188 Mr. E. Duprcy on Jersey Littoral Shells. 



of British mollusks is not uncommon in the " buried habitat * 

 before mentioned ; as many as half a dozen occur sometimes under 

 one stone, C. cancellatus is occasionally found with it. Adult 

 specimens are $ inch long. For description of animal and shell 

 see the * Annals & Magazine of Natural History ' for July 1880. 



Cyclostrema nitens, Phil, Not full-grown ; in sittings from Sa- 

 mares Bay. 



Trochus tumidiis, Mont. Dead shells are not uncommon in shelly 

 gravel from about low-water mark in the same locality. 



cinerarius, L., var. paUescens. Without coloured markings ; 



corresponding with the variety paUescens of T. umbilicatus. 

 JRissoa cancellata, Da Costa. Found dead with Trochus tumulus. 

 Although a common Herm shell, I have not found it alive in 

 Jersey, where in its place R. lactea is rather common. Of this 

 last I have several times found more than a dozen, and once forty- 

 three alive, under one stone. 



calathus, F. & H. With R. cancellata, but more rare ; dead 

 shells only* 



inconspicua, Alder, var. variegata. 



fulgida, Adams. Abundant. 



, var. pallida. 



semistriata, Mont., var. pura. 



Hydrobia ulvce, Penn. Rather small. 



Jeffreysia diaphana^ Alder. Obtained by sifting small seaweeds. 



My largest are hardly 0-06 inch long. 

 opalina, Jeffr. With the preceding ; my largest are only 0*06 



inch in length. 



SJcenea planorbis, Fabr., var. maculata. 



, var. hyalraa. 



These two varieties live amongst small seaweeds, whereas I 

 find the reddish-brown or typical form in fine gravel. 

 Homalogyra atomus, Phil., var. vitrea. 



Another variety has on the last whorl three reddish-brown 



bands on a light-coloured ground. 



rota, F. & H. In sittings from St. Aubin's and Samares Bays 

 and from Pointe des Pas. Occurs sparingly, and is difficult to 

 find, on account of its extremely small size. 

 Truncatella truncatula, Drap. Dead shells. 

 Aclis uniea, Mont. In sittings from Pointe des Pas. Bare. 



supranitida, S. Wood. A dead specimen in fine shelly gravel. 



Odostomia nivosa, Mont. In rock-pools. 



Lxikisi, Jeffr. Dead specimens. 

 albella, Loven. Not uncommon in rock-pools.
