eS THE DEPTHS OF THE SEA. [ CHAP. Iv. 
MatMGREN, both of them Arctic species. ‘The LOth 
was Sunday, and the vessel lay-to, and on the 11th 
they dredged, still on the slope of the channel plateau, 
with nearly the same result as before, the fauna 
maintaining the same character. 
Mr. Gwyn Jeffreys was now anxious to get a haul 
or two in the very deep water off the mouth of the 
Bay of Biscay, which we had explored successfully 
in 1869. ‘They therefore steamed southwards, going 
a considerable distance without dredging, as they 
were afraid of coming in contact with the cable 
between Brest and North America. When they got 
to their ground unfortunately bad weather set in, 
and they were obliged to make for Vigo. On Thurs- 
day, July 14th, they passed Cape Finisterre, and 
dredged in 81 fathoms about 9 miles from the 
Spanish coast. Along with a number of familiar 
forms, some of them with a wide northern exten- 
sion, they here took on the tangles two specimens, 
one young and one apparently mature, both con- 
siderably injured, of the singular Echinidean already 
mentioned, Calveria fenestrata. This is evidently 
not a rare form, nor is it confined to very deep water ; 
it is rather remarkable that it should have escaped 
notice so long. On the 15th, they sounded in from 
100 to 200 fathoms, about 40 miles from Vigo, and 
on the 16th took one or two hauls in Vigo Bay at 
a depth of 20 fathoms. This locality had already 
been well-nigh exhausted by Mr. McAndrew in 1849, 
and only a few additions were made to his list. 
They left Vigo on the 18th. I quote from Mr. 
Gwyn Jeffreys :—
