-_—— 
It will be noticed, that of the foregoing list, there are only Trochus umbi- 
licatus and crassus (doubtful), and perhaps Chiton marginatus (a doubtful 
determination), British species not found in the Mediterranean. 
Dredged at San Lucar de Barameda (mouth of the Guadalquivir), 12th, 
21st, and 22nd of April, locality not favourable for dredging ; bad enough for 
anchorage on account of the strong tide and freshwater coming down after 
the heavy rains—sandy shore. The most abundant species were Mactra 
stultorum, ordinary variety, and one pure white in about equal plenty; 7 ἴ- 
fina coste not uncommon ; valves of Lutraria rugosa small. Numerous com- 
mon South European species. 
Between the bar of San Lucar and Cadiz I made use of the dredge at 
Various points, in 8 to above 20 fathoms, and found the bottom to be black 
€pidermis furnished with minute tufts of hair arranged in rows, diverging from the limbs, 
Giving it the appearance of being striated. 
N.B. I have formerly found dead and worn specimens on the shore of Asturias, when I 
Supposed it to be Bornia complanata. 1 procured the same, or an allied species, smaller, 
_ dead, from mud in Vigo. 
T Possibly a variety of T. articulatus, or intermediate between the two species.
