270 THE DEPTHS OF THE SEA. [cHap. VI. 
bergen expedition in the ‘Maclean nets,’ and in 
the same year O. Torell alludes to one of the crus- 
taceans from that depth being of a bright colour.t 
In 1846 Captain Spratt, R.N., dredged at a depth 
of 310 fathoms forty miles east of Malta a number 
of mollusea which have been subsequently examined 
by Mr. Gwyn Jeffreys and found to be identical 
with species dredged at considerable depths in the 
northern seas during the ‘Porcupine’ expedition. 
The list includes Leda pellucida, Puttipp1; Leda 
acuminata, JEFFREYS; Dentalium agile, SARS; JTela 
tenella, JEFFREYS; Hulima stenostoma, JEFFREYS; 
Trophon barvicensis, JOHNSTON; Pleurotoma cari- 
natum, Bivona; and Philine quadrata, 8. V. Woop. 
Captain Spratt observes that he ‘believed animal 
life to exist much lower, although the general 
character of the Algean is to lmit it to 300 
fathoms.” ’ 
In 1850 Michael Sars, in an account of a zoolo- 
gical excursion in Finland and Loffoten, expressed 
his conviction that there is a full development of 
animal life at considerable depths off the Norwegian 
coast. He enumerated nineteen species taken by 
himself at depths beyond 3800 fathoms, and pointed 
out that two of these were the largest species 
known of their respective genera.’
