dr. Jeffreys. 



Brachiopoda. 



Argiope capsula, Jeffr. This minute shell, hitherto obtained only 

 with the dredge, is also an inhabitant of the littoral zone on 

 several parts of the coast of Jersey, where it is found in the 

 " buried habitat " previously described ; often in company with 

 Chiton scabridus* Adeorbis subcarinatus. and other sneciea-

be seen attached to the same stone. I have even met with it 

 under some which were completely hidden from view beneath the 

 soil. But the advancing tide will seldom permit one to pick them 

 all from the rough surface, as this must be done one by one, for 

 they are easily crushed. A brush does not answer. Full-grown 

 shells are about 0*04 inch in length. The colour is white ; but 

 very often they have a rusty appearance, from being attached to 

 a piece of ferruginous hornblendic rock. 



CONCHIFERA. 



Lima subauriculata, Mont. Yalves only ; they are not uncommon 



in shelly gravel, 

 Mytilus modiolus, L. Valves only. 

 Modiolaria marmorata, Forbes. As usual, in the skin or tegument 



of an ascidian affixed to the M roots " of a Laminaria. Also 



amongst seaweeds (young specimens). 

 Crenella rhombea, Berkeley. A few valves in shelly gravel in Pon- 



tac and Samares Bays. 

 Lepton nitidum, Turt. Valves only. 



Jeffr. In sittings ; rare. 



ChirJcice, Clark. Found living in St. Aubin's and Samares 



Bays. The young shells are transparent and glossy ; the adults 

 generally have a rusty appearance. Odd valves are not un- 

 common. 



MontactUa bideniata, Mont. Dead shells in St. Aubins Bay.
