Sectio I].—Testa inflata, levis, spiraliter striata. Canalis effusus, plus 
minusve elongatus. Apertura ovalis. Columella mutica, rarius subaspera, 
aut fastigiata. Operculum corneum. 
Fusus, Lamarck et Auctorum. 
The Murices of this section are the Fusi of authors, most 
of which are deep-sea species, as the M. antiguus, M. Turtoni, 
M. Norvegicus, M. Berniciensis, M. Islandicus, &c., and the 
M. borealis. None of these, except the M. Islandicus, occur 
on the southern coasts, and that we have had no opportunity 
of examining for several years ; but for the type of the animal 
of the enumerated species, we refer with perfect confidence to 
either of our descriptions of the M. erinaceus, M. lapillus, 
M. undatus, or any other in our list, which will furnish every 
essential generic character; and I fully expect to have it in 
my power, by the examination of live specimens of M. Islan- 
dicus, to show the correctness of their assigned position as 
members of the genus Murex. I can say nothing of the 
animal of M. borealis, which is admitted here as probably 
belonging to this section.
