Mr. E. Duprey on Jersey Littoral Shells. 187 



Ktllia suborbicularis, Mont. This is a newly recognized inhabitant 

 of the middle portion of the littoral zone, where it was first found 

 by the Rev. F. Lallour in shallow rock-pools, nestling in the nooks 

 and crevices in the thick calcareous crusts of Melobesia polymor- 

 ph*- . I hare met with it on several parte of the coast in this 

 habitat. This is perhaps a littoral variety ; the incurrent tube 

 of the animal is fully as long as the shell is wide, whilst the ex- . 

 current tube is sessile. My largest specimen is | of an inch in 

 breadth. 



Axinus flexuosus, Mont. Found living in sand amongst Zostera 



with Loripes lacteus and Lucina boreah's (a small var.). Odd 



valves are very common in St. Aubin's Bay. 

 Cyamium minutum, Fabr. In rock-pools amongst small seaweeds ; 



far from common and of a whitish colour. 

 Cardium tuberculatum, L. Living, in St. Aubin's Bay. 



fasciatum, Mont. A valve only. 

 Circe minima, Mont. Living at low water in coarse gravel at La 



Rocque and in Samares Bay. 

 Venus gallina, L. In St. Aubin's Bay. 

 Lucinopsis undata , Penn. In gravelly sand at La Rocque. 

 Tellina pusilla, Phil. Dead but fresh-looking shells. 



Psammobia tellinella, Lam. Besides the ordinary or coloured 



form 



occurs 



Ferroen&is, Chemn. Living in St. Aubin's Bay. 



Donax politics, Poll. Sometimes of a uniform very light colour 

 (one only). 



Scrobicularia prismatica, Mont. Dead shells. 



— alba, W. "Wood. Living in sand. 

 Ceratisolen legumen, L. Dead shells only. 

 Solen pellucidiis, Penn. A few specimens with S. ensis in St. 



Aubin's Bay. Both species emerge quite out of the sand as the 



tide begins to rise. 



Thracia papyracea, Poli. This and the next species have been 

 found alive at La Rocque (Rev. F. Menard). 



CorbuU gibba, Olivi. 



Saxicava rugosa, L. In default of limestone this boring shell avails 

 itself of the thick calcareous crusts of Melobesia, where it is occa- 

 sionally found in rock-pools not much below half-tide. Young 

 and very small specimens are also found nestling in the crevices 

 of pieces of cork (net-floats). 



Teredo naval is, L. In timber from the lower portions of the old 

 landing-stage in Yictoria Harbour. 



megotara, Hanley, var. mionota. In floating timber, ca9t 

 ashore. 



, var. suhericola. This minute form is occasionally found 



alive or quite fresh in bottle-corks and net-floats left on the shore 

 by the tide. 



Gastropoda.
